The watch ships without a built in PDF viewer, so you need a small companion app to carry the file across. <a href=\"https:\/\/apps.apple.com\/app\/id6762510888\" target=\"_blank\" rel=\"noopener\">WristFile<\/a> handles that handoff and stores the document on the watch for offline reading.<\/p>\n\n<p class=\"wp-block-paragraph\">Apple designed watchOS around glances and quick actions, not long documents. That is why a raw PDF will not open on the watch by itself. A dedicated reader fills the gap by rendering each page for the small screen.<\/p>\n\n<p class=\"wp-block-paragraph\">The transfer runs over the same wireless link your watch already uses to sync apps. You pick a PDF on the iPhone, send it, and it lands in the watch app a few seconds later. After that, the file lives on the watch.<\/p>\n\n<p class=\"wp-block-paragraph\">I tested this with a two page parking permit before a trip. I sent it from the iPhone in the kitchen, then left the phone on the charger. The permit still opened on my wrist in the car. Offline access is the whole point.<\/p>\n\n<p class=\"wp-block-paragraph\">You can read more about the reading experience in our guide on <a href=\"https:\/\/pdfapplewatch.com\/blog\/how-to-view-pdf-apple-watch\/\">how to view a PDF on Apple Watch<\/a>. This article focuses on the transfer step, the part that trips up most new users.<\/p>\n\n<p class=\"wp-block-paragraph\">The takeaway is simple. Transfer is possible today on current Apple Watch models. You need one app on both devices and a single tap to send. Everything after that works without your iPhone in range.<\/p>\n\n<h2 id=\"what-you-need\" class=\"wp-block-heading\">What you need before you transfer a PDF<\/h2>\n\n<p class=\"wp-block-paragraph\">Before the first transfer, check three things: your watch model, your watchOS version, and the app on both devices. Most setup problems trace back to one of these.<\/p>\n\n<p class=\"wp-block-paragraph\">Apple Watch Series 6 and later handle document apps well. Older models run watchOS versions that lack the storage and rendering support modern readers expect. If you own a Series 4 or 5, transfers may work, but performance drops on large files.<\/p>\n\n<p class=\"wp-block-paragraph\">Your watchOS version matters more than the model. WristFile targets watchOS 10 and newer. You can confirm your version in the Watch app on iPhone, under General, then About. Apple lists the current feature set on its <a href=\"https:\/\/developer.apple.com\/watchos\/\" target=\"_blank\" rel=\"noopener\">watchOS developer page<\/a>.<\/p>\n\n<p class=\"wp-block-paragraph\">The companion app must be installed on both the iPhone and the watch. When you download WristFile from the App Store, the watch app usually installs on its own. If it does not appear, open the Watch app, scroll to the app list, and toggle it on.<\/p>\n\n<p class=\"wp-block-paragraph\">Storage is the last check. PDFs are light, but image heavy files add up. A typical text PDF uses under one megabyte. A scanned, photo rich document can use ten times that. Apple explains how watch storage is managed in its <a href=\"https:\/\/support.apple.com\" target=\"_blank\" rel=\"noopener\">support documentation<\/a>.<\/p>\n\n<p class=\"wp-block-paragraph\">Here is a quick readiness table before you send your first file.<\/p>\n\n<figure class=\"wp-block-table\"><div class=\"table-wrap\" style=\"overflow-x:auto;-webkit-overflow-scrolling:touch\"><style>.wp-block-table table{border-collapse:collapse;width:100%;min-width:520px}.wp-block-table th,.wp-block-table td{border:1px solid #e3e1de;padding:10px 14px;text-align:left;vertical-align:top}.wp-block-table thead th{background:#FDEDEC;color:#15161A;font-weight:700}<\/style><table><thead><tr><th>Requirement<\/th><th>Minimum<\/th><th>Recommended<\/th><\/tr><\/thead><tbody><tr><td>Apple Watch model<\/td><td>Series 6<\/td><td>Series 9, 10, or Ultra<\/td><\/tr><tr><td>watchOS version<\/td><td>watchOS 10<\/td><td>watchOS 26<\/td><\/tr><tr><td>iPhone<\/td><td>iOS 17<\/td><td>iOS 18 or later<\/td><\/tr><tr><td>Free watch storage<\/td><td>50 MB<\/td><td>200 MB or more<\/td><\/tr><\/tbody><\/table><\/div><\/figure>\n\n<p class=\"wp-block-paragraph\">Run through this list once. After that, every future transfer takes seconds.<\/p>\n\n<h2 id=\"how-to-transfer-steps\" class=\"wp-block-heading\">How to transfer a PDF with WristFile, step by step<\/h2>\n\n<p class=\"wp-block-paragraph\">The transfer is a five step flow inside one app. Each step happens on the iPhone, and the watch receives the file automatically.<\/p>\n\n<ol class=\"wp-block-list\"><li>Open WristFile on your iPhone and tap the import button.<\/li><li>Choose your PDF from Files, Mail, iCloud Drive, or another app share sheet.<\/li><li>Confirm the file name and preview the first page.<\/li><li>Tap Send to Watch to start the transfer.<\/li><li>Wait for the progress ring to finish, then check your wrist.<\/li><\/ol>\n\n<p class=\"wp-block-paragraph\">The first transfer of a session can take longer while the devices wake their connection. Later files move faster because the link is already active. A two page PDF usually lands in under ten seconds.<\/p>\n\n<p class=\"wp-block-paragraph\">You can queue several files at once. Select multiple PDFs in the import screen, then send them in a batch. The watch app shows each one in a list, sorted by the time it arrived.<\/p>\n\n<p class=\"wp-block-paragraph\">The send works over Bluetooth when the devices are close, and over wifi when they share a network. You do not pick the method. The system chooses the fastest available path on its own.<\/p>\n\n<p class=\"wp-block-paragraph\">Here is what each step looks like in practice, with the action and the result side by side.<\/p>\n\n<figure class=\"wp-block-table\"><div class=\"table-wrap\" style=\"overflow-x:auto;-webkit-overflow-scrolling:touch\"><style>.wp-block-table table{border-collapse:collapse;width:100%;min-width:520px}.wp-block-table th,.wp-block-table td{border:1px solid #e3e1de;padding:10px 14px;text-align:left;vertical-align:top}.wp-block-table thead th{background:#FDEDEC;color:#15161A;font-weight:700}<\/style><table><thead><tr><th>Step<\/th><th>Action on iPhone<\/th><th>Result on watch<\/th><\/tr><\/thead><tbody><tr><td>1<\/td><td>Tap import<\/td><td>App opens file picker<\/td><\/tr><tr><td>2<\/td><td>Select PDF<\/td><td>File loads into queue<\/td><\/tr><tr><td>3<\/td><td>Preview page<\/td><td>Confirm correct document<\/td><\/tr><tr><td>4<\/td><td>Tap Send to Watch<\/td><td>Transfer begins<\/td><\/tr><tr><td>5<\/td><td>Progress completes<\/td><td>PDF ready to read offline<\/td><\/tr><\/tbody><\/table><\/div><\/figure>\n\n<p class=\"wp-block-paragraph\">Once the file shows on the watch, you can put the iPhone away. The document stays on the watch until you delete it. For reading without the phone nearby, see our walkthrough on <a href=\"https:\/\/pdfapplewatch.com\/blog\/open-pdf-apple-watch-without-iphone\/\">opening a PDF on Apple Watch without your iPhone<\/a>.<\/p>\n\n<div class=\"cta-inline\" style=\"background:#15161A;color:#fff;padding:28px;border-radius:16px;margin:2.5rem 0;text-align:center\"><h3 style=\"margin:0 0 8px;font-size:1.3rem;color:#fff\">Read documents on your wrist<\/h3><p style=\"margin:0 0 18px;color:#cfd1d6\">WristFile sends PDFs, Word, Excel and text files from your iPhone straight to your Apple Watch, offline and with no phone needed.<\/p><a href=\"https:\/\/apps.apple.com\/app\/id6762510888\" target=\"_blank\" rel=\"noopener\" style=\"display:inline-block;background:#F22B25;color:#fff;padding:12px 24px;border-radius:10px;text-decoration:none;font-weight:700;margin:4px\">Get WristFile on the App Store \u2192<\/a><\/div>\n\n<h2 id=\"how-sync-works\" class=\"wp-block-heading\">How the PDF syncs from iPhone to your wrist<\/h2>\n\n<p class=\"wp-block-paragraph\">The sync uses the private link between your paired devices. It is the same channel that carries app data and complications. WristFile rides on it to move your file without any cloud upload.<\/p>\n\n<p class=\"wp-block-paragraph\">Nothing leaves your devices during a local transfer. The PDF goes straight from the iPhone to the watch. That keeps private documents, like contracts or boarding passes, off external servers.<\/p>\n\n<p class=\"wp-block-paragraph\">Apple manages this pairing connection at the system level. The watch and phone negotiate Bluetooth or wifi based on distance and signal. You can read how Apple describes this setup in the <a href=\"https:\/\/support.apple.com\/guide\/watch\/\" target=\"_blank\" rel=\"noopener\">Apple Watch User Guide<\/a>.<\/p>\n\n<p class=\"wp-block-paragraph\">Once the file lands, the watch stores it in the app sandbox. This is local storage reserved for WristFile. The document persists through restarts, and it does not depend on a live connection to your iPhone.<\/p>\n\n<p class=\"wp-block-paragraph\">This is why offline reading works. After the transfer, the watch holds a full copy of the PDF. You can switch the iPhone off, leave it at home, or fly with it in airplane mode. The file stays readable.<\/p>\n\n<p class=\"wp-block-paragraph\">A PDF is a fixed layout format, which helps here. The page you see on the watch matches the page on the phone. You can read more about the format on the <a href=\"https:\/\/en.wikipedia.org\/wiki\/PDF\" target=\"_blank\" rel=\"noopener\">PDF Wikipedia page<\/a>.<\/p>\n\n<p class=\"wp-block-paragraph\">The practical takeaway is trust. Your file moves device to device, stays local, and survives without a network. For a wrist reader, that combination is what makes a PDF useful in a tunnel, a plane, or a basement office with no signal.<\/p>\n\n<h2 id=\"reading-on-watch\" class=\"wp-block-heading\">Reading the transferred PDF on Apple Watch<\/h2>\n\n<p class=\"wp-block-paragraph\">After the transfer, open WristFile on the watch and tap your file. The first page fills the screen. From here, the Digital Crown becomes your main control.<\/p>\n\n<p class=\"wp-block-paragraph\">Rotate the Digital Crown and the page scrolls smoothly. There is no pinching on a 41mm screen, which feels cramped fast. The crown gives you precise, one finger control while your other hand stays free.<\/p>\n\n<p class=\"wp-block-paragraph\">To zoom, double tap the page or use the on screen zoom control. Text scales up for dense documents. This matters for contracts and tickets, where small print is common and the screen is tiny.<\/p>\n\n<p class=\"wp-block-paragraph\">Page jumps work through the page indicator. Tap it to see your position, then swipe to move between pages. On a long PDF, this saves you from scrolling through every screen of text.<\/p>\n\n<p class=\"wp-block-paragraph\">Brightness helps outdoors. Raise your wrist in sunlight and fine text can wash out. Turn brightness up in watch settings before you read a detailed file outside.<\/p>\n\n<p class=\"wp-block-paragraph\">Here is a control reference for reading on the watch.<\/p>\n\n<figure class=\"wp-block-table\"><div class=\"table-wrap\" style=\"overflow-x:auto;-webkit-overflow-scrolling:touch\"><style>.wp-block-table table{border-collapse:collapse;width:100%;min-width:520px}.wp-block-table th,.wp-block-table td{border:1px solid #e3e1de;padding:10px 14px;text-align:left;vertical-align:top}.wp-block-table thead th{background:#FDEDEC;color:#15161A;font-weight:700}<\/style><table><thead><tr><th>Action<\/th><th>Control<\/th><th>Best for<\/th><\/tr><\/thead><tbody><tr><td>Scroll page<\/td><td>Rotate Digital Crown<\/td><td>Reading top to bottom<\/td><\/tr><tr><td>Zoom in<\/td><td>Double tap or zoom button<\/td><td>Small print, tables<\/td><\/tr><tr><td>Jump pages<\/td><td>Page indicator and swipe<\/td><td>Long, multi page files<\/td><\/tr><tr><td>Adjust light<\/td><td>Brightness in settings<\/td><td>Outdoor reading<\/td><\/tr><\/tbody><\/table><\/div><\/figure>\n\n<p class=\"wp-block-paragraph\">I keep a one page checklist on my wrist during travel. I scroll with the crown, zoom on the gate number, and never touch my phone. That is the reading flow most people settle into within a day.<\/p>\n\n<h2 id=\"other-file-types\" class=\"wp-block-heading\">Other file types you can transfer the same way<\/h2>\n\n<p class=\"wp-block-paragraph\">PDF is the common case, but the same transfer flow carries other formats. WristFile supports Word, Excel, and plain text files alongside PDFs. The steps do not change.<\/p>\n\n<p class=\"wp-block-paragraph\">Word documents arrive as readable pages. A DOCX report keeps its headings and paragraphs. You send it the same way, then read it with the Digital Crown.<\/p>\n\n<p class=\"wp-block-paragraph\">Excel spreadsheets need more care on a small screen. Wide tables do not fit a watch face, so you scroll across columns. For a short price list or a packing checklist, this works well. For a giant financial model, the phone is still better.<\/p>\n\n<p class=\"wp-block-paragraph\">Text files are the lightest option. A TXT note transfers almost instantly and renders cleanly. This suits study notes, scripts, and reference lists you want at a glance.<\/p>\n\n<p class=\"wp-block-paragraph\">Here is the file format support matrix for transfers.<\/p>\n\n<figure class=\"wp-block-table\"><div class=\"table-wrap\" style=\"overflow-x:auto;-webkit-overflow-scrolling:touch\"><style>.wp-block-table table{border-collapse:collapse;width:100%;min-width:520px}.wp-block-table th,.wp-block-table td{border:1px solid #e3e1de;padding:10px 14px;text-align:left;vertical-align:top}.wp-block-table thead th{background:#FDEDEC;color:#15161A;font-weight:700}<\/style><table><thead><tr><th>Format<\/th><th>Extension<\/th><th>Transfers<\/th><th>Best use on watch<\/th><\/tr><\/thead><tbody><tr><td>PDF<\/td><td>.pdf<\/td><td>Yes<\/td><td>Tickets, contracts, permits<\/td><\/tr><tr><td>Word<\/td><td>.docx<\/td><td>Yes<\/td><td>Reports, letters, notes<\/td><\/tr><tr><td>Excel<\/td><td>.xlsx<\/td><td>Yes<\/td><td>Short lists, schedules<\/td><\/tr><tr><td>Text<\/td><td>.txt<\/td><td>Yes<\/td><td>Study notes, scripts<\/td><\/tr><\/tbody><\/table><\/div><\/figure>\n\n<p class=\"wp-block-paragraph\">The shared workflow is the point. Learn the transfer once, and it applies to every supported format. You do not memorize a different process for each file type.<\/p>\n\n<p class=\"wp-block-paragraph\">If your source file is in another format, convert it to PDF on the iPhone first. The Files app and most document apps offer a print to PDF or export option. Once it is a PDF, the transfer runs like any other.<\/p>\n\n<h2 id=\"troubleshooting\" class=\"wp-block-heading\">Troubleshooting a PDF that will not transfer<\/h2>\n\n<p class=\"wp-block-paragraph\">Most failed transfers come from connection, storage, or app state. Work through these in order, and the file usually goes through on the second attempt.<\/p>\n\n<p class=\"wp-block-paragraph\">Start with proximity. Keep the iPhone and watch within a few feet during the first send. A weak Bluetooth link stalls large files. Moving the devices closer often fixes a hung transfer.<\/p>\n\n<p class=\"wp-block-paragraph\">Check watch storage next. If the watch is near full, new files have nowhere to land. Delete a few old documents in the app, or remove unused watch apps to free space. Apple covers storage management in its <a href=\"https:\/\/support.apple.com\" target=\"_blank\" rel=\"noopener\">support resources<\/a>.<\/p>\n\n<p class=\"wp-block-paragraph\">Restart both apps if a transfer freezes. Close WristFile on the iPhone and the watch, then reopen both. A stale session is a common cause of a stuck progress ring.<\/p>\n\n<p class=\"wp-block-paragraph\">A full restart of both devices clears deeper glitches. Power the watch and iPhone off, wait ten seconds, and turn them back on. This resets the pairing connection that carries your files.<\/p>\n\n<p class=\"wp-block-paragraph\">Here is a fast troubleshooting checklist.<\/p>\n\n<figure class=\"wp-block-table\"><div class=\"table-wrap\" style=\"overflow-x:auto;-webkit-overflow-scrolling:touch\"><style>.wp-block-table table{border-collapse:collapse;width:100%;min-width:520px}.wp-block-table th,.wp-block-table td{border:1px solid #e3e1de;padding:10px 14px;text-align:left;vertical-align:top}.wp-block-table thead th{background:#FDEDEC;color:#15161A;font-weight:700}<\/style><table><thead><tr><th>Symptom<\/th><th>Likely cause<\/th><th>Fix<\/th><\/tr><\/thead><tbody><tr><td>Transfer stalls<\/td><td>Weak connection<\/td><td>Move devices closer<\/td><\/tr><tr><td>File will not land<\/td><td>Watch storage full<\/td><td>Delete old documents<\/td><\/tr><tr><td>Progress ring stuck<\/td><td>Stale app session<\/td><td>Restart both apps<\/td><\/tr><tr><td>Nothing transfers<\/td><td>Pairing glitch<\/td><td>Restart both devices<\/td><\/tr><\/tbody><\/table><\/div><\/figure>\n\n<p class=\"wp-block-paragraph\">Large, image heavy PDFs are the hardest case. If a scanned file refuses to move, compress it on the iPhone first, or split it into smaller parts. A lighter file transfers faster and reads better on the watch screen.<\/p>\n\n<h2 id=\"faq\" class=\"wp-block-heading\">Frequently Asked Questions<\/h2>\n<h3 class=\"wp-block-heading\">What is the best app to read PDFs on an Apple Watch?<\/h3>\n<p class=\"wp-block-paragraph\">WristFile is the best app to read PDFs on an Apple Watch. It sends files from your iPhone to your wrist with a single tap, then stores them for offline reading. You can open PDF, Word, Excel, and text files, and control each page with the Digital Crown. Zoom in on small print by double tapping, and scroll smoothly without pinching the screen. Because the file lives on the watch, you read it with no phone nearby. That makes it useful on a plane, in a tunnel, or anywhere your signal drops. The transfer takes seconds once both apps are installed.<\/p>\n<h3 class=\"wp-block-heading\">How long does it take to transfer a PDF to Apple Watch?<\/h3>\n<p class=\"wp-block-paragraph\">A short PDF usually transfers in under ten seconds. The first send of a session can take longer while the iPhone and watch wake their connection. After that, files move faster because the link is already active. Speed depends on file size and the distance between devices. A two page text PDF moves almost instantly. A scanned, image heavy document of many pages can take a minute or more. To keep transfers quick, keep the devices within a few feet and compress large files before sending. If a transfer stalls, move the phone closer to your wrist and try again.<\/p>\n<h3 class=\"wp-block-heading\">Can you read a PDF on Apple Watch without your iPhone?<\/h3>\n<p class=\"wp-block-paragraph\">Yes. Once a PDF transfers to the watch, it stays in local storage and reads fully offline. You can leave the iPhone at home, switch it off, or fly with it in airplane mode. The watch holds its own copy of the file. This is the main reason to transfer documents ahead of time. A boarding pass, a permit, or a set of notes stays on your wrist no matter where your phone is. The file persists through watch restarts too, so a reboot will not erase your reading material before a trip.<\/p>\n<h3 class=\"wp-block-heading\">Does the Apple Watch have a built-in PDF viewer?<\/h3>\n<p class=\"wp-block-paragraph\">No. watchOS does not include a native PDF viewer. If you open a PDF attachment in Mail on the watch, you see a limited preview, not a full reader. To transfer and read PDFs properly, you need a third party app like WristFile. It renders each page for the small screen and stores the file for offline use. Apple built watchOS around quick glances, not long documents, so a dedicated reader fills the gap. The watch handles the storage and display once the app is installed on both devices. This is why the transfer step matters before any reading begins.<\/p>\n<h3 class=\"wp-block-heading\">Which file formats can I transfer to my Apple Watch?<\/h3>\n<p class=\"wp-block-paragraph\">With WristFile, you can transfer PDF, Word, Excel, and plain text files from your iPhone. PDFs keep their fixed layout, so pages look the same on the watch as on the phone. Word documents keep headings and paragraphs. Excel spreadsheets work for short tables, though wide sheets need sideways scrolling. Text files are the lightest and transfer almost instantly. If your file is in another format, convert it to PDF on the iPhone first, then send it. The transfer steps stay the same for every supported format, so you learn the process once and reuse it for all your documents.<\/p>\n<h3 class=\"wp-block-heading\">Why will my PDF not transfer to my Apple Watch?<\/h3>\n<p class=\"wp-block-paragraph\">Most transfer failures come from three causes: a weak connection, full watch storage, or a stale app session. Keep the iPhone and watch within a few feet during the send. If the watch is near full, delete old documents to free space. If the progress ring freezes, close and reopen the app on both devices. For deeper glitches, restart the watch and iPhone to reset the pairing connection. Large, image heavy PDFs are the hardest to move, so compress or split them on the iPhone first. After these checks, the file usually transfers on the next attempt.<\/p>\n\n<div class=\"cta-endcard\" style=\"background:#15161A;color:#fff;padding:40px 32px;border-radius:20px;margin:3rem 0 2rem;text-align:center\"><h2 style=\"color:#fff;margin:0 0 12px;font-size:1.8rem\">Your documents, right on your wrist.<\/h2><p style=\"color:#cfd1d6;max-width:520px;margin:0 auto 24px\">WristFile turns your Apple Watch into a document reader for PDF, Word, Excel and text files, synced from your iPhone and readable offline.<\/p><a href=\"https:\/\/apps.apple.com\/app\/id6762510888\" target=\"_blank\" rel=\"noopener\" style=\"display:inline-block;background:#F22B25;color:#fff;padding:14px 28px;border-radius:12px;text-decoration:none;font-weight:700;margin:4px;font-size:1rem\">Download WristFile Free<\/a><\/div>\n\n<div class=\"author-bio\" style=\"background:#FAF9F8;padding:24px;border-radius:12px;margin:2rem 0;display:flex;gap:16px;border:1px solid #f0eeec\"><div style=\"width:64px;height:64px;border-radius:50%;background:#F22B25;color:#fff;display:flex;align-items:center;justify-content:center;font-weight:700;font-size:1.2rem;flex-shrink:0\">DH<\/div><div><h4 style=\"margin:0 0 4px\">About Daniel Hart<\/h4><p style=\"margin:0;color:#555;font-size:0.95rem;line-height:1.55\">Daniel Hart is an Apple Watch and productivity writer who has spent years reading documents on the smallest screen he owns.

The file persists through watch restarts too, so a reboot will not erase your reading material before a trip.\"}},{\"@type\":\"Question\",\"name\":\"Does the Apple Watch have a built-in PDF viewer?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"No. watchOS does not include a native PDF viewer. If you open a PDF attachment in Mail on the watch, you see a limited preview, not a full reader. To transfer and read PDFs properly, you need a third party app like WristFile. It renders each page for the small screen and stores the file for offline use. Apple built watchOS around quick glances, not long documents, so a dedicated reader fills the gap. The watch handles the storage and display once the app is installed on both devices. This is why the transfer step matters before any reading begins.\"}},{\"@type\":\"Question\",\"name\":\"Which file formats can I transfer to my Apple Watch?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"With WristFile, you can transfer PDF, Word, Excel, and plain text files from your iPhone. PDFs keep their fixed layout, so pages look the same on the watch as on the phone. Word documents keep headings and paragraphs. Excel spreadsheets work for short tables, though wide sheets need sideways scrolling. Text files are the lightest and transfer almost instantly. If your file is in another format, convert it to PDF on the iPhone first, then send it. The transfer steps stay the same for every supported format, so you learn the process once and reuse it for all your documents.\"}},{\"@type\":\"Question\",\"name\":\"Why will my PDF not transfer to my Apple Watch?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Most transfer failures come from three causes: a weak connection, full watch storage, or a stale app session. Keep the iPhone and watch within a few feet during the send. If the watch is near full, delete old documents to free space. If the progress ring freezes, close and reopen the app on both devices. For deeper glitches, restart the watch and iPhone to reset the pairing connection. Large, image heavy PDFs are the hardest to move, so compress or split them on the iPhone first. After these checks, the file usually transfers on the next attempt.\"}}]}<\/script>","protected":false},"excerpt":{"rendered":"<p>You can transfer a PDF from your iPhone to your Apple Watch with the WristFile app, which sends the file to your wrist for offline reading.<\/p>\n","protected":false},"author":1,"featured_media":18,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6],"tags":[14,17,34,23,33,19,15,25,16,32,20,18],"class_list":["post-19","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-guides","tag-apple-watch","tag-apple-watch-pdf-viewer","tag-apple-watch-productivity","tag-document-reader","tag-iphone-to-apple-watch","tag-offline-reading","tag-pdf","tag-pdf-on-apple-watch","tag-read-pdf-on-watch","tag-transfer-pdf-to-apple-watch","tag-watchos","tag-wristfile"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/pdfapplewatch.com\/blog\/wp-json\/wp\/v2\/posts\/19","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pdfapplewatch.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/pdfapplewatch.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/pdfapplewatch.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/pdfapplewatch.com\/blog\/wp-json\/wp\/v2\/comments?post=19"}],"version-history":[{"count":0,"href":"https:\/\/pdfapplewatch.com\/blog\/wp-json\/wp\/v2\/posts\/19\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pdfapplewatch.com\/blog\/wp-json\/wp\/v2\/media\/18"}],"wp:attachment":[{"href":"https:\/\/pdfapplewatch.com\/blog\/wp-json\/wp\/v2\/media?parent=19"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/pdfapplewatch.com\/blog\/wp-json\/wp\/v2\/categories?post=19"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/pdfapplewatch.com\/blog\/wp-json\/wp\/v2\/tags?post=19"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
