How to sync Book Tracker across iPhone, iPad, and Mac

One of the most common questions users ask is: “How do I sync my Book Tracker library between devices?”

Book Tracker uses Apple’s iCloud service to keep your books, reading progress, notes, and statistics updated across iPhone, iPad, and Mac — without the need to create an account.

How to enable iCloud sync on iPhone and iPad

  1. Open the Settings app on your device.
  2. Tap your Apple ID at the top.
  3. Select iCloud.
  4. Scroll to the Apps using iCloud section and tap Show All.
  5. Find Book Tracker in the list and make sure the toggle is ON (enabled by default).

How to enable iCloud sync on Mac

  1. Open System Settings.
  2. Click your Apple ID in the sidebar.
  3. Select iCloud.
  4. Scroll to the list of apps.
  5. Find Book Tracker and make sure it’s enabled.

Things to know about iCloud sync

  • Same Apple ID required → You must be signed in with the same Apple ID on all devices.
  • Automatic sync → Once enabled, changes you make (adding a book, updating progress, adding a quote) appear on all devices after a short delay.
  • No extra account needed → Sync works entirely through iCloud, so you don’t have to register or log in separately.
  • Privacy first → Your library is stored in your private iCloud account. Book Tracker never has access to your data.

Troubleshooting iCloud sync

If your devices don’t sync correctly:

Best practices

  • Always confirm iCloud is enabled before adding books on a new device.
  • Open the app on all your devices regularly to keep the sync active.
  • Make a manual backup before troubleshooting sync problems, so your data is safe.

✅ With iCloud sync enabled, Book Tracker automatically keeps your entire library and reading history updated across iPhone, iPad, and Mac.
