Revisit your highlights and notes throughout the day. LeafTrove is independently developed by HoMade Works to organize and revisit your own notes. Note content comes first, with book titles and authors kept as source information. Download free and choose the sample library on the welcome screen to read, search, favorite and export without signing in, a computer or a reader. Sample text is original demonstration content. Keep notes on your home screen • Small, medium and large widgets, plus extra large on iPad. • Note excerpts take priority, with source book titles and authors. • Tap a widget to open the full note. Receive a daily reminder at your own pace • Choose a time to revisit a highlight or your own thought. • Tap a notification to open that same note. • Enable reminders and widgets separately. Control lock screen previews in system settings. Organize and share what you want to keep • Today's Reading selects from all notes, favorites or selected books. • Search titles, authors, highlights and notes. Read downloaded content offline. • Organize content with favorites, archive and review exclusions. • Shared text starts with the note, followed by its book title and author. • Export Markdown or JSON with note and source information. Two ways to bring back your notes USB local library: Export with the Mac or Windows helper 0.7.0, transfer the JSON to your iPhone or iPad and import it. Reading, widgets and reminders are free, without sign-in, subscription or automatic upload to our cloud. Export and import again to add new notes. The helper checks database fields before exporting EPUB/KEPUB text highlights and notes. PDF, handwriting and full books are excluded. Wi-Fi cloud library: Sign in with Apple and sync notes from a paired reader that meets setup requirements, then update the same library across iPhone and iPad. First-time setup requires an Apple silicon Mac with macOS 14+ or Windows 10/11 x64, and a data-capable USB cable. The helper and reader check model, firmware and tool state; some combinations currently cannot complete setup. Check the support page before starting a trial or subscription. Start sync manually on the reader, then refresh the app. Sync is not automatic or real-time. Helper downloads, current setup requirements and troubleshooting: https://homadeworks.com/apps/leaftrove/support/ USB export helper 0.7.0 is a separate preview. The formal Windows setup helper and USB export preview have different functions; follow the support page to choose. Cloud subscription and trial A monthly subscription enables new cloud sync and cross-device updates. Eligible users can try it free for one month. Apple shows the actual price, currency, eligibility and renewal terms before purchase. The trial renews automatically unless canceled in Apple subscription settings. Trials already started are not automatically extended. Downloaded notes remain available for reading, search and export after a subscription ends. USB local and sample libraries remain free. Each account includes 50 MB of cloud content storage and can link one reader at a time. LeafTrove does not provide an eBook store, full books or official reader services. Make sure imported, synced and shared content complies with applicable rights and terms. The app interface is in Traditional Chinese.
