iOS (iPhone / iPad)

is free on the App Store for iPhone and iPad; it needs iOS and iPadOS 17 or later. When you sign in with the same Account (Apple, Google or email), the library, marks and plan are shared with Android and quillo.tr.

Library, reader, listening (device voice, natural Piper voice, Cloud), markup, notes, excerpts, translation, study cards, export, Account and Google Drive sync are the same as on Android; text recognition is done with Apple Vision. The design is the same too: date and greeting on Home, the quick capsule, "Where you left off", the glass bottom capsule and the Ai orb; the glass dock in the reader. The free/paid line is the same: only the cloud voice and Ai are paid (Starter / Pro), everything else is free. The document scanner (with Apple's document camera), QR and barcode reading, PDF tools, letterhead-signature-stamp, the Ai balloon, voice mode and personal memory are on iPhone too. The differences are small: only files can be shared from another app (no plain text or link sharing), voice notes are not written into the PDF as audio attachments, audio files are saved as M4A, and instead of "Other cloud folder" there is manual backup and restore in Settings › Sync. For a document opened from Files, you go back with the system's "◀ Files" link. Pro is bought with an App Store subscription.
