Prepare while you are connected
Sign in and sync the material you want to study before going offline. Offline access requires an established, valid account context on the device; it is not a guest library.
Review locally, then reconnect
Review events are saved on the device before network transfer. The sync flow sends pending work when a connection returns and handles retries using the same event identity.
Know which actions need a connection
Source uploads, AI generation, purchases and account operations need connectivity. The browser application’s study flow is online; Android offline support does not imply equivalent browser offline behavior.
One design across screens
Android phone, tablet and web share the same visual system. The Android implementation has been exercised on emulators; a public Google Play listing and release verification are still pending.
