Pen Library for tiptoi

Manage the books on your tiptoi pens directly from your Android phone.

Connect a compatible pen using a USB data cable and adapter, choose its folder, and explore your library. No charging-station Wi-Fi or personal account is needed.

• Browse and search the German book catalog, with publisher book details and covers when available.
• Download audio to your phone for reuse, or keep it only temporarily during transfer.
• Install missing files with integrity checks and verification by reading the copied file back.
• Remove books you no longer need. A verified backup stays on your phone for offline restoration.
• Sort pen files by size or reported modification date. File dates are not playback history.
• Name several pens, inspect saved inventories when disconnected, and review shared or individual book selections before adding missing files.
• Delete individual phone copies or clear downloaded audio and backups with explicit confirmation.

Your library, profiles, selections and backups stay on your phone. No ads, analytics or application server. Catalogs, covers and audio are requested directly from Ravensburger. The interface is available in English, German and French; the catalog and book audio currently shown are German.

Requires Android 8 or later, USB storage support and a compatible tiptoi pen that exposes USB mass storage. Tested so far on a fourth-generation pen. Charging-only cables will not work. Keep the app open during transfers. The app does not play book audio on the phone. Uninstalling it or clearing its storage erases phone downloads and backups.

Try the clearly labeled, read-only demo library without connecting hardware.
