How we build

Private by Design

Your photos, reading history and audio are processed on your device. Anything an app does send to a server is spelled out in that app's own privacy page.

E-Ink Native

Layouts, typography and page turns tuned for BOOX Palma and paper-like screens.

No Lock-In

Free to start. Where an app has Pro features, a one-time Lifetime purchase is always offered alongside any subscription.

Native Performance

Swift for iOS, Kotlin & Compose for Android. Fast starts and minimal battery impact.

Speech Timer

One timed block per speaker for team meetings — a name, a note, and green/yellow/red cues. Runs in your browser with no account; nothing leaves your device unless you choose to share a link.
