Scrawl Keyboard for Onyx

Joshua Pham

About this app

Scrawl is a handwriting input keyboard built for Onyx Boox e-ink tablets. Write naturally with the stylus and Scrawl converts your handwriting to text — right where you're typing.

Unlike standard keyboards, Scrawl gives you a full-screen canvas optimized for e-ink displays. Write at your natural pace with fountain or ballpoint pen styles, erase mistakes with the eraser tool, and commit text with a single tap.

What’s new

Canvas-only rendering reliability update.

- Removes the raw EPD/TouchHelper drawing path from Scrawl's runtime drawing pipeline
- Uses standard Android Canvas rendering for strokes, eraser, annotations, undo/redo, and toolbar interactions
- Improves reliability on Boox devices where native raw EPD rendering could interfere with the canvas or UI controls
- Keeps on-device Onyx HWR for handwriting recognition
