Viterbi Ink: Infinite Canvas

EliasCorp

About this app

Viterbi Ink is a stylus-first drawing and note-taking app built around one idea: ink should feel instant.

Draw, sketch and write by hand on an infinite, infinitely-zoomable canvas with ultra-low-latency wet ink that keeps up with your pen. Choose from a full set of brush instruments - pen, pencil, fountain pen, marker, highlighter and more - each responding to pressure and tilt.

- Infinite canvas: pan and zoom without limits
- Low-latency ink that feels natural to write and sketch with
- 12+ brush instruments with pressure and tilt
- Import and annotate PDFs
- Organize your work in nested folders
- Works fully offline - your canvases stay on your device

Built for Android tablets and phones with an active stylus, including the Samsung S Pen.

What’s new

- Keep dense-canvas raster budgets stable while drawing layers are composited and invalidated.
- Reduce unnecessary layer thumbnail and count work during active canvas input.
- Tighten spatial-grid hit testing and immediate eraser feedback, including docked PDF interactions.
- Extend the cube loading treatment across long-running workflows so progress has one consistent visual language.
- Refine the cube silhouette with a subtle rounded outline shared across all three faces.
