Handwriting note-taking app for Android tablets (Honeycomb). A key design goal is quick response to pen strokes and 100% vector graphics. Developed on a Lenovo ThinkPad Tablet.
Features: * Active pen (digitizer) support on ThinkPad Tablet, HTC Jetstream and HTC Flyer. * Very fast response to pen strokes. * "Fountain pen" mode supports pen pressure data, more pressure = thicker line (requires active pen) * Pinch-to-zoom. * Double-finger tap to zoom. * Two-finger move gesture. * Pen strokes are vector art, zoom does not pixelate your writing. * "Pen only" mode (optional) disables touch input while writing. * Android 3.x hardware accelerated graphics. * Open source (GPL), so your notes are not stuck in an opaque file format. * PDF export (save to SD card, Evernote, Share). * PNG (raster image) export. * Can backup/restore your data. * Ruled/Quad background paper * Tagging for pages so you can group them together. * Switch between multiple notebooks. * Undo/redo.
The n-trig active pen has been tested on the ThinkPad Tablet, HTC Jetstream, and the HTC Flyer (Honeycomb). The basic functionality should work on any Android tablet, but distinguishing pen from finger data and pressure sensitivity might not work on others. Please let me know your results if you try it on another tablet. See also http://code.google.com/p/android-quill/wiki/SupportedDevices
