Tetr Notes

Tetr is a handwriting app that saves your notes as ordinary files in a folder you choose. Most note apps lock your handwriting inside their own storage. Tetr does the opposite: every note is saved into your own iCloud Drive folder as a standard PNG image, together with a Markdown text file transcribed from your handwriting on-device. Your notes are readable by any app, on any platform, today and in twenty years. WRITE NATURALLY - Endless vertically scrolling canvas — just keep writing, the page grows with you - Built on the same ink engine as Apple's own apps: low-latency, pressure-sensitive Pencil strokes with palm rejection - Full tool picker: pen, pencil, marker, eraser, ruler, and colors - Light and dark mode — ink adapts on screen, files stay dark-on-white YOUR FILES, YOUR FOLDER - Pick any folder in iCloud Drive, or let Tetr create its own visible folder - Notes save automatically…
