Tenikki is a handwriting-only diary. There is no keyboard — anywhere. Just write the day in your own hand. ■ No keyboard There is no text-input UI at all. Nothing stands between you and writing. ■ One page a day One entry per day. Nothing is finalized automatically when the date changes, so you can keep adding later. Confirm by hand when you're done. ■ Three pens, three colors (free) Choose a ballpoint, pencil, or fountain pen. The pencil shades with pressure; the fountain pen varies its line. Write in black, red, or blue, in fine, medium, or thick. Eraser, undo/redo, and pinch-to-zoom included. ■ Sync across iPad & iPhone (free) Automatic sync via iCloud. Write on iPad, look back on iPhone. ■ Gentle reminders Get a reminder at your chosen time only on days you haven't written yet. ■ Paper styles, image sharing, and app lock (free) Choose ruled, grid, or blank paper. Share a full day as one image. Lock the app with Face ID, Touch ID, Optic ID, or your device passcode. Your first PDF export is free. ■ Pro (one-time purchase) • Remove ads • Unlimited PDF exports (split into pages by date) • Color picker (any color) A fixed, paper-like background and ruled lines keep the look identical across devices and in PDF. Ink colors stay true even in Dark Mode. Make the feel of handwriting a daily habit.
