Ichinichi

什麼是 Ichinichi？

A daily journal built on creative constraints. One note per day — no folders, no tags, no decisions. Yesterday's notes become read-only, keeping you present instead of endlessly editing the past. End-to-end encrypted so you can trust it with your most private thoughts — not even we can read them. Runs entirely on your device as a PWA. No internet required. No account required. Open the app, start writing.
