Original name: Kiroku - AIがひとこと返す日記アプリ
A diary app where just one line a day is enough. Write and AI will return comments.
Automatically translated from Japanese by AI
I realized that the reason diaries don't continue is because there's too much to write. Kiroku limits input to just one line and a single mood emoji.
When you write one line, AI returns a comment based on that day's content. The calendar fills with color on the days you write, making you feel the continuity. The mood score transitions become a graph, helping you notice changes in your state.
If something comes back even when you just write "I'm tired today" and close it, you'll feel like opening it again. Rather than increasing the amount of records to keep going, I designed it with the idea that the key is creating a reason to open it.
Tech stack: Flutter / Firebase (Firestore, Cloud Functions, Auth) / RevenueCat. AI comment generation happens on the Cloud Functions side, and API keys are not exposed to the client.
