About this app

Your journal thinks, right there on your phone.

Write an entry. Koro automatically detects twelve emotional states, without you having to touch a thing, and indexes it by meaning, not just by keyword. Search for "the week everything felt heavy" and it appears, even if you never wrote those words.

Habits work the same way. Keep track of what matters, skip what doesn't. Weekly insights tell you which habit truly correlates with a better week, instead of you guessing.

What's included:
— Journal with automatic mood detection (12 states)
— Semantic search across all your entries: Memory tab, not a search bar
— Habit tracking with streaks and weekly correlations with mood
— Nine life areas, from Mental Wellbeing to Connection
— ​​Optional app lock (Face ID/fingerprint)

Everything runs on your device. No account, no cloud: nothing you write ever leaves your phone for anyone to read, not even us.

Free. No subscription, no paywall, no upsell screen.
Your diary right there on your phone. Mood detection, habit streaks.
