About Kokoro
Kokoro is a quiet companion for the rhythm of your life. It reads your sleep, heart rate and movement, your calendar and free time, and a short daily check-in, then offers one good observation a week. Never a scoreboard, never a scold.
Everything stays on your device. There is no account and no cloud. Hana, the AI companion who writes your morning briefing and reads your week, runs entirely on your phone.
What you can do
- A three-tap daily check-in for mood and energy
- A morning briefing from Hana, written on device
- A day ribbon showing meetings, free pockets and where you are now
- Focus, workout and meditation timers, plus activity stopwatches
- Sleep, recovery, heart and movement in one place, with medications and vitals
- An Apple Watch app
How it’s built
- Phi-3.5 Mini running locally through llama.cpp
- HealthKit and EventKit read on device; nothing is uploaded
- iOS, watchOS, widget and Live Activity targets from one codebase
- Model loading moved off the main thread after an early launch freeze
