Vow
An AI coach that keeps your promises with you.
Coming soon to theApp Store
About the product
Vow turns habit-building into something you can feel: a living orb at the center of the app grows brighter as you keep your vows and dims when you drift. It reaches deep into the OS (FamilyControls and ManagedSettings to actually block distracting apps, HealthKit signals for sleep and activity, streaks and reminders) while an OpenAI layer plans your week, checks in, and adapts to how you really live. I built the server side too: Firebase Auth, Firestore, Cloud Functions for the AI orchestration, FCM push, and hand-written security rules hardened with App Check.
Role
