More apps in testing, same privacy promise. Every one of these processes data entirely on your device.
Sievr
Photo Cleanup

Substrata
Health Intelligence
Discovers how your environment affects your health. Sound, pressure, weather — correlated with your HealthKit data.
Intuii
Daily Estimation Puzzle
Fermi estimation meets confidence calibration. How well do you know what you don't know?
Sirrius
Pet Health
Your pet's health records, meds, and vet visits — tracked by on-device AI that never sends their data off your phone.
The Promise
Privacy isn't a feature. It's the architecture.
Every app follows the same rules
- All data processing happens on your device — not "mostly" on-device, entirely
- No user accounts. No sign-ups. No email collection. Open the app and start using it
- No analytics SDKs, no tracking pixels, no fingerprinting. We don't know who you are
- AI features use Apple's on-device models. Your data never hits a server
- One-time purchases or optional subscriptions. Free tiers are fully functional, not crippled demos
- Delete the app and everything goes with it. There's nothing on our end to delete
