Most AI health apps send prompts to a cloud. Vityss Ask is an on-device AI health advisor and AI wellness coach. It uses Apple Foundation Models on your device, grounded in your Apple Health and logs. No account for AI. No prompt history on our servers. We have no servers for your health. Unlimited Ask conversations are part of Vityss Pro. Wellness insights only, not medical advice.
Vityss reads Apple Health read-only and computes your scores on your device and Apple Watch. Your health data, audio and location never leave your device. The only thing sent off-device is optional, anonymised crash and usage diagnostics. Never your health data, name, scores, audio or location.
Vityss offers wellness insights, not medical advice. Its scores are not a diagnosis and should not be treated as final. Always consult a doctor about your health.
Daily Brief, last night's sleep and optional logging stay free. Vityss Pro unlocks the deep end. Price is shown in your App Store currency before you pay.
The live listing is Vityss โ Sleep, Stress & HRV. An Apple Watch unlocks the full Daily Brief. Phone-only still works for logging, journal and many insights.
