NISTIS PRO — PAY ONCE IF YOU LIKE IT • Lifetime unlock: one payment, yours forever. (Monthly and annual also available — but you never need them.) • Wear OS app with a tile and complications: start, end, and adjust a fast from your wrist. Works alongside the phone app — install Nistis on your phone and open it once. • Advanced stats: monthly and yearly trends, completion rate, average fast length • CSV and JSON export, plus import from other fasting apps • Extra accent colors PRIVATE BY DESIGN No account. No analytics. No tracking. The only network connection this app ever makes is to Google Play for purchases. Your fasting history lives on your device and exports any time. The stage timeline shows general information commonly associated with fasting — it is not medical advice.
