A fasting timer with a metabolic phase timeline, water and weight logging, and an AI scanner that reads a meal from a photo.
Fastive is our newest app. It keeps the core loop short — pick a plan, start the timer, log what matters — and works offline first, with no account required to begin.
The meal scanner estimates calories and macros from a photo using Google's Gemini API. Fasts appear on the iOS Lock Screen as a Live Activity and sync with Apple Health and Health Connect.
Fastive offers general wellness information and is not a medical device.
