A timer that survives restarts.
Turn fasting on in Settings, pick a goal from 1 to 168 hours and start a fast. The timer keeps running when the app closes, history is editable, and a goal notification is optional.
- Off by default. Ayuvo never infers a fast from missing meals
- Summary shows a Fasting card only while a fast is active
- Quick Log widgets offer Start fast and End fast, and food logging pauses while a fast is active

A goal, a tap and a reminder.
Set a daily goal in millilitres or fluid ounces, log a glass in one tap or a custom amount, and add reminders. The Drink ring appears on Summary only when water tracking is on.
- Water progress on the Apple Watch and in widgets
- Hydration has its own charts from day to year
- Water entries travel inside your food diary export

What fasting and water send, and to whom
Both features are local.
Timers, goals and history are stored on the phone and are never written to Apple Health or Health Connect.
Reminders are scheduled locally on the device.
Water and fasting settings and fasting sessions move between iPhone and Android in Export All Data.
