What the Intermittent Fasting Tracker actually does

The Intermittent Fasting Tracker pins a daily fasting window to a live timer you can glance at, and keeps a record of what you have actually done. Twelve presets are built in grouped by difficulty — from 12:12 up to 23:1 — plus a custom window in one-hour increments.

Two modes are supported:

• Flexible ("Start Now") — tap to begin a fast after your last meal; the end is computed from your window length.
• Daily Schedule — pin the eating window to fixed clock times (for example 12:00–20:00). The cycle repeats automatically each day.

Your chosen schedule, mode, and clock times persist across app restarts, and an active session is reconstructed from the start time whenever you reopen.

What you see during a session with the tracker

A timer shows your current elapsed and remaining time (toggle which direction you read), the current phase — fasting or eating — and your eating window boundaries.

Plans change: Eat Early lets you close a fast before target as a one-time exception or a permanent shift. Fast Early ends the eating window ahead of schedule. Completed and cancelled sessions from the last 30 days stay in your history.

Notifications are opt-in per account — when enabled, they remind you at key moments in your schedule.

How to use the tracker

In the bottom navigation bar, the fasting badge updates every second with your current phase and time remaining — the eating window shows in a warm color, fasting in the default. That one-second glance is often all you need to decide whether you can start eating yet, without opening the full tracker.

Pick a window you can actually repeat for a few weeks, let the schedule run, and only adjust after you have a week of clean data.
