## What is FastTam?

A tracker built for fasting and nothing else. See when you didn't eat — and how deep that stretch actually went — on one screen.

Built for you if you
• want to keep a routine like 16:8 going
• run 24, 48, or 72-hour fasts and want them staged
• would rather log fasting hours than calories or meals
• want fasting and weight in the same view

■ Fasting timer
14:10, 16:8, 18:6, 20:4, OMAD, or a window you set yourself. Run it once, or keep it as a repeating routine.

■ Ketone Boost
Separate 24, 48, and 72-hour targets, with the stage you're in right now.

■ A log read by ketone depth
The weekly timeline colors each fast by ketone depth rather than length. A fast and the eating window that follows it sit in one capsule, so the shape of the day is right there.

■ Monthly heatmap
A month of ketone activity in a single view. Tap through for what each tier means.

■ Weight
Log your weight the moment a fast ends. Your goal weight and recent trend are read together, so you know which way things are going.

■ Fasting coach
Short, time-aware guidance on the home screen for wherever you are in the fast.

■ Fasting guide
Six common mistakes, plus the safety signals that mean stop.

■ Live Activity and widgets
Time remaining on the Lock Screen, in the Dynamic Island, and in a home screen widget. Start and end notifications included.

■ Share your month
Turn a month of fasts into a card image and share it.

■ iCloud sync
Your log carries across devices on the same Apple Account.

Ads can be removed with a one-time purchase.

[Disclaimer] This app does not provide medical advice. Talk to a professional before starting a fast or changing your diet. If you are pregnant or nursing, or have diabetes or a history of eating disorders, consult a doctor first.
