Every other fasting app points at the scale. FastFocus is about what fasting does for your mind.
FAST FOR FOCUS, NOT FOR THE SCALE
Track your fast on a clean instrument dial and watch your body move through its stages - from fed state to the 14h focus window many fasters describe as their sharpest hours.
MAP YOUR PERSONAL FOCUS WINDOW
While fasting, log one-tap clarity check-ins ("how sharp do you feel right now?"). FastFocus builds your personal clarity map: your self-reported focus, hour by hour into the fast. Most people discover a repeatable peak - then start placing deep work inside it.
EVERYTHING INCLUDED
- Clarity map: your focus score by fasting hour
- Personal focus-window alert, timed to your own data
- AI coach: personalized plan, mid-fast urge SOS, auto daily brief, weekly report and debrief
- Body meter: live kcal, liver-glycogen and fat-burn estimates by fasting hour, with a timeline chart and milestone alerts (population-average estimates, information only)
- Menu scan: photograph a restaurant menu and get three dishes worth ordering plus one to skip, ranked by how long you have fasted
- Fuel log: a photo, a menu pick or a typed line becomes a calorie and macro estimate, with a protein baseline and meal-vs-clarity patterns. No counting, no weight goal
- Sharp Score: your week in one number
- Streak with automatic freeze protection
- All protocols: 14:10, 16:8, 18:6, 20:4 and custom hours
- Full history and trends
STAGE NOTIFICATIONS
One ping when the focus window opens, one when you hit your fasting goal, and an optional evening reminder to start. No spam.
Scan features send the photo or text you choose to our service and a third-party AI service for the estimate. You are asked in the app before the first one is ever sent, every meal can be logged by hand instead, and photos are never stored.
SIMPLE, TRANSPARENT PRICING
Weekly and yearly subscriptions, or a one-time lifetime purchase. Prices are shown upfront. Subscriptions renew automatically unless canceled at least 24 hours before the end of the period - manage or cancel anytime in Settings. No hidden trials.
FastFocus provides general information about fasting physiology, not medical advice. Individual experience varies. Consult a doctor before fasting if you have a medical condition, are pregnant, or are under 18.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Start where you already are.
- Setup now asks whether you are already fasting and since when, so the timer picks up from your last meal instead of zero. Not fasting yet? Skip it and start from the Fast tab.
- See your alerts before you allow them: the notifications page previews the focus-window, goal and evening alerts at your own times, and asks for permission only when you tap to turn them on.
