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
