About this app

Lose weight the simple way, with intermittent fasting that actually fits your life. FastBurn turns fasting into a one-tap habit: start your timer, watch your body shift into fat-burning, and see the results add up day after day.
Built for people who want real transformation without complicated diets or calorie counting.

ONE-TAP FASTING TIMER
Start and stop your fast with a single tap. A clear visual countdown shows exactly how long until your eating window—no math, no guesswork.

PROVEN FASTING PLANS
Choose the schedule that fits you: 16:8, 18:6, 20:4, or OMAD. New to fasting? FastBurn recommends the right plan based on your goals and experience.

SEE YOUR BODY CHANGE
Watch your weight trend drop on a clean progress chart. Log every entry and finally see the line move in the right direction.

BODY-STATUS ZONES
As you fast, FastBurn shows the stage your body is in—fat-burning, ketosis, and autophagy, so every hour feels like progress.

BUILD AN UNBREAKABLE STREAK
Complete daily fasts to grow your streak and unlock badges at 3, 7, 14, 30, 90, and 365 days. A little accountability goes a long way.

STAY HYDRATED
Track your water intake alongside your fasts to feel your best while you burn.

Start your transformation today, your first results are closer than you think.
