The live calorie countdown on your wrist
Your day starts at zero and burns down in real time. Eat and it jumps. Move and it falls faster. One number, always ticking, on your iPhone and your Apple Watch.

How it works
01
Midnight: zero
Set your daily burn once. From the moment your day starts, the clock ticks steadily down — wake up already in the green.
02
Eat: it jumps
Log your meal in two taps and watch the number leap up into the red — then start burning it back down.
03
Move: it falls faster
BurnClock reads your active energy from Apple Health, so a workout visibly speeds up the countdown into the green.
04
Beat your week
See exactly how today compares to this same moment on each of the last 7 or 30 days. Stay ahead of yourself.
