Your calorie budget is wrong. Let's fix it.
Missing resting calories in Apple Health throw off apps like MyFitnessPal and Lose It. Calorie Gap finds the gaps and fills them in.
You have a problem.
Apple Health tracks your resting energy hour by hour. But when you take your Apple Watch off at night, it sometimes fails to sync the estimated overnight calories back to Health. The result: missing hours that silently shrink your daily calorie budget.
The problem
5 hours of overnight calorie data are missing
Calorie Gap fixes it.
It scans your resting energy history, estimates what was lost during the missing hours, and writes the corrections back to Apple Health — so every app that reads your data gets your full burn.
The solution
Missing hours are filled by Calorie Gap
