Calorie Burndown
Track your calorie deficit, built on HealthKit.
Calorie Burndown tracks a daily calorie deficit (or surplus) goal against what HealthKit already knows you've eaten and burned — no duplicate manual logging, just your existing Health data turned into one clear number: how much room you have left today.
Works everywhere you do: an iPhone app with an iPad-optimized layout, a home screen widget, a watchOS companion app with real-time numbers even without your phone nearby, and watch face complications.
