Track Your Calorie Deficit. Stay on Target.
The Deficit helps you stay focused on fat loss by visualizing your daily and monthly calorie balance. It pulls data from Apple Health, combining your calorie intake (logged using apps like Yazio, MyFitnessPal, or others) and calorie burn (from Apple Watch, workout apps, etc.) to show you the real picture.
- See your true calorie deficit day by day
- Track your weight change against your personal monthly goal
- Stay motivated with an Apple Watch app and live complication

The Deficit doesn’t replace your food or fitness tracker — it enhances it. If you’re already logging meals and moving with purpose (and with Apple Watch), this app brings it all together in a simple, powerful overview.
