Features

Apple Health Sync: Get calories from Apple Health.
Calories/day: See your daily running average since a provided start date.
Calorie Countdown: Set a desired limit on your calories (e.g., 1,700 calories per day), and see how much time needs to pass before you can eat a certain amount (e.g., 500 calories).
Stats & History: Chart your daily totals over any range, and browse every tracked day.
