Calorithm — Your Calorie Balance at a Glance
Automatically syncs with Apple Health to track your calorie intake, expenditure, and balance in real time. Keep your diet on track with minimal manual input.
See Your Balance Instantly
View dietary energy, energy burned, and your net balance on a single dashboard. A progress bar shows how close you are to your daily goal.
Review Your Day on the Timeline
See all your meals, exercises, and weight entries in chronological order. Tap any entry to edit or delete it. A quick, clear view of everything you recorded today.
Auto-Synced with Apple Health
Active energy, resting energy, weight, and body fat percentage are pulled directly from Apple Health. Data updates every time you open the app.
AI Estimates Calories — and Active Energy
Just type a food name and AI estimates the calories. You can refine the result with comments like "large size" or "extra cheese." AI can also estimate active energy burned for exercises — just type the activity and duration.
Visualize Your Trends
Track calorie balance and weight changes across five time ranges — daily, weekly, monthly, quarterly, and yearly — with clear charts and goal lines.
One Tap for Favorites

Stay Motivated with Streaks
