Calorithm — Log and Review Your Calorie Balance and Weight

Calorithm shows your calorie balance, the difference between what you eat and what you burn, by day, week, month, quarter, and year, from your meal, exercise, and weight records and Apple Health data. Logging and basic summaries are free.

See Your Calorie Balance in Charts
See calorie balance, intake and expenditure, weight, body fat, PFC, salt equivalent, steps, sleep, and water in daily, weekly, monthly, quarterly, and yearly charts, alongside the goals you set. Choose and reorder the cards you want to see.

Auto-Synced with Apple Health
Active energy, resting energy, weight, and body fat percentage are pulled from Apple Health each time you open the app. Steps, sleep, and water are read only if you allow it and are never written. Today's steps and last night's sleep are shown in the app and used in trend charts and Reports. The Water card shows how much you drank.

Log Meals and Exercise
Enter food names and calories by hand, or save meals and exercises you log often. You can also estimate calories with AI from a food name or a photo, and adjust the result with comments like "large size" or "extra cheese." Active energy for exercise can be estimated from its name and duration.

Daily, Weekly, and Monthly Reports
Reports summarize your records for each period without using AI. To look deeper, carry a report into Ask.

Ask About Your Records
Ask questions about your meals and exercise with record-aware AI consultation.

Home Screen Widget
Check today's balance from a widget without opening the app.

Meal Guidance Notifications
Set times for breakfast, lunch, and dinner to see how many calories are left for your next meal.

Dark Mode
Switch between light and dark appearance.

Your Data, Protected
Your health and food log data is stored on your device with AES-256 encryption. When you use AI features, only the input, photos, or record summaries needed are sent to AI services: Google for estimates and AI reports, OpenAI for Ask. Steps and sleep are sent only as summarized values, such as daily totals and nightly durations.

Not a Medical Device
Calorithm is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. Consult a healthcare professional before making medical decisions.
