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. Review Your Day on the Timeline See meals, exercise, and weight entries in order. Tap an entry to edit or delete it. Share as an Image Share cards from Trends and Reports as an image. Backup Back up your records and settings to a password-encrypted file, and restore them. 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.
