AI Macro Tracker
Read full descriptionHide full description
Looking up every food in a database is a chore, and an AI calorie count you can’t check is hard to trust. Macropass is an AI macro tracker that shows its work. Describe what you ate by text, voice or photo, see the ingredients and assumptions behind the estimate, and correct it in a sentence. WHO IT’S FOR Macropass is for people who want to keep an eye on calories and macros but stopped tracking because logging every meal took too much work. If you weigh your food and need figures that match the label, a database tracker may suit you better. LOG BY TEXT, VOICE OR PHOTO Type “protein pancakes with berries,” say it out loud, or take a photo with your camera or pick one from your library. You can add typed details to a photo and use up to 3 photos for one meal. With voice, you review the transcript before Macropass estimates anything. Previous and saved meals can be logged again from the same screen. CHECK THE AI’S WORK Every estimate lists its ingredients with portions and calories, the assumptions the AI made, and an uncertainty range on the calorie total. If something is off, type a correction like “It was 3 pancakes, not 4” or edit a portion yourself, and the estimate updates. You can still edit a meal after saving it. LOG FROM CHATGPT OR CLAUDE Connect ChatGPT, Claude or another MCP client and log meals into the same diary from a chat. Your assistant can read your goals, today’s diary and your history, and it can edit or delete meals. Connecting is optional. CALORIES AND MACROS, DAY BY DAY Macropass tracks calories, protein, carbs, fat, fiber and sugar. Your day summary updates against your targets as each meal lands. Set different calorie and macro targets for each day of the week, so training days and rest days can differ. Log your weight and see its history in Goals. Apple Health sync is optional and off by default. NO STREAKS, NO ADS Mark a day complete when you’re done. There are no streaks to keep up and no ads. Export your data or delete your account anytime from the You tab in the app. Using Macropass requires Macropass Pro, a monthly or annual subscription. Eligible accounts get a 14-day free trial on the annual plan; the monthly plan has no trial. The subscription renews automatically at the price and period shown before purchase unless canceled at least 24 hours before the end of the trial or current period. Manage or cancel it in your App Store account settings. On the purchase screen, you can turn on a reminder 2 days before the annual trial ends. Macropass is a general wellness tool, not a medical device. Nutrition estimates may be incomplete or inaccurate and do not provide medical advice.

Verdict
The clearest difference is ads: AI Macro Tracker at none against SickPredict™'s shown. AI Macro Tracker also leads on update cadence (weekly vs every 2 months). SickPredict™'s advantage is device support (3 vs 1) and iOS requirement (13.0 vs 18.0). On price and in-app purchases there is nothing between them.
