The Best AI Calorie Counter Apps for iPhone in 2026
Updated October 3, 2026. We make TrackAI, so read this knowing that; we say where another app is the better pick. Ratings and in-app purchase prices are from the US App Store on October 3, 2026. TrackAI's price is from October 28, 2026, when its subscription came back. Prices change and vary by country, so check before you buy.
Calorie counting used to mean searching a database for "chicken breast, grilled, 150 g" five times a day. AI changed the first step: you take a photo or type a sentence, and the app fills in the numbers. What still separates the apps is what they charge for that, what else they track, and how easy they make it to fix a wrong guess.
The short answer
- You want photo logging and don't mind paying: Cal AI.
- You want the biggest food database and an Android option: MyFitnessPal.

- You want fasting and calorie tracking in one app: Yazio.
- You want meal plans and a polished design: Lifesum.
- You want photo logging, nutrient tracking and a coach in one plan: TrackAI.

Cal AI
Cal AI is the app most people mean when they say "AI calorie counter". You snap your meal and it returns calories and macros, with a large community and a polished onboarding. The core experience is a paid one. If budget is not a concern and you only want photo logging, it is a solid choice.
MyFitnessPal
The veteran. Its food database is the largest of any app here, it runs on Android and the web, and it syncs with almost every device. Meal scan, voice logging and barcode scanning sit in Premium. Pick it if you want the deepest database or need to move between platforms.
Lose It!
Lose It! has been a weight-loss tracker for over a decade and logs by photo, voice, barcode or search. It sets a daily calorie budget from your goal and keeps the interface simple. A good pick for people who want something proven and not much else.
Yazio
Yazio combines a calorie tracker with intermittent fasting plans and recipes. If fasting is part of your plan, having both in one app is convenient.
Lifesum
Lifesum leans on meal plans, diet programs and recipes, with photo and voice logging. It is free to download with limited features; most of what makes it Lifesum is Premium.
Foodvisor and SnapCalorie
Both are photo-first. Foodvisor adds nutrition programs and coaching; SnapCalorie focuses on estimating portions from the photo and also takes voice notes. Both are worth a look if photo accuracy is your main concern.
TrackAI
TrackAI is our app, and it is new: released in July 2026, so it has few ratings so far. Its case is simple: four ways to log, full nutrition and a coach in one subscription, weekly or yearly, and the yearly plan starts with a 3-day free trial.
- Four ways to log: photo, a typed description, barcode, or a photo of the nutrition label. Every value is editable, and you can correct a meal in plain words ("it was oat milk").
- More than calories: fiber, sugar, sodium, 13 vitamins and 14 minerals per meal, plus a Food Score from 0 to 100 for how wholesome the meal is.
- An AI coach that sees today's meals, goals and activity, suggests what to eat next and can log food or water for you.
- 500 recipes with full nutrition, and suggestions for the nutrients you are missing today.
- Water, weight, steps and workouts, with Apple Health sync both ways.
What it does not have: no Android or web version, no fasting timer, no social feed, and no dedicated voice logging (you can dictate into Describe with the iPhone keyboard). Its barcode database is smaller than MyFitnessPal's; when a product is missing, the label scan covers it.
How to choose
- Decide if you will pay. If not, the choice narrows to the free tiers of the database apps, which keep AI logging for paying members. If you will, use the free trials to compare.
- Log one real day in two apps. Breakfast, a packaged snack, a home-cooked dinner. You will feel within a day which one you will keep using.
- Check how easy fixing is. Every AI app gets some meals wrong. The one where correcting a portion takes two seconds is the one that stays accurate.

FAQ
Is there a free AI calorie counter for iPhone?
Few are fully free. MyFitnessPal, Lose It!, Yazio and Lifesum have free tiers for manual logging, with AI and premium features in a paid subscription. Cal AI, Foodvisor, SnapCalorie and TrackAI are built around paid plans; TrackAI's yearly plan starts with a 3-day free trial, which is enough to log a few real days before you pay.
Which calorie app is the most accurate?
For packaged food, any app that scans the barcode or the nutrition label gives you the label's numbers. For home-cooked and restaurant meals, every photo app is estimating, and portion size is the hardest part. The most accurate habit is to log with a photo, then fix the portion before you save.
Is Cal AI worth it?
Cal AI made photo logging popular and has a very large user base, so it is a safe pick if you are happy to pay. If you also want vitamins, minerals, a Food Score and an AI coach that sees your day in the same plan, TrackAI does that and starts with a 3-day free trial.
Is TrackAI the same as trackai.app?
No. TrackAI by Engcraft (App Store id 6778757380, "TrackAI: AI Calorie Coach") is a different app from "Calorie Counter: TrackAI" by Stellar Marketing AG at trackai.app.
