Sweatmeal vs Cal AI
Cal AI counts calories from a photo of your food. Sweatmeal answers a different question: how much you should eat today, given the training a wearable measured.
Facts about Cal AI were read on its public pages on 2026-10-15. Features and prices change, so check www.calai.app before you decide.
What is Cal AI?
Cal AI is a calorie tracker where you snap a photo, scan a barcode or describe a meal to get calories and macros.
- Lets you "snap a photo, scan a barcode, or describe your meal" to get calorie and nutrient information.
- Lists the App Store and Google Play; its FAQ mentions iPhone and Android and Apple Health for iPhone.
- Its FAQ says "CalAI is about 80% accurate" and that values can vary.
- Offers a 3-day free trial.
- Acquired by MyFitnessPal (announced March 2026, per news reports); the Cal AI app was reported to remain independent.
The differences
| Criterion | Cal AI | Sweatmeal |
|---|---|---|
| Approach to the target | Calculates calories and macros for what you log | The day's calorie and macro target moves with the training you did, read from a wearable; deficit or surplus is cycled around training load |
| Training data | Apple Health on iPhone, per its FAQ | Whoop, Oura, Strava, Ultrahuman and Apple Health |
| AI coach | Not described on its homepage | AI coach that names your next meal (Pro) |
| Logging | Photo, barcode or a description of the meal | A line of text or a photo, through the coach (Pro) |
| Stated accuracy | About 80%, by its own FAQ | Photo and text logs are estimates; trend and wearable data keep the target honest |
| Platforms | iPhone and Android | iPhone today |
| Free tier and trial | 3-day free trial | Targets, wearable sync, trends and race calendar are free; logging and the coach are Pro, with a 7-day trial on the annual plan |
Sweatmeal is on iPhone today. Its Pro price is shown in the App Store in your own currency before you are charged.
Who is it for?
Cal AI suits you if
- Your main friction is logging and you want the fastest way to estimate a meal from a photo.
- You want a simple calorie and macro counter without training integration.
Sweatmeal suits you if
- You train hard and want the daily number to change with the session, not stay fixed.
- You use Whoop, Oura, Strava or Apple Health and want that data to set the target.
- You would use the coach to decide the next meal, and treat photo logging as a convenience rather than the point.
How Sweatmeal works
Sweatmeal reads your training from Whoop, Oura, Strava, Ultrahuman or Apple Health, sets the day's calorie and macro target from it, and never drops the target below your resting metabolic rate. Protein is set from lean mass, and your burn estimate is refined from your weight trend. The full calculation is on the methodology page.
