What is Cal AI?
Cal AI is a mobile calorie tracking app for iPhone and Android that estimates calories, protein, carbs and fat from a photo of your meal. You can also scan barcodes, search a database of over 1 million foods or describe a meal. It suits people losing weight, bulking or tracking macros.
Manual food logging fails because weighing portions and searching entries for every meal takes too long. This app replaces most of that with a photo: it uses your phone's depth sensor to estimate food volume, then AI breaks the meal into calories and macros. The company says results are about 80 percent accurate, so it trades precision for a habit you will actually keep.

Frequently Asked Questions
Is Cal AI free?
No, not beyond the trial. You can start a 3-day free trial, but food scanning results require a paid subscription. Cancel through your iPhone or Google Play subscription settings, since deleting the app does not stop billing.
How accurate is Cal AI?
The company's own FAQ says it is about 80 percent accurate. Good lighting, keeping the food in focus and filling the frame improve results, and you can edit entries or scan barcodes for packaged foods.
Does Cal AI work with Apple Health?
Yes. On iPhone you connect Apple Health from the calories screen to import steps, and on Android you link Google Fit in the app settings. Data can take a few minutes to sync.
