What is Cal AI?
Cal AI is a mobile calorie tracking app. Instead of entering foods by hand, you snap a photo of your meal, scan a barcode, or describe what you ate, and the app returns calories plus protein, carbs and fat. The homepage says it uses the phone's depth sensor to estimate food volume, which the AI then uses together with its food analysis.
In practice you can log meals quickly, add your own foods and recipes, connect the app to fitness products such as Apple Health or Google Fit so exercise and steps are tracked alongside food, and review portions visually. The company says results are roughly 80% accurate and recommends good lighting and a sharp, full-frame photo for best results.
