Cal AI is a calorie tracking app founded in 2024 by Zach Yadegari and Henry Langmack. It grew quickly as one of the best known AI health apps.
Users take a photo of their food and the app estimates the calories, protein, carbs and fat. Barcodes and food labels can also be scanned, and meals can be logged by text. Cal AI sets daily goals from the user's age, weight, height and target, and tracks progress over time with weight logging and charts.
