Snap a photo of your meal and get instant AI calorie and macro estimates.
Acquired — still operating
acquired by MyFitnessPal Mar 2026; runs independently
About
Cal AI is an AI-native calorie tracking app built around a single interaction: photograph your food and the app estimates calories, protein, carbs, and fat. It routes images through large vision models from Anthropic and OpenAI, tuned with retrieval over open food image and nutrition datasets, and the founders claim around 90% estimation accuracy on common meals.
The startup was founded in 2024 by teenagers Zach Yadegari and Henry Langmack and scaled unusually fast, reaching 15 million downloads and a reported $30 million in annual recurring revenue within two years. In March 2026 MyFitnessPal acquired the company after nearly a year of talks; the app continues to run independently and now draws on MyFitnessPal's 20-million-food nutrition database. It is the clearest example yet of an AI-first consumer app outpacing an incumbent on its home turf.
