Photo calorie app Cal AI, downloaded over a million times, was built by two teenagers

Zach Yadegari and Henry Langmack, both 18-year-old high school students, co-founded Cal AI, an app that logs calories and macros by analyzing pictures of food. Despite their young age, they have achieved significant success, with over 5 million downloads in eight months and $2 million in revenue last month, according to Yadegari. While TechCrunch couldn't verify these claims, the app boasts high ratings on both the Apple App Store and Google Play. Cal AI leverages large image models from Anthropic and OpenAI, and is trained on open-source databases, achieving 90% accuracy in food recognition. The app's development involved overcoming technical challenges, such as recognizing ingredients in complex dishes.

Yadegari, who previously sold a gaming website for $100,000, met co-founder Blake Anderson through social media. The team, including COO Jake Castillo, operates out of a hacker house in San Francisco. Despite the intense startup environment, Yadegari plans to attend college, valuing the experience over the typical Silicon Valley dropout path. Cal AI now employs eight full-time staff, including developers, a designer, and social media managers, as they continue to grow their business.
