MyFitnessPal Acquires Teen-Built Viral Calorie App Cal AI in Strategic Move

Summary

MyFitnessPal has acquired Cal AI, a viral AI-powered calorie tracking app created by two high school students that achieved remarkable success with over 15 million downloads and $30 million in annual revenue in under two years. The acquisition, finalized in December 2025 after nearly a year of negotiations, brings Cal AI's seven-person team, including 19-year-old co-founder and CEO Zach Yadegari, under MyFitnessPal's umbrella while maintaining Cal AI as an independent product.

Cal AI differentiated itself through its simple, AI-driven approach to calorie counting, allowing users to estimate calories by taking pictures of food rather than manual entry. MyFitnessPal CEO Mike Fisher cited the impressive focus and dedication of the young founders as key factors in pursuing the deal, noting that despite their age, the team demonstrated serious commitment, including holding regular stand-up meetings on Sunday nights to accommodate their school schedules. The acquisition strengthens MyFitnessPal's position in a competitive market with approximately 70 rivals.

Following the acquisition, Cal AI has already been integrated with MyFitnessPal's extensive nutrition database, which includes 20 million foods, 68,500 brands, and meals from over 380 restaurant chains. This integration enhances Cal AI's capabilities while preserving its ease-of-use mission. Financial terms were not disclosed, though Fisher indicated the Cal AI team was satisfied with the offer despite not needing to sell. The retention period for the founders and team was not specified, though industry-standard terms typically range around four years.
