MyFitnessPal

MyFitnessPal is a leading digital health platform, primarily developed as a mobile application and website for nutrition and exercise tracking. Originally launched in 2005 by Mike Lee, the brand began as a personal project before evolving into one of the world's most popular health informatics tools. Throughout its history, the platform has undergone significant ownership changes, shifting from an independent startup to a major corporate asset.

In 2015, athletic apparel giant Under Armour acquired MyFitnessPal for $475 million to bolster its "Connected Fitness" ecosystem. However, in 2020, Under Armour divested the brand, selling it to the private equity firm Francisco Partners for roughly $345 million. Since then, the platform has focused on expanding its AI capabilities, including the 2026 acquisition of the viral photo food logging app Cal AI. Today, the software is developed and maintained by a global team of engineers, with its primary corporate operations based in the United States.
