MyFitnessPal is a calorie counting and nutrition tracking app. Brothers Mike and Albert Lee founded it in 2005, and the app launched on phones in 2009. Under Armour bought it in 2015 and sold it to the investment firm Francisco Partners in 2020.
Users log the food they eat by searching a large database, scanning a barcode or entering their own recipes. The app counts calories, protein, carbohydrates, fat and other nutrients against daily goals. People can also log exercise and water and track their weight over time. MyFitnessPal connects with fitness apps and devices such as Apple Health, Google Fit, Garmin and Fitbit, so steps and workouts are added automatically.
The basic app is free with ads. MyFitnessPal Premium is a paid subscription that removes ads and adds features such as macro goals by meal, meal scan and planned meals, and barcode scanning moved behind the paywall in some regions. The app runs on iOS, Android and the web. It is one of the most used diet trackers in the US, the UK and Canada, and many dietitians ask clients to share their food diary from it.
