MyFitnessPal has grown its online fitness community to more than 30 million users. And now the company is launching a platform that will allow partners to build apps on top of MyFitnessPal for the first time.

San Francisco-based MyFitnessPal is launching its first-ever applications programming interface (API) so that developers can connect fitness measurement devices with a real-time database that provides nutrition information and other fitness tools. The move is part of a strategy to build an ecosystem of electronics that help people use devices such as smartphones or step counters to monitor their health and measure their physical activity. Many expect this movement to fuel broad growth in health and fitness apps over time.

Among the companies developing for it are companies that make devices for counting steps, measuring calorie intake, and other body patterns. The partners include BodyMedia, Finis Swimsense, Fitbit, Interactive Fitness, Striiv, Mio, Scosche Rhythm, Runtastic, Endomondo and Withings. With the partner integrations, MyFitnessPal users will be able to instantly sync their daily activities, weight, and body fat information from other health products directly with their personal MyFitnessPal food diary and exercise log.

MyFitnessPal has a database of nutritional information with more than 2 million listings. Those include the nutritional value of foods served at the most popular restaurants. The goal is to gather all the fitness data for a person in one place. MyFitnessPal has been growing at a rate of 1.5 million new users each month. To date, those users have reported that they have burned 88.8 billion calories and logged 12.6 billion minutes of exercise (almost 24,000 years).

“For the millions of people who have found success improving their nutrition with MyFitnessPal, we are now making it easier than ever to incorporate physical activity,” said Mike Lee, co-founder of MyFitnessPal. “We believe that by facilitating an ecosystem of the best-in-class brands and resources working together, we can help our users to more successfully accomplish their health goals.”

MyFitnessPal was founded in 2005 and it has 25 employees. Rivals include LoseIt!, WeightWatchers, and Livestrong. MyFitnessPal is bootstrapped. It was founded by brothers Mike and Albert Lee.

“Having a deeper understanding about fitness and health can motivate a person to change his or her behavior,” said Christine Robins, Body Media CEO. “Making it easier to see that information is a plus. By merging select data from our respective platforms, our partnership with MyFitnessPal will help consumers on their wellness journey.”
