MapMyFitness, the fitness app suite recently acquired by Under Armour, and MyFitnessPal, an online and app-based wellness tracking platform, have announced an integration, allowing users to sync data between the two platforms. MapMyFitness said in a statement that the integration was a much-requested feature.

Although it provides exercise tracking through integrations with apps and devices, MyFitnessPal has primarily been a diet tracking tool. In fact, according to the Apple Store's popularity rankings, MyFitnessPal’s free Calorie Counter & Diet Tracker is the most popular food tracking app on the Apple Store right now.

MyFitnessPal boasts some 40 million users and pitches its food tracking app as a fast and comprehensiveness of its database: ”The fastest and easiest-to-use calorie counter for iPhone,” the company claims in its app description, “with the largest food database of any iPhone calorie counter (over 3,000,000 foods) and amazingly fast food and exercise entry.”

MapMyFitness, meanwhile, says it has around 20 million users and focuses on GPS-based activity and exercise tracking for running, cycling, and walking. Now under the ownership of Under Armour, the company is pursuing an "open platform strategy", MapMyFitness general manager Chris Glode told MobiHealthNews last week, which includes integrating with over 400 different activity tracking devices.

That means that the integration introduces the option of calorie and nutrition tracking to MapMyFitness users, while MyFitnessPal users gain access to additional devices and features for tracking exercise. MyFitnessPal previously integrated with Fitbit, Withings, iHealth, Jawbone, Endomondo Sports Tracker, EveryMove, RunKeeper, Runtastic, Rhythm Pulse Monitor, Striiv Smart Play Pedometer and Digifit.

Under the integration, workouts recorded within MapMyFitness will automatically sync to a user's exercise diary on MyFitnessPal. This includes activity type, time, average pace and total calories burned. Users will still need to use MapMyFitness to access the activity feed or for other data, like route maps.

In August last year, we included MapMyFitness and MyFitnessPal in a roundup of similarly-named digital health companies. "Here’s hoping for a merger," I wrote at the time. "MapMyFitnessPal really rolls off the tongue."
