In terms of functionality, there is no difference between the MapMyFitness apps. You will be able to record any type of workout using any of the apps or sites. You can use your username and password from an existing account to sign into any of our other sites and apps, so there's no need to create a second account. Your MVP membership, workouts and all other data will transfer no matter what MapMyFitness app you use.
The main difference between the free apps and sites is that each is catered toward an individual audience and will provide nearby and recommended maps based on that app's user base. For instance, using MapMyRun will provide nearby running routes others have recorded, while MapMyRide will provide nearby routes for cyclists.
The main difference between the free and paid app is that the paid app includes three distinct features: an ad-free experience, and an integrated camera for pausing to take photos. Occasionally, the paid app is on sale or free for promotional periods on the app stores. Be sure to keep an eye out for these!
For clarity's sake, the MapMyFitness paid apps do not entitle you to the features of our MVP membership. To read more about the MVP features be sure to explore the Help Center, or blog post Are YOU Ready for the MVP Experience?
