Pro Tracks distance, duration, avg. speed, avg. pace, calories burned and hydration
Endomondo displays your route using Google Maps and tracks distance, duration, avg. speed, avg. pace, calories burned and hydration. It even tracks what music you listen to while exercising (can be viewed on their website).
Con Removed features from paying customers in the past
Endomondo used to be a singular priced upfront paid app with no subscription fee, twice. During the first restructuring, the app was changed on the store, leaving out the people who had paid originally, to then require them to pay again for the new app. After this happened, the app changed again to be free-to-play, dropping features that paying customers had paid for and locking them behind a monthly pay wall. So not only did long time users who paid for the app get ripped off once, if they had paid for the newer paid app, they got ripped off again when the app went free-to-play. This is not a great track record for the service, leaving to question, when is the next restructuring going to happen that may potentially take the money of paying customers without delivering the service promised.
Con Features locked behind paywall
Many features of the app are locked behind a monthly or yearly paywall. A single month subscription is $5.99, while the yearly subscription is $29.99. This may be prohibiting for those that want to track exercise, but do not want to commit to the cost.
