I've used this app two or three times in past years to start running or restart after a long break and enjoyed it. I downloaded it again to start running again after stopping for 2 years and now everything after the first week requires a premium subscription. Ew. There's too much bloat and extra that I don't want and won't pay for, but there's no option to access the workouts without all the rest and the subscription price. Off to find a new running app!

This used to be a great app until they added too much slop to the UI (which block you from even running it if your connection is spotty) and have now paywalled basic features. I just want a 5K running plan that I can track and I can't even do that anymore without paying a premium. Just switched to the "Just Run" app and it delivers exactly what I want without the bloat. So I recommend that.

It's a good app, but a few annoying things. if you are offline you cant basically use the app, and it wont recognized your membership even if you pay, that's annoying particularly if you want to use it in a hike without much cell service.... also if you accidentally close the app before the running timer runs out it wont register your run and you will need to restart it from 0...
