So far it's been a good timer to use alongside my other run tracker. It's getting me off the couch and back on the road so I'm thankful to the developers of this app. Only complaint is it doesn't resume your workout if it gets closed for whatever reason. Twice now the app has closed during a run and then reopened has lost all progress of the current run. It's annoying when it happens but not a deal breaker

Actual running is fine, been using it on and off for about a year but I used to be able to use my own music playlist. You'd have to pay for their mixes. Now I can't even access my own music from within the app without paying. I can use my own playlist from my normal media app but it's annoying.

I've been using this app on and off for about 2 years and taken by itself it's excellent. However, the app has recently been demanding unnecessary permissions like my precise location. It can be denied, but it asks at the beginning of every workout. Also, the app has become increasingly insistent that I register. It asks every time I turn the app on and today it even turned off my music and my ability to view C210K as it opened up my browser and redirected me to a registration page.
