I am now able to run 5 km, 3 days a week, because of this app. When I started, I could barely run for 30 seconds without pain, but now I can run for 30 minutes continuously without any pain. C25K is a great app and an excellent program to follow for improving your fitness and building healthy running habits. I highly recommend it to every beginner runner. I have also opted for the Pro version, which has been a great addition to my experience.

This app was great. 2 years ago. Now it doesn't work without GPS (no, I don't want it to track my location, it's an app built around timing, it doesn't need that), and more importantly, the settings that are supposed to allow you to turn off its background data collection/cookies can't be turned off. Sure, the option is there, but if you opt out, exit the screen, and then come back, mysteriously all permissions have been granted again. So no. I'm not keeping this app. It's now a leach.

Thanks for your feedback. GPS is required for calories/distance, GPS map route, and more accurate voice alerts to prevent OS from killing a background app. We’d like to know details of the issue you mentioned. Please send the details or screenshot to [email protected]. We'll pass it along to our development team for any way to improve.

I have never been fond of running, but since my health has turned a bit, I decided to start training for a 5K. This app has made it INCREDIBLY easy to build up to running the 3.1 miles of the 5K. I love its alerts, letting you know when to walk and when to run, and the "you have one minute left". It does have its days when it force closes, but they are rare. It also works well with Pandora. Love love love it!!! UPDATE: I heard the issue on 7-1 got fixed!! Yay!
