New Review & Updated since my last. With the onset of the paywall, I cannot recommend the app anymore. "User Experience" apparently means you have to pay. It was a great user experience before under the ad-supported model and really was a great app. It's hard to justify any pay-to-play model when the experience is the same under ad-supported. I will be deleting my data, and finding a new app, especially as now this only stands out as having a subscription, and has sold out.

Hi there. We apologize for any frustration you may have experienced with the change to a subscription model. We've added many new features to the app, but updated to a subscription model to provide the best value for our customers. I hope you can enjoy our app again in the future.

My experience with this app has been nothing short of awesome! 🏅🏆 I have accomplished so much more than I ever thought I could. However, I am currently locked out of the app. Not sure if it's a bug or something else. I know that I paid for the subscription. I'm not happy about this. I can't reach my destination without a map. Plus the play lists are awesome, but it overrides my other music apps most times when I get in the car, or plays over the music I'm listening to. 🙄

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.
