This is a fantastic free app - we started it last year but finished at the end of week 4 so we were determined to do it properly this time; and the interface is 100 times better!! Bar one day on W1, D2 where it had a total flip out, the app has always worked perfectly and I love the integrated music so I can listen to my playlist while running. While I won't be running marathons any time soon, I think the slow and steady approach has worked as I'm now running for nearly half an hour and even though I'm not that fast I haven't stopped once, nor is it as painful as it was a few weeks ago ;-) Thank you!!!

This is a review for the basic free app. As a basic application, it does just that - the basics. You press start and then tells you when to warm up, run, walk and cool down. There's no audio indication of which interval you are on or for how long that interval is. I also found (and this may be just me) that if I started the app and then switched to another to start music, then reopened C25K that I just got a blank screen and it would not display anything until the next interval.

Trying to use Galaxy Watch6 version of this. It is a struggle, it does not link with the Samsung Health app or the phone version of C25K app, but refuses to run at the same time as a workout on Samsung Health. It sometimes stops randomly. It stops Spotify from playing, and doesn't give an audio notification until 10-20 seconds after it is supposed to. You can't see what the time differences will be for the workout you will be doing. GPS and calorie tracking doesn't work sometimes. Rubbish.
