I have done a few beginning 5k run programs and this one is my favorite because it can be modified based on how the program is going for you. Some Couch to 5k apps really ramp up running time half way through and it can be too much too soon-esp if you are recovering from injury etc. This app asks you to rate the run based on your perceived exertion and will optimize following run based on you feedback. The app is also user friendly and the “coach” can be tailored to your preference level of encouragement or talking. Overall, I highly recommend this app!
