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!

Just finished the last workout. The app itself works well on my phone, I've never had it glitch or not play. The GPS does not work at all though. For a free app it, it was excellent. The workouts did their job, I went from never running 8 weeks ago to being able to run a 5k today so I am very happy. The first 4 weeks are really easy going and then week 5 and on are a steep increase. The app also expected me to be running 10 minute miles at week 5 and I'm still not doing that after 8 weeks.

My previous rating was 5 stars, it functioned well as a free timer for simple run/walk intervals to help you get back into shape. now you have to pay for a subscription past the first four days. I don't want a subscription with whatever other "upgrades" exist. i was okay with hearing an ad or two in exchange for an easy to follow run schedule. If I wanted to pay for fitness I would have paid to join a gym. I'll be switching to a free running app in the future
