First running app I've stuck to!

I've used a lot of running apps. Pretty much all of them, however the simplicity of this one actually made me complete it. I started with the 5k, then moved up to this huge 42k app! I love the reward badges as well! Thank you!!

This app has some significant bugs

There are quite a few problems with this app. Firstly the program will jump to the end even with a simple hard stride - this has happened over and over - if my iPhone is in my running pocket or an arm band iPhone holder. The other major problem is that if I’m on a 150 program the app timer gets stuck and will not stop running so for instance a 150 minute program can run on for 5 hours. These 2 problems need to get fixed ASAP.

1st Marathon

I used the 5k app to start running again after several years and the 21K app to train for my 1st half marathon. Loved both. Kept me motivated and on track. Bought the 42k to train for my first marathon. Highly recommended.
