User reviews

Basic but useful

I have used this at various points over the last few years. Definitely helped with stamina and overall speed. Started using it again and it does not seem to sync with Apple Health / Fitness apps despite having all permissions to do so. Can I presume this app is no longer being developed / supported?

Amazing

I absolutely love the app and really recommend it. I found it super helpful for my running and has improved my stamina massively!

Can’t listen to music on your phone and get notifications for when your next set is up.

Wouldn’t recommend

Response from developer

Hi Mariam Thank you for highlighting this gap. The app has been recently updated and now supports music from other apps while exercising. This includes the ability to hear notifications while music is playing - these can also be silenced in the Settings page. I am actively working on improving the app, I hope you will return to using it again and do let me know if there are any other features or changes you would like to see. Best regards Richard

At last

I’ve been waiting for an app like this for ages. It’s perfect for bringing some structure to my run/walk exercise.
