User reviews

Poor customer support

Wow your customer service folks have a bit of an attitude about them. Time to stop using the app.

LOVE

Great functionality and excellent price. Reliable app, easy to use.

Great customizable features if you don’t need to listen to any other audio source while you run

Major flaw is not being able to listen to any audio sources while you run. You won’t get any notifications of interval changes, either haptic or audio notifications.

Love this app!

This turned out to be just what I was looking for. I can customize it or use the suggested intervals. It was super cheap for the paid version and it was totally worth it because they aren’t trying to charge you a monthly fee to keep using the app, which I thought was pretty sweet!

Amazing App!!!

Very straightforward to use and provides really helpful data for workout.
