User reviews

Intervals and splits

Precise split times and I may create my own run interval workouts with ease and the voiceover feature is immaculate. It announces my running pace for the pre defined interval and distance covered. Allows me to accurate track progress quantitatively.

Best running app out there

I’ve been searching the App Store for a running app that has the basic features for free, it felt like mission impossible. Not only are the basic features free, it’s incredibly simple to use and works. You need more than the basics? You can purchase more for a one time fee that’s reasonable rather than an absurd monthly subscription. I’m brand new to running, this app helped me get off the couch. Overall 15/10

Great for outside intervals

Easy to set up and adjust. Also works great from the Watch app while you’re out running.

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.
