Was okay. Now awesome!

Okay here's something awesome.

I posted a 2⭐️ review because I felt this app was missing an important feature.

The developer added the missing feature, and found me on Twitter to let me know about it. It now does everything I want. And I wish I could give more than 5⭐️!

Great App!

I purchased this app a few weeks ago to help with my workouts. It lacked a feature that I found necessary for my workouts. I emailed the developer with my concerns and he returned my email!!! He also emailed me advising me that my concern has been resolved!! I'm impressed by the developers integrity and follow through. The update resolved my concern!
