Nice. I've been using Jefit for Android but your UI looks better.

For Garmin devices the Gym Genius app appears to have similar functionality but I haven't actually tried it yet. https://www.geniuswrist.com/GymGenius/About

Thanks. Honestly, I didn't even know that Garmin offered an SDK to build apps. Will have to build a Riker app for the Garmin's too :)
