Ratings and reviews

this app is good, still seems in early stages but makes the coach to catcher comm so simple and affordable. way more intuitive than anything else. and the best part is their team, they've been over the top helpful as I tested out their app and ran into a few issues on my end along the way! they've definitely earned our business and we look forward to more great seasons with them

No sound at all, doesn't work with Powerbeats Pro 2

worked fine for trial now headset will not work when I join a channel. Tried with different headsets and once I join a channel audio goes to the phone. headset with with all other apps. will need a refund of this doesn't resolve itself. already lost use in a whole tournament this weekend.
