R+2.0: device is AWESOME, app is INFURIATING
My five-star review is for the device — the Rhythm+ 2.0 is accurate, reliable, tough, comfortable, and I love it. It also syncs effortlessly with the apps I use (Strava and RideWithGPS) and records my HR there reliably, and it charges very easily because the strap is SUUUPER simple to remove completely. I love love it. The Rhythm Sync app, on the other hand, seems to serve no purpose whatsoever besides firmware updates. In the menu, the "Sync," "My Details," and "Configure Sharing" states are all grayed-out and I don't know why. I'd love it if this app served its own purpose and I could use it to further understand my stats, but in the meantime, here we are. But that does not affect my feelings about the Rhythm+ 2.0. So, five stars!
