I do not know where to start. Before the upgrade, the app was always sketchy. Sometimes it worked, sometimes it didnt. Syncing was always a "press and pray" adventure. After the upgrade and one replacement watch later, nothing works. The watch was frozen for two weeks. After an hour on the phone, tech support was stumped so they sent me a replacement watch. Now the watch fails to record data and spins endlessly try to connect or sync. At an easy running pace, the watch showed my heart rate at my maximum heart for a sprint. It is shameful that Mio actually released this product. I am convinced Mio did zero beta testing. I have a $169 piece of junk and useless app.
