The last version doesnt work any more, it crashes again and again on the splash screen, I cant sync my device. The app has really bad interface, has no good statistics. The main issue is the synchronization, during it you always get unexpected result such as your daily statistics is rewritten, or one week and half of your trainings is missed, or it doesnt sync at all or any surprises. Common guys, you have really big company and manufacture really cool product, but you have no money for modern and pretty good app? Your app really is sucks, please copy and port jawbones app at least, your current app is foolishly. Guys just read all feedback of your customer and just stop torture people, who bought your products.
