Great device needs a better app

Got my i5 plus for $16. The device is really nice, blows away competitors which costs 8-10x more. But this app is really crappy. Very basic features, not much to configure, no friends connection, and it appears to be always disconnected, maybe that's part of the reason why the battery lasts so long. Most laughable feature is the the gps sports, it only picks up one spot every 5 minutes or so and connect the dots with straight lines! The sleep monitor's accuracy is also dubious, only a few large periods of deep and light sleeps. My Fitbit records a lot more movements during sleep. Overall, this app needs a major update, I doubt we will get it though. I would be more enthusiastic to recommend to my friends if this app is a bit more decent.

The Worst App in the History of Apps

I don't think I have ever hated anything as much as I have hated this app. If I could give it 0 stars, I would. It is truly, truly terrible. I decided to "turn off" notifications for phone calls, texts, etc. through this app. Or so I thought. While the app gives you the option to do so, it does not actually stop the notifications from appearing on your watch - rendering this part of the app completely useless. Even when I erased the app, I was STILL getting notifications to my watch. They only way to stop them from coming through was by turning off Bluetooth. Since you need the app in order for the watch to work, I am returning the watch as this app has caused far too much frustration. It's not worth it. Don't get the watch. Don't get the app. Save yourself hours of frustration and money. Just don't get it.

Good device, bad app

The device is great, affordable and really useful. But the app needs a lot of improvement. I personally think there should be and option where you get the notifications on the devide only when your phone is locked or something similar, so you wont be getting all the texts in your smart watch. Also, whenever i get a text and it shows in the watch, it's always missing the last letter. For example, if someone texts me and says "im here", i'll show up as "im her"
