Just works ok.

The app just works ok. I have an iPhone 6 and its still super laggy. The app also disconnects from the band during sleep after 2 hours. I wake up and it says it disconnected at so an so time. Its frustrating. So all of my sleep charts show I only had sleep for 2 hours. The only thing reliable is the alarm function. It does great.
