Very problematic App

I saw the number of reviews warning me that this app may not work well (but a few positive ones too). It had many features I wanted so I thought Id give it a try. I have been wearing a fitness band for over two years with no issues. I recently received an Apple Sport Watch and wanted all the sleep monitoring features I have been used to. In almost a week of use, I was only able to get sleep tracking data for two nights. Setting the watch to sleep mode often took a number of tries. On the successful nights I was pleased with the report and information. On three other nights, I would wake up and not be able to set the watch to "awake". Apparently I had somehow "canceled" the sleep app during the night. Save your money and try another app. I found the app very difficult to use (says to press firmly to set into sleep mode - have to push hard in a very tiny space. But some how it could be cancelled seemingly with as I lay down???).
Apple Watch desperately needs a decent sleep App!!
