I like the concepts of this sensor and the app. BUT!!!!!! 1-The alarms are so LOUD that they wake up everyone in the house! 2-It keeps losing connection between the sensor and the phone! 3-In order for me to due anything on my phone involving the internet, playing a game or anything else I have to turn off the Bluetooth for these to work! I like the look of the app, it dose NOT meet my expectations, and it dose NOT match the description of the apps experience!
