Bluetooth turns itself on – JBL Music Review

Hi developers, I like this app! It allows to me to be able to hear what’s playing on my iPad so much better!! However, I have a question for you: Why does the Bluetooth turn itself on? I have gone to the settings for my iPad and turned it off several times. And then powered off my iPad. Each time the Bluetooth is automatically turned back on when I power up my iPad. Why? I know assuming is not always the smart thing to do, BUT, I assume that if something is set to off when the iPad is powered off it should remain off until I turn it back on. My irritation is because having the Bluetooth on all the time runs the battery of the iPad down very quickly! Please help me to understand why this happens.
