The new version seems to be working very good with the Bluetooth. However I cannot get it to stop running in the background and killing my iPad battery. I have closed the app on my iPad but it continues to run and drain the battery down.

So this new version now can work with Bandhelper without any problem?

How did you realize that the app is running and draining the battery when you've closed it? Let me know and I'll try to fix it.
