Ratings and reviews

Does not work with Google Pixel with Android 13 OS as of 3/30/23. My phone can pick up the device but will not connect at all. The programmer's LED lights up when I hit 'pair device' but then goes out and doesn't connect. I wish Whelen would go back to the old style programmer because this is total garbage.

Android Galaxy S23+ can see the device under available Bluetooth devices but app cannot see and will not pair to it. I don't have this problem with SoundOff ConfigureIT.

Doesn't connect to anything from our work phone. Could be an issue working with the Android interface but whatever it is causing this makes this app pointless
