The app provides some useful information for helping to find the right location for the two Cel-Fi devices, more than just the number on the front panel. Unfortunately, it's extremely difficult to get connected to my Duo, as it constantly seems to say I'm out of range despite being halfway between the transmitter and receiver boxes. Once it fails, it won't connect again until I force close this app and try again. Either way it's also EXTREMELY slow to connect, so prepare to set aside 10+ minutes just to find the device. When it does finally connect, it will stay connected for the duration the app is open, unless you move out of Bluetooth range. Then it'll break and you won't get back in until you force close the app. Again. The app has a function to enable/disable which bands/tech are boosted, but this does not work for me. It either breaks the Duo completely, requiring both boxes to be reset, or causes the booster to alternate between working and "overload/failure" mode. I'd love for it to only boost 4G and not 3G since that is unusable here, but it doesn't work.

It worked fine for me when I used it to view settings of the booster. I did not try to make changes or update anything because it's owned and managed by the cellular provider and because it said my software was already up to date. The app let me see which bands were being boosted and gave more details of signal strength which was interesting to see, but counting the bars on my cellphone was all I needed to do to confirm it was working correctly.

I'm not sure why there are so many complaints about this app. I have had NO issues whatsoever in pairing this with either my Tab S4 or my Galaxy S10 and there are no issues maintaining a connection. You're able to see exactly which bands are being boosted as well as the strength, quality, etc., and determine whether you have enough separation. You can even change bands being boosted. There is TONS of technical info. Bars are NOT enough! Now we're able to use mobile broadband as our internet.
