I've used this app on and off three years. It doesn't do much except make me uncomfortable. These balloons have data points? What's a data point EXACTLY? No explanation. You cant be serious. Well okay uh what carrier? Cell ID? If youre going to show data being accessed by what appear to be devices, you should provide more info to the people whose data it is. Horseradish. MY CONCLUSION: it's a fake app tracked by state workers and their families stealing your info. Prove me wrong.

Maybe I am too dumb to use this app, but I found it incomprehensible for the basic task of trying to figure out which carriers have coverage in my neighborhood. I found the user interface to be needlessly complex, with no explanation about what the colors mean. I was also uncomfortable with all of the permissions that the app requires. Uninstalled after only minutes of use.

I use t-mobile and map shows pink color at my location. I assume that is a very poor signal since calls drop all the time. It would be nice if the app showed tower location. The app is definitely lacking, and I hope the next version is better.
