Feature

The app is amazing and everything works as intended. If possible can you make an update to the app so that it can work in the background. Currently if you start a speed test and open another app “coverage map” will pause until you reopen the app which defeats the purpose of features such as “smart” due to the fact that the app has to be open for all 500 tests.

The Best Speedtest App ever

This is by far the best Speedtest app ever and I love the community nature of the app (I have been using it I would probably say when Stetson first made it public on iOS)

Best cellphone coverage app out there

Coverage Map offers the most value in the cellphone space. Speed test results, plus signal coverage maps from Verizon, T-Mobile, and AT&T.
