User Reviews/Opinion:

• This app works fine and it gave the technical data fine… but the cell locations are inaccurate, the information it shows while technically correct is wrong, mapping doesn’t work. Traveling with the app does nothing towards updating the map. There are better apps for the information you can get from it. If the mapping was accurate it would be worth it, but every tower I looked at is in the wrong location and the app cannot update the map or location on the map. I tried the app again, it is s battery hog and doesn’t allow the screen to fully dim and still does not give accurate tower locations
• You do not need access to my contacts nor to make phone calls! Uninstall since I cant use it. I have way too many spam calls using unique names in my contacts tricking me sorry not risking it.
• Not showing cell towers. Shows little green squares along our road where other cell strength maps display red. Red agrees with my experience as our area has very poor signal. Buying a Samsung signal booster for Verizon . Otherwise 1 or no bars here.
