Utter trash

Save yourself the time. Slow, buggy and so paywalled you can’t even see if the app is worth the 70-90 dollars this dev wants for it. I’ll use tea leafs on the wind before shelling out a penny to this piece of garbage.

Don't Bother

App doesn't work and too much money wanted for a subscription of a app that doesn't work

Does not work

Far To Expensive so avoid it….

No 5G towers displayed.

The towers that do show haven’t been updated since 2021.

Junk

Downloaded this app to help with finding the direction to our only cell tower from my remote country work location. It’s a very rural area and I know there’s only one tower. The app showed literally a hundred towers of varying strengths and ranges. They were sprinkled randomly across the map with many of them being actually out in the ocean. There was no tower shown on the map anywhere near where the only tower is actually located. In my opinion this is just an app created to get you to pay their subscription for even more tower locations. It’s useless and completely inaccurate. User beware!
