### 1/5 — Utter trash

*2025-08-13*

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.

### 1/5 — Don't Bother

*2025-08-12*

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

### 1/5 — Does not work

*2025-07-19*

Far To Expensive so avoid it….

### 1/5 — No 5G towers displayed.

*2025-07-18*

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

### 1/5 — Junk

*2025-07-16, version 1.3.11*

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!

### 2/5 — Waste of time

*2025-07-11*

Doesn’t have any free or trial access. Can’t do anything without paying for a subscription and that wasn’t stated up front. If you read the description it was not even checked for grammar. Only a professional cell surfer would pay for a tower map.

**Developer response:** Thank you for taking the time to share your feedback. I sincerely apologize that our app's pricing structure and free access options weren't clearly communicated upfront - this is definitely something we need to improve.

Regarding the value proposition, while I understand tower mapping may seem specialized, many users find it helpful for network troubleshooting, coverage planning, and understanding service quality in their area.

If you'd like to give the app another try, I'd be happy to help you understand what features might be most useful for your specific needs. Your honest feedback helps us build a better experience for everyone.

### 4/5 — Fun and helpful app

*2025-06-10*

It’s a very fun and helpful and the UI is great! I give this app a 4.5 out of 5

**Developer response:** Thank you so much for this wonderful review! We're thrilled to hear that you find the app both fun and helpful, and that you're enjoying the user interface. Your feedback about the UI is particularly meaningful to our design team - we put a lot of effort into creating an intuitive and visually appealing experience.

We'd love to know what would make this a perfect 5-star experience for you. Feel free to share any suggestions or ideas you might have. We're always looking for ways to improve and your input is invaluable in helping us make the app even better.

Thanks again for taking the time to share your positive experience!

### 1/5 — Ne pas installer

*2025-05-16, version 1.3.10*

Une fois l’appli installée vous ne pouvez la désinstaller.

### 1/5 — Confusing APP

*2025-04-28*

This app is supposed to show cell phone towers but you can’t tell what kind of towers you are looking at. It shows location but not strength of signal. Very confusing to even try to use this app.

**Developer response:** Thank you for your feedback! I understand your frustration with the app's clarity around tower types and signal strength information. You're absolutely right that this information would be valuable for users trying to understand their cellular coverage.

We're actively working on enhancing the app's functionality, and your suggestions about tower identification and signal strength indicators are noted for future updates. In the meantime, you can tap on individual tower markers to get more detailed information about each location.

If you'd like to share more specific details about what tower information would be most helpful for your use case, please feel free to reach out. Your input helps us build a better experience for everyone.

### 1/5 — Doesn’t work

*2025-04-23*

Shows no tower which is not true

**Developer response:** Thank you for your feedback! I understand your concern about the tower display issue. This sounds like it could be related to a location services or map rendering problem that we'd like to help resolve.
To better assist you, could you please try these troubleshooting steps:

Ensure location services are enabled for the app in your device settings
Try refreshing the map or restarting the app
Check if you're in an area with good internet connectivity

If the towers are still not appearing correctly after trying these steps, this may be a technical issue we need to investigate further. Your experience helps us identify and fix these problems to improve the app for everyone.
Would you be able to share more details about your location or device model? This information would help us better understand and resolve the issue you're experiencing.
