Love this app

I wanted to provide some feedback and suggestions:

When using the map feature, could you make my selection permanent? Every time I access the maps section, it prompts me to grant motion and location access. Once I grant this access, it should remain active and not require me to grant access repeatedly. I think a better approach would be to ask for this configuration when someone first uses the feature and then store it.

Love app but needs bug fixes

Love using this app to Speedtest and see how fast carriers are when I travel…but the app glitches often and I have to close the app swipe it out of task manager as new open it to get it to show data when I click on a square. This happens often having to close the app completely out swipe it closed then re open to view sad. Happening on all the iPhones I use for testing so isn’t limited to just one device. If this was fixed would be 5 stars for me

So so

So So

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.

FAQ

What does the Coverage Map app do?

Coverage Map provides a crowdsourced map of cellular network performance and coverage in the US, Canada, UK, and Puerto Rico. It allows users to see real-time speed test data, compare download and upload speeds, and check latency for different carriers in specific locations.

What are the key features of Coverage Map?

Key features include a real-time, crowdsourced speed test map with detailed performance metrics, a built-in speed test to contribute data, signal strength mapping (US only), and data-driven coverage reports (US only) showing carrier rankings and performance percentages.

Is Coverage Map free to use?

The application is free to download and use, but it does display advertisements. There are also in-app purchases available, though the description does not specify what these purchases entail.

What devices is Coverage Map compatible with?

The description does not explicitly state compatibility requirements. However, as a mobile application, it is designed for smartphones and tablets that can download and run applications from their respective app stores.

How can I use Coverage Map to check my cell service?

You can use the app to view the crowdsourced speed test map to see real-world performance reported by other users in your area. The Signal Strength Map (US only) can show you where each carrier has strong or weak reception, helping you understand coverage footprints.
