About

This app provides a crowdsourced map of cellular network performance and coverage across the US, Canada, UK, and Puerto Rico. Users can view real-time speed test data, compare carrier performance, and check signal strength in specific areas. It also includes a built-in speed test to contribute to the map.

Nice app

I love this app it’s great for checking coverage across carriers without having to use the carrier provided ones which suck. I also like you can run speed tests while driving and log datapoints in the crowdsourced map as well.

Keeping carriers honest

Love this app as it lets me see which carriers tend to perform better in a given location. This is great when recommending a carrier to a friend or colleague, and to check what the experience of a signal/carrier is in a given area! Love apps that use crowdsourced data like this!

Garbage

The UI fails constantly and requires forcing the app to close and reopening to fix. They really should use native Apple apis rather than multi platform dev tools. The difference is quite noticeable.

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.

Not accurate

I do not have a strong enough cellular signal outside my home or inside on Verizon cellular. The app shows me solidly inside a Verizon area. It also shows no signal area for T-Mobile. However my neighbor has 5G T-Mobile signal and I can physically see the T-Mobile tower in a hill across from my house. The app is not helpful if it is not able to give correct information.

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.
