Hey friend,

If you’ve been following me for a while, you may know that I co-founded CoverageMap.com with my business partner, Trevor, back in 2022.

Our goal?

Make it easy for people to compare accurate, real-world cellular coverage data.

This project has been a journey:

  • March 18th, 2023: we launched a crowdsourced map of cellular coverage in the US

  • May 8th, 2023: we launched the Coverage Search tool

  • June 23rd, 2023: we launched the Coverage Map app for iPhone

  • September 1st, 2023: we launched the Coverage Report Map

  • October 9th, 2023: we launched the Coverage Map app for Android

  • March 11th, 2023: we launched the built-in speed test feature for iPhone

  • January 1st, 2024: we launched the built-in speed test feature for Android

Today, over 100,000 people have downloaded the free Coverage Map app and contributed over 10 million tests. 🎉

This has been absolutely amazing.

And, it gets better.

I am excited to share that CoverageMap.com is expanding to Canada and the UK!

Starting today, Canadians and Brits have access to crowdsourced cellular coverage maps with powerful features and incredible functionality.

This will empower everyone in Canada and the UK to make more informed decisions about which carrier is right for them.

How Can I Contribute?

Wondering how you can contribute to the crowdsourced maps?

Simply download the free Coverage Map app for iPhone or Android, turn off Wi-Fi, and run a cellular test!

Even if your country hasn't launched yet, all of your tests will be saved and will show up when we do launch there.

You can also upload any existing tests you may have taken on other popular speed testing apps, such as Ookla Speedtest, nPerf, or SpeedSmart.

Here’s a video on how to do that:
