CoverageMap App
Take CoverageMap with you wherever you go. Explore coverage maps, run speed tests, map cellular signal as you travel, and compare carriers from your phone.
App Features
Everything you need to understand and compare cellular coverage, right in your pocket.
Two Ways to Contribute
The maps in the app are built from data collected by people using it. There are two ways to add to them, and both are free.
Speed Testing
Download, upload, and latency
Speed tests run on infrastructure we built and manage ourselves, from the testing API to the servers. Every result is added to the Crowdsourced Map, so the performance data everyone sees comes from real devices on real networks.
- Recurring tests for accurate averages
- Choose your preferred server
- Set data limits to protect your plan
Signal Mapping
Measured reception, collected as you go
Signal mapping records the reception your phone actually gets while you go about your day. It can run in the background, maps both SIMs at the same time, credits roaming carriers correctly, and skips locations it has already covered.
- Optional background mapping
- Dual-SIM and roaming aware
- Exclusion zones for private places
