Internet Speed Test Speedcheck

Speedcheck lets you measure download, upload, and ping speeds on both cellular and WiFi networks. With one-tap tests in under 20 seconds, you get fast, reliable results and can contribute them to SpeedSpot's global WiFi speed database. A built-in bandwidth calculator helps estimate transfer times for large files across connections.

The extension also pairs with SpeedSpot's WiFi Finder to locate the fastest hotspots worldwide. You can track your past results, comment on tests privately, and share results on Twitter and Facebook. Privacy policy and Terms of Use are available for review.
