Opensignal - 5G, 4G Speed Test

Opensignal.com

About this app

Opensignal is a free to use, advert free mobile connectivity and network signal speed test app.

Speed test for mobile and Wifi internet
Opensignal speed tests measure your mobile connectivity and signal strength. Opensignal runs a 5 second download test, 5 second upload test and a ping test to provide a consistently accurate measurement of the internet speed you will likely experience. The speed test runs on common internet CDN servers. The internet speed result is calculated with the middle range of samples.

Video playback test
Slow video load time? Video buffering? More time waiting than watching? Opensignal’s video test plays a 15 sec video snippet to test and log load time, buffering, and playback speed issues in real-time to show you exactly what to expect with HD and SD videos on your network.

Connectivity and speed test coverage map
Always know where to find the best coverage and fastest speeds with Opensignal’s network coverage map. The map shows signal strength down to street level using speed test and signal data from local users. With network stats on local network operators, you can check coverage ahead of a trip, check the internet and download strength in remote areas, compare your network to other providers in the area, arrange the best local SIM.

Cell tower compass
The cell tower compass allows you to see which direction the closest or strongest signal is coming from, enabling you to more accurately use broadband and signal boosting technology.
Note: The cell tower compass uses aggregate data and accuracy issues can occur in certain areas. We’re striving to improve this feature and thank you for your patience.

Connection availability stats
Opensignal records the time you’ve spent on 3G, 4G, 5G, WiFi or had no signal at all. This allows you to see where you are getting the service you’re paying for from your network provider. If not, use this data and the individual speed tests to highlight connectivity and signal issues to your mobile network operator.

Ratings and reviews

Still no fix for my Google Pixel 8 Pro running the latest Android 15. The app use to work great but the app will not show any upload speed as it is ALWAYS 0. It's been over a Week and still nothing. I even tried to uninstall and reinstall and still will not show any upload speeds. I've been a long time power user of this app but I think I may need to look elsewhere. 1 Star until fixed.

Use this reg & its usually good most times. The info can prove really helpful & useful when trying to defend urself against mobile carrier claims of service etc in ppls local area but some of the data recently don't seem accurate at all anymore not sure what happened. The tower data looks same etc but for ex the arrow pointing in direction of ur connected cell tower doesn't make any sense cuz it points in the opposite direction now. And moves constantly?! Would VPN cause this inaccurate readin?

Mediocre. Not nearly as good as Sensorly was before it shut down. Ads have been removed and the app has been greatly improved, thanks! There is no measurement mode. I want to expand signal maps at the time of my choice and have zero battery usage and privacy impact otherwise. Useful, but I'm looking for something better.
