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

I've used this app for at least a year. I'm a huge fan of crowd sourced metrics. So being able to see carrier stats based on location is awesome. There is a feature I don't really understand, and that's the compass tower finder. It's never pointed in the direction of a nearby tower. One time, being close to a tower I was curious to see if the app pointed to it and when I opened the app it was pointing in a completely different direction. I could see the appeal, but I haven't seen it work. Last thing is recently my pixel XL has stopped reporting stats. Not sure if it is the new Android version or not but if I close the app, and opening it again sometime later to view my stats, it starts from zero like it hasn't been on.

Amazing app, very useful for comparing networks and speeds in different areas. I've used it for years. However, lately the speed test seems inaccurate. It always used to provide results reasonably close to those of all other testing apps/websites. Lately, it has been reporting speeds that are more than twice as fast as other sources. Realistically, it could theoretically be T-Mobile recognizing the speed test traffic and manipulating results to provide a better network rating on the app. It would be interesting to know if other users from the same, and other, networks are experiencing this is well. It would be quite the scandal if this were occurring.

Sporadic updates keep me from rating this app higher. My data doesn't seem to be getting used. At one time the map was getting updated very roughly every 6 weeks, but it has been almost a year now, the old data has aged out, but none of the new data I have collected has been added. Also, the algorithm for locating a tower is pretty inaccurate. 120.degree sectors appear to be separate towers in completely different locations, some of which are out in open water, which is impossible.
