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.

This App still does not accurately display the correct tower that you are connected. Other apps show I am connected to different towers and moving to other towers as the signal changes. Open signal always displays connected to the same incorrect tower with no changes. Many of the towers are not found on open signal maps. open signal tower maps have not been updated in the past year or more. This app should also be updated to display the band that the tower is using like other apps.

The new app has hidden and over simplified the cell phone tower locations map. This was an important feature since phones often use multiple towers at once with Dual-Band Dual-Cell HSDPA. Now it just points to the closest tower. If no one has already tested in that location (often happens in remote areas) this make it more difficult to figure how to get the best signal between towers or for planning a trip in advance with the inability to choose a different location and the lack of information.

Although the app has a considerable array of features, it is still simple and straightforward to use. Furthermore, one of the reasons I'm giving it five stars is that there is no shortage of explanations for the technical terms having to do with telecommunications, wireless signals, data streams etc. I was never bothered by any ads, and the physical functionality of it and the extensive database of coverage maps is not lacking at all, in my opinion.
