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.

I believe in open signal and have kept it installed for many years allowing for data collection. But I haven't opened it in a long time. Boy did it get clunky. Does not feel nearly as useful as it used to. And I thought I remember it having a signal strength meter for the cell radio but I couldn't find it at all. I'm kind of disappointed in what this app has become overtime. Although it's maps are still quite useful the app itself is not very data-oriented which is the only reason why I use it

One of few cell tower apps that actually works. Unlike others I have tried, the map display actually works, and shows the location of the cell towers in the area where I am. And, on top of it, it has a network speed testing tool which can actually test the speed and video quality of the cellular networks in addition to WiFi networks. The downside is that this application really needs more than an update, it needs a total overhaul, because there's no 2G or 3G anymore, only 4G and 5G now.

The Open Signal Widget disappeared after the last Open Signal software update. I have been using the widget for over 10 years. In my opinion the widget makes the app so much more useful, as I know at a glance what speed I'm connected at, the signal strength, and direction to the tower. Please bring it back. I have changed to a different cellular network info app in the meantime, and have uninstalled Open Signal.
