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 is cool! It allows you to see every single tower your phone could connect to.(keep in mind you could only see your provider towers) it also came with a handy speed tester! I'm not too sure about the follow the arrow thing... It doesn't work for me but I'm sure It would work for others! Overall great way to see my cell phone tower!

I've been looking at a number of cell tower locators and this app blows the others away. It seems to show me all the cell towers even the ones I'm not connected to plus it shows me both T-Mobile and Sprint but not at the same time which is puzzling nevertheless show me the location of the towers and having an arrow that points in the right direction is far superior to any of the other apps for cell tower location

Used this app to hopefully point my cell phone signal booster in the right direction. It shows on direction with an arrow saying point the antenna that direction for 100% but the signal on the booster is still non existent. It also shows a small blue line on a different screen that is roughly 120 degrees off from the first arrow with no explanation for the difference. This app simply sucks.
