OpenSignal Speed Tests

OpenSignal speed tests measure your real experience of mobile connectivity and signal. The speed test runs a 10 sec download test, 10 sec upload test and ping test to determine the speed you will likely experience. The speed test runs on common internet CDN servers. The result is calculated with the middle range of samples.

Check if you're getting the network quality you're paying for from your mobile network or internet provider. Use our coverage maps to compare networks and data speed in your area. OpenSignal works with WiFi mobile broadband internet.

Video Speed Tests

Slow video load time? Video buffering? More time waiting than watching? A good average network speed isn’t enough for a great video experience. OpenSignal’s video test gives you the full picture of your network experience. OpenSignal video tests show you exactly what to expect with HD and SD videos.

Watch a 15 sec video snippet to test and log load time, buffering, and playback issues in real-time.
Monitor how video quality changes with time and location. Review video test results in History to see if your network experience has changed over time.

Availability Stats

OpenSignal calculates the time you’ve spent on 3G & 4G/LTE or had no signal. This shows your network availability in the places you use your phone the most.

See where you are getting 3G & 4G/LTE and check you’re getting the service you’re paying for from your network provider. If not, use the data to prove connectivity and signal issues to your mobile operator.

Coverage Map

OpenSignal’s coverage maps show 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 speeds ahead of a trip, find out if you will get a signal in remote areas, check your signal against others in the area to see if you’re getting the best service, arrange the best local SIM and check the signal strength when travelling.

Improving Network Connectivity

We provide an independent source of truth in mobile network experience: A data source that shows how users experience mobile network speeds, gaming, video and voice services worldwide. To do this, we collect data on the signal strength, network, location and other device sensors. You can stop this at any time in the settings. We share this data with network operators globally and others in the industry to drive better connectivity for all.

What’s New

Version 5.2.2

We’re thrilled to let you know that the signal compass is back in OpenSignal!
We had to take out the signal compass for a little while to fix a number of bugs. It is now all fixed, entirely re-designed and ready for you to use! The arrow points you to the direction of the nearest cell tower giving you the direction of the strongest signal.

This release also includes a number of bug fixes and improvements.

Great app but needs some tuning.

Been using this app for over a year now and it seems to really gives you the best average speed test rather than maximum speed. I have Ookla SpeedTest and I use it to compare the differences of its performance and Ookla (and other speed test app) does only give you what your cell signal/Wi-Fi maximum speed is and Open Signal gives you the real speed that you’re always averaging. This app would be perfect if the developer can make it for you to delete your old test records (you can but it comes back after resetting the app) and needs to add location to where you test your signal and Wi-Fi so you can keep track of where you had already test the signal. There seems to be a problem with the find cellular signal. I’m standing right next to my cellular sever (T-Mobile) and it’s pointing away from it?. Other then that this is a great speed test app. 3 stars for now.

Just another speed test app

Although prior revision was lacking, This used to be recommended to help find cell towers for pointing cell booster antennas, but that was not great since basically I found it used old data on cell tower locations and made arrow at one it thought closest. Well we had one even closer that it did not have on its map. We found it just by driving around and looking at number of bars of signal on phone. So app useless.
Description mentions WiFi signal strength but nothing on app says WIFi.
No data on map when zoom in too far.
Now they made it into nearly every other speed test app. I already have 3 others, so useless on that topic as well. Will not be using thus app. When is someone finally going to make an app to tell us where closest and strongest cell tower is from current location and provide a arrow pointing what direction it is, seems so basic an idea. Would help cell signal booster installations.

Good idea; needs improvement

I especially like that Open Signal offers competition to Ookla‘a well-known speed test apps. This app gives good real-world performance insights into each of the networks you might connect to.

The app does not detect when switching Wi-Fi networks and needs to be force quit and relaunched to pick up the change. When switching from one Wi-Fi network to another, running a speed test will tag the result with the previous network name and often fail to compete the test at all.

The data usage feature is interesting but doesn’t seem work either. Usage results are not updated without force quitting and relaunching the app.
