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.
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.

Ratings and Reviews
On its way to success..
The application is different than the rest, with the idea of a compass directing you to the nearest tower. And the ability to check the speed of you Wi-Fi’s, download, upload, and latency.
The people that write a negative review forget a couple of things.. First, the application is Free! There is so much a free application can do without it being a “ Professional Technician “ and charge you.
Second, even though some of things on the app have bugs, I believe that’s the reason why updates were created.
Third and last, the developer of the application is actually responding your entitled reviews and fixing the issue that you complain about because you can’t afford a professional to fix your internet. Lol!
The #1 tool for the Security & Fire alarm industry
OpenSignal is the best, most important cellular testing tool I have as a professional in the Security & Fire Alarm industry. This free, amazingly easy to use, comprehensive testing & tower locator tool insures that the cellular communicators that we install are using the best carrier available based on signal strength, data latency upload/download speed testing that I perform myself at every location I go to. For me and those in my industry, OpenSignal insures top performance when seconds means the difference in life or death. Having a tool in your hand that tests cellular performance from the exact location you are at, is a dream come true for those who’s job is to secure property, protect jobs, and save lives.
No matter where you are, you know whether you can use the cellular communicators internal antenna or if you will need an outdoor antenna because of the distance you are from a tower or the buildings size or the structures building material blocks the cellular signal. In those areas that a long-range directional antenna is required, OpenSignal shows me exactly where to point my antenna. As a 33 year veteran of the Security & Fire Alarm Industry. I recommend everyone that uses cellular communications to get this app, it’s a Life Saver figuratively and Literally.
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.
