About Opensignal - 5G, 4G Speed Test

1. 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.

2. If not, use this data and the individual speed tests to highlight connectivity and signal issues to your mobile network operator.

3. Opensignal is a free to use, advert free mobile connectivity and network signal speed test app.

4. 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.

5. The map shows signal strength down to street level using speed test and signal data from local users.

6. 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.

7. 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.

8. To do this, we collect anonymised data on the signal strength, network, location and other device sensors.

9. Opensignal speed tests measure your mobile connectivity and signal strength.

10. LOCATION: Speed tests appear on a map and also let you contribute to network stats and network coverage maps.

11. The internet speed result is calculated with the middle range of samples. Slow video load time? Video buffering?

Opensignal Customer Insights

1. You can also check your ping, down and upload speeds, and even which direction to find the tower you're closest to ASAP, even before activating the Google mapping service to find it (very useful in situations where you need to make an emergency call, and have poor connectivity, wherein you can't upload a Google map anyhow).

2. It is accurate, the app is easy to navigate, it doesn't take a rocket scientist to understand the graphs & data, & I have found no better or more reliable app to help locate your cell towers in your general vicinity.

3. Not sure if it is the new Android version or not but if I close the app, and opening it again sometime later to view my stats, it starts from zero like it hasn't been on.Amazing app, very useful for comparing networks and speeds in different areas.

4. 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.

5. For example, it won't show you cell tower locations for any provider other than your own, so if you wanted to see who operates that tower right by your house, it's impossible to search to find out.

6. 120.degree sectors appear to be separate towers in completely different locations, some of which are out in open water, which is impossible.It's hard to write feedback for this app, since it's best to comment on each of the various tools within it, but overall it's got issues.

7. Accurate speed tests (mobile or Wi-Fi), locate towers, compare your carrier to others in your area, see how your coverage will be when you travel, and more.

8. I have changed to a different cellular network info app in the meantime, and have uninstalled Open Signal.An incredibly useful app.

9. One time, being close to a tower I was curious to see if the app pointed to it and when I opened the app it was pointing in a completely different direction.

10. I'm not sure what it is depicting, but it's not cell towers, and it doesn't even correctly show my local towers, amidst all the random points appearing on the map.

11. At one time the map was getting updated very roughly every 6 weeks, but it has been almost a year now, the old data has aged out, but none of the new data I have collected has been added.
