Opensignal Internet Speed Test 4+

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.

New version removed the most useful function!

[Updated, 8 June 2020]: Changed my rating to 3 stars now that the signal compass feature has been restored (as of app version 5.2.2). Would give it another star except that the upload part of the speed test feature consistently fails for me (starts, but fails with message “Error”). Of 24 speed tests, only 3 completed that part of the test.

Just updated the app (to version 5.0.3) only to discover that the most useful function has been removed: the cell tower signal direction indicator!!!

That feature has been used by many people over the years, like me, to determine in which direction to point the antenna of my cell signal booster in order to obtain the best connection.

It totally makes no sense at all why the developers would choose to remove that function, and also to not announce it in the version release notes.

Two thumbs down! This app is now mostly useless. The speedtest function hasn’t worked reliably or at all most of the time for over a year. And the cell signal mapping is mostly useless because of low participation outside of large metropolitan areas, and if you’re in such an area you’re likely to get a good signal anyway.

Developer Response ,

Thank you for your feedback. We had to take out the signal compass for a little while to fix a number of bugs but I'm glad to report that we have now added it back; all fixed, re-designed and ready for you to use. We hope you'll like the latest version of the app and find it more useful!

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.
