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.

Why is my phone reporting WiFi results instead of cellular?

I did a speed test with my wireless router disabled to ensure it would only test my cellular data. All went well, as expected (except I had a terrible test score, not the fault of the app but for T-Mobile—we don’t have 4LTE here even though my connection states LTE.)

My issue with the app is that I then turned on wireless router along with the cell signal and expected this app to know that it should test my cell signal, since I want to hold T-Mobile accountable for the bad coverage in my supposed “4LTE” area.

Instead, the app runs a test on my wireless router connection which of course is blazing fast. Much, much faster than my T-Mobile connection. But I am concerned that it will be reported as a T-Mobile cell result and artificially inflate their numbers.

Also, even though I live in a populated urban area that was one of the first cities to get LTE, the map won’t populate on my area when I zoom in. It states it doesn’t have enough data for that level of zoom. But Open Signal has been around for years and if I go to their website, I can zoom in further. Why is this?

Bad tower data, MIA developer

Great idea if it worked. Towers (for Verizon) not where they claim. I’ve seen them marked in the Potomac and in a parking lot where they don’t exist.

The problem of showing wrong carrier seems resolved, but it went on for years. Attempts to contact the developer about incorrect towers in my area get an automatic response and nothing else. I’m not sure where they get their data but there certainly not cell towers in the middle of the river!
