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.

I have been using this app to find towers while boondocking in the desert, it helps me point my Yagi antenna at the nearest tower. Well the latest update removed that function so this app is now just about useless as i normally only have one tower in range, I just need to know where it is, this app used to do that, no more so will have to find another way. Why you removed the best feature is beyond me.*UPDATE* I have updated my review two 4 stars as the developers have brought back the compass, which was to me the most important feature, redesigned, might want to add a direction marker at the top of the screen as it is not readily apparent which direction is the alignment point.

ETA: Updated May 2021: 1. The maps do not allow you to zoom in close enough to view signal data in your immediate location. 2.You can zoom out and see a vague collection of blocks, some green and some brown, but when you try to zoom in for a closer look, you cannot.3. I then went to the website, and there are no maps whatsoever. They direct you to use their app to view the maps. The maps are extremely poor quality and give very little information.You cannot view in your immediate area, i.e. a few houses surrounding you, what the average speed is, the low speed, the high speed, to give a true network comparison for your immediate area. They have a “compare networks“ feature, but it is extremely broad.The error message I get when attempting to view closer is that there is not enough data. But this app has been out for years. How can it not have enough data by now? I even positioned the map over a busy business area, and when I zoomed in, it still gave me the error that there was not enough data to zoom in further.I was hoping to start contributing once again to this app. But I hardly see the point when I cannot zoom in for the accurate results. ORIGINAL REVIEW:This app no longer contains exact coverage maps and real results from people’s speed tests.All it is now is a collection of cell phone tower locations which may or may not be accurate.You cannot filter the tower results by different carriers. It will only show you your carrier.What happened to this once excellent app?!

App work well and even worth paying a small price as a useful traveler’s app. Helped us pick a different carrier for our new cell phone plan in Nov 2018 (switch to T-Mobile).App lacks an iPad optimized interface. The iPhone interface on an iPad is very lack-luster.App needs to reduce screen clutter on the Map display. The “info” button obscures part of the visual map for no good reason (not like you need to press the info button regularly). Controls on the map display need to be reduced when interacting with the Map like Safari reduces it’s controls when user interacts with web page.Carrier comparison is nice but would benefit from a visual bar comparison vs just a list of numbers for speed. Just like a head to head comparison of sports cars in Car & Driver, need that speed graph to see the relative benefit of one carrier over another.The Map view would be great if it could draw a line from your location to the closest 4 or 5 towers labeling each line with the carrier name. Having to tap the map points to see the carrier name and info is a little annoying.Map could have percent of coverage for each carrier for a given route. Most of us on mobile devices care about where the carrier drops are along a given route. It would be good to know when the signal was last seen, when the test failed to get internet, and when it was then seen again by the same device. That would help identify dead zones in a periodic checking mechanism.I would be happy to have OpenSignal run all manner signal diagnostics when it is in my car and the phone is plugged in but not when the phone is not plugged in. Need an option for that. Good for the dead zone detection on highways mentioned above.
