Useless app developed by a reddit mod who recommend this. Scan sengkang/punggol show me list of malaysia telco instead.

The speed is realistic and matches my feel, love the localised ranking and coverage visualisation. Great tool to help identify the network offers the best services.

When you first open the app, it takes a long time for the compass to finish loading and it's just stuck frozen for a few minutes; you can't tap anything. Would appreciate some sort of loading bar/indicator to show that it's still processing.

How I wish there is a time machine software like Mac for iPhone. The previous user interface was so much easier to use and professional looking. After this update it looks like it was designed by someone who went through a 1hour design crash course.

Carrier and Tower Direction not working at all on iPad 3 with ios 7.0.4

Nice smooth running app. Gives a fast and easy test showing latency as well The video test has the super bright colors

Privacy agreement says signal strength is being shared. I was counting on being able to see it. A good place to put it would be by the big arrow when finding the nearest cell tower. This feature didn’t work—no cell tower detected. I like the concept of crowdsourcing this information. The app is on the right track.

This app used to work. Now it says no signal no matter where I am. No white arrow at all even after 3 updates.

How Opensignal is considered the the gold standard, I have no clue! This is one of the least functional apps. From the user interface being abysmal, to the app being not being able to perform speed tests at the maximum download and upload speed that the network is capable of and showing data relevant to the speed test, to the find my tower feature never working, I honestly think they should remove the app and rebuild it from the ground up!

I got this app to help aim my cell phone booster antenna. The signal is weak here and the app had me aiming about 70 degrees off, just barely in the edge of reception. Lately I have been trying to use it to monitor bandwidth with my new WiFi system and about half the time it says it cannot find the server. In summary, better than nothing, not very accurate or reliable.
