Crowdsourced results contributed by users of our app have been a valuable part of our mobile performance CoverageMap. Apple’s recent release of iOS 8.3, however, has altered our ability to access and display your test results.

The release of version 2.4.4 of the app fixes the issue preventing Data Speed test results from properly displaying on the map. We’re still working to correct the remaining issues preventing display of Call Performance and Network Technology results on the map.

We appreciate your patience while we get things sorted.

What's New in Version 2.5

Background collection is an exciting new feature available in the app on iOS 8 and higher. It lets you anonymously contribute information about your device’s data performance based on the things you already do on your phone. This is all done in background while not consuming any additional bits from of your mobile data plan. As always, all information collected is entirely anonymous and you can opt out at any time.

Customer Reviews

Background needs more intelligence

Maybe the background activity tracker could be more intelligent and know when I'm traveling, or only collect information while the phone is being charged. Huge battery hog running gps all day.

Happy to contribute, but...

This app is a battery hog if you chose to be a background app contributor.

Final chance - only shows ideal results, no fixes, no settings, ...

The developers just don't get it. Showing only the fastest recorded speed is idiotic, because one single best result throws off the whole representation. Known black spots with zero data in/out when inside a building or outside are now perfectly great, because of a single nearby outside LTE test. Despite hundreds of failed test and test under a fraction of a mb!!! This is just like the overly optimistic nationwide coverage sales map in a single color BS. At a minimum it should by default show the median value, with then perhaps the option to show / toggle to best & worst. A single good result should not invalidate 500 poor ones!!
Still dislike the redesign and unneeded color changes. Three different color legends? And the best color is blue here, green there ... Just stick to the old black, red, yellow, light green, dark green for all. One color scheme done.
Where is the toggle to only test cell network? Can't turn data testing off? No 3g only testing (preventing mass data consumption) Im happy to help map the state (tons of no signal up to two bars of 3g) and poor coverage areas, but absolutely not when it blows through 25MB or more every 30secs when I happen to pass an LTE tower. I want LTE voice signal and 3G data only. Or if it sees LTE that it just waits altogether till LTE is gone. Other ideas and feedback, still not implemented. Sad sad sad. Can't use this any more to put pressure on providers. Can't use it to estimate coverage quality due to favoring one ideal data point out of hundreds. Literally have hundreds of test runs in my area. One great result negates it all.
