Thank God...

Literally one of the most useful apps I have ever used. My iPhone X was having horrible GPS issues under an iOS 11.4 install. I suspected a hardware fault after this app proved the phone was not pulling <any> GPS satellites and was instead relying on cell tower triangulation. After I did all the (failed) usual internet tips of resetting network settings, resetting privacy settings, toggling cell signal, etc. I thought I had proved the hardware fault. Went to Apple store to shove it under their nose. But there was a freak break-in the night before and the store was locked shut. Desperate and dejected, I went back home and decided to do a full wipe and reinstall for giggles, thinking nothing would change. Lo and behold, GPS diagnostic shows multiple satellite tracks after the wipe and reinstall (iOS 11.4). And a full on lock while standing outside using Google maps. Moral of the story: this can’t necessarily PROVE the exact nature of your hardware or software problem, but it can flag for you whether or not your GPS is actively tracking satellites. Knowing is half the battle. From there, it’s up to you to guess and check where your exact problem lies. Still saved my life because there was no other way to get this critical satellite feedback data. Now I don’t have to go to (another) Apple Store tomorrow! 5 stars.

Very useful tool if maps act weird.

Used this app to determine that my internal gps antenna/software weren’t functioning correctly. When any mapping software was open they often didn’t seem to accurately display my exact location and any movement shown I was inaccurately spinning or wrong streets or direction etc etc. This awesome little app was extremely useful as it displayed whether I was actually connected to gps satellites and I discovered that I wasn’t. After firmly pressing on my phone where the internal antenna was located would reconnect a loose antenna and viola, a refresh of the app displayed correctly connection and functioning and my navigation apps instantly worked better then I thought they were supposed to to work to begin with. THIS IS AN AWESOME GPS DIAGNOSTICS TOOL and will be a permanent addition to my utilities folder of apps. I cannot say any bad about it at all.

10 Stars! Apple Diagnostics Useless

This App is Fabulous!
Apple refuses to update their Apple Store / Apple Care troubleshooting diagnostics to include ANY GPS Functionality.
If you have such a problem they will tell you that you have No Problem. They will either deny it (Because it passes their tests ) or suggest you buy a new phone (sighting their diagnostics do not find ANY problem with your GPS).
With this diagnostic, I was able to prove the issue to Apple in seconds, but as my phone was out of warranty it was obvious they weren’t going to do anything about it. Tell anyone you know about this diagnostic especially if their phone is under warranty!
In my case I was able to repair the iPhone 6 hardware issue by reconnecting the “F” antenna of which one side had come loose during the defective battery replacement procedure.
