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.

Helped me solve my iPhone GPS issue

I had to buy an external gps to get things like google maps working on my phone. Apple refused to acknowledge my issue was a bad gps chip. This app worked flawlessly to show the Apple Genius that my issue was indeed hardware and not software. Connected via the phone GPS — no satellites found. Connected via a Garmin external GPS and suddenly fantastic satellite strength. Absolutely fantastic customer support from the development team as well who helped me with the diagnostic.
