1. 5/5Thank 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 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.

2. 5/5Very 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.

3. 5/510 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.

4. 5/5A Masterclass in App Design and Functionality

   The GPS Diagnostic app is nothing short of phenomenal. It’s incredibly refreshing to find an app that not only meets but far exceeds expectations. Where do I even start? First off, the user interface is clean and intuitive. The app is surprisingly easy to use but doesn’t compromise on the depth of its features or settings. Navigating through the options feels like a breeze, thanks to thoughtful design choices. What sets this app apart is the exceptional in-app help and documentation. Far beyond what one would expect, it offers just the right amount of information, in just the right place, at just the right time. The attention to detail in providing this support is truly remarkable and way above the prevailing standard. Overall, GPS Diagnostic is a shining example of what an app should be: functional, user-friendly, and respectful of its users’ intelligence. I couldn’t recommend it more highly.

5. 5/5Garmin GLO - The Missing App (and more)

   I've long been a fan of Garmin devices but was frustrated by the "just trust it's working" nature of the Garmin GLO 2 bluetooth GPS receiver. Garmin offers no status application to confirm device operation and basic navigation parameters. All you get is single LED on the device. This app is FANTASTIC. It works well with the GLO 2 and provides the information that adds confidence to the device. It's also great for built-in GPS, as it provides all critical navigation information. Most of the time, I just want to know the coordinates and altitude. All of this information is front and center in this app. The app makes it simple to copy and paste coordinates. It doesn't require a login or internet connectivity - a great weakness of many "full featured" gps/navigation apps. Simplicity is a huge benefit of this app. This app is worth every penny.
