Pros and cons of GPS Diagnostic: Satellite Test app for iPhone and iPad

GPS Diagnostic: Satellite Test app good for

Helped me prove to the Apple Store "geniuses" that my GPS chip was not working. Got my iPhone 6 replaced as a result which would not have been possible without this cool app. Thanks !

This is a great app for both developers and users. It helped me allocate a GPS problem with my iPhone. A nicer user interface would be even better.

I like this app. It is quick to detect GPS and cellular signal. I can easily forward my location to my friend. It is the best GPS signal diagnostic tool. I would recommend to my friend.

Shows you whats under the hood when using GPS - the actual data coming from the phones receiver, including satellite signal strength, etc. includes other phone sensor data - and ability to reset/restart the GPS. Very handy when any GPS app is giving up.

This is the only GPS utility that you will need to have as it covers all the bases. Concise screen layout provides for easy reading of data. Well worth the purchase price without a doubt.

This app is really great to both verify the functioning of your GPS and it also provides a lot of great information. highly recommended!

Some bad moments

I work for a wireless provider and our equipment requires a GPS antenna that has high visibility to the sky. Ive tried other apps (GPS Status, GPSInfo, etc) to compare results. They will give you the vertical and horizontal accuracy and a "poor fix", "good fix" and "excellent" fix. I recently had a problem with low sky visibility and found that these apps really did not change when I would move my phone around with the apps running. I then tried this app and using the bar graph it did display the slight changes in signal when I moved the phone around. I was able to relocate the GPS antenna and resolve the receivers GPS reception. This app is exactly what I was looking for. Easy to use and read. Great work on this app!

Ive checked this version and it is still working as expected. Ive shared this app with other co-workers and trying to spread the word. This app works as advertised and is the most helpful GPS app in the iTunes Store for my application. Thanks again for the great work!!

I can now clearly see if my location comes from a GPS signal or from another signal source - brilliant. Its the only app Ive seen with a satellite bar chart and it responds to small signal strength changes as I move within and between buildings, allowing me to map GPS black spots. Extremely accurate and simple to use. A very useful app to have in your tool box. Top quality and I highly recommend it.

This is the only GPS utility that you will need to have as it covers all the bases. Concise screen layout provides for easy reading of data. Well worth the purchase price without a doubt.

Excellent app. Really nice format in displaying measurements and great layout making it easy to understand. Works great for my purpose in the field.
