GPS Diagnostic: Satellite Test App Anmeldelser

It works perfectly.

Easy to use and not more complex than necessary. Great for sending my location.

Now I know why navigation says to turn in 50 feet after I was supposed to have turned!

Works great now.

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.

I successfully used this app to confirm the quality of the reception of satellite data. Months later I find myself in Japan on the Shinkansen “bullet” train wondering how fast we are traveling. This app provided the answer. In case you are wondering, we were traveling about ~275 km/hr!

Very useful app. I really like that it shows your Lat & Lon!! I’m not sure why but it was the only GPS app that worked on the plane! It was nice to see the ground speed and altitude Update - for some reason it no longer works?? I know my GPS is still working because all my apps that rely on it still work perfectly but according to this app it’s not receiving a signal from any satellites! It worked good for years and it just quit . Doesn’t display anything. Tried all the usual things . Restarted my phone checked for updates nothing helped.

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.

Works great but I’d love to see the signal strength of all satellites being received. Not just the first 3.

With the recent ending of CDMA as a time source for NTP servers we had to purchase new units that sourced time via GPS. Running into signal issues this app helped me locate a area where GPS signal was attainable. It’s a simple app but did everything I needed perfectly.

Tried to use it to test my gaps module but it won’t synch…it only appears to be testing my iPad. Not what I needed, not sure what the value of this is….but worth 2.99.

Inside my house 15 feet away from the window this shows I pick up 4 + Satellites. It’s nice to know whatever map app I use I can tell I’m getting a correct reading (location). I recommend this app.

This is a great tool for ensuring my other GPS-based apps are giving me valid information. It is worth the price many, many times over! Thanks so much for your perseverance in creating this! I wish I had had this app back in my earlier days when I was flying Rescue missions and working as a flight test engineer. Invaluable!! Thanks again!!

Excellent app, love it, and recommend it!

Super cool app. Figured out why navigation wasn’t working well — GPS was broken on my phone!

Other apps display satellites - this brings up none.

Have had issues with maps lately on my iPhone 8; very glitchy and seems off to precise location. Downloading this app seems to have helped a lot in resolving the issue.

Ehh aren’t there more apps like this? Without this app, my 2021 iPhone will not show me as much basic GPS info as my Garmin handheld unit, circa 2000. Get this to unlock the power of your phone’s incredible GPS!

My only complaint about an otherwise useful utility.

... what is meant to do! Used this app for school (GIS) -love it!

Muy feliz con esto

I complained in an earlier review that the app was super-bloated @ 182 MB. The developer responded by dropping a version - less than a week later! - that reduced that size by 80%. That's pretty darn responsive. :) Thanks for caring about those of us still stuck with 16gb iphones.

This is the only app I know of that shows the status of the GPS constellation it sees. It does a great job and certainly makes it interesting when the constellation drops out and Apple Maps starts to wonder. It is a must have!

An invaluable app to test your GPS hardware and diagnose problems.

Was looking for an app that would help determine GPS Satélites, WiFi Location, Bluetooth and cell triangulation. This app checks most of my boxes and it’s great when performing location testing with different hardware. It helps diagnose issues with connected devices that rely on gps as wel as FEM2Cell position for businesses that rely on good communication.

Needs a very good signal to show sats. Gives signal strength but not # of sats locked. Not as useful as hoped.

Wanted to see position, hardware usage and status. Works very well. Thanks

This is perfect! I have questions about how to get the best accuracy and what ‘the best accuracy’ means in terms of limits to the technology to the public. Would appreciate a few paragraphs about this to make it clearer. Thanks for a great product!

I tried it and no success,

I used it to diagnose failed GPS on my iPhone 6. Now it is on my 11 and it continues to work well.

Love it use it all the time. Let’s me know if I can trust my gps reading at the moment, also use it to measure my air speed while flying.

This app can’t fix anything. It only shows you the accuracy of the GPS receiver. So what’s the app good for?

This app is a gem. Lately I have been burned on a number of apps here and of course Apple, one of the richest companies in the world, makes it nearly impossible to get a refund. This app delivers and is worth the money.

David has this app working fully on the iPhone 11 now. Now if the other GPS intense apps (Apple Maps, Waze, ...) developers could catch up that’d be swell for all of us!

I hate pop ups

Get app to use when replacing the gps Bluetooth component in my iPhone

I wish the developer had made it clear in the app description that while multiple navigation systems are supported (GPS, GLONASS, Galileo, and QZSS) by iPhone the app can't display which satellite is which due to Apple’s limitations. Consider this also a request to Apple to open this data up to developers, people are interested.

I bought this out of curiosity and I’m very happy with it. Gives you a ton of information about what your phone is actually doing. Great support when I tried using my new iPhone X to map my progress on a commercial flight (no, apparently new iPhones won’t do it any more)

There are several apps that claim to provide GPS diagnostic capabilities. I think I looked at all of the others and they all fell far short of what they claimed. This app performs perfectly!

Could you please add at least 8 satellites bars instead of just 4 bars? Thank you.

My iPhone 6 started having gps problems resulting in navigation apps giving approximate location. Most of the time it shows me off the road. Annoying to say the least. This app showed my GPS had a signal problem. “ GPS on “ “ no signal “. Was able to install a new gps/WiFi antenna. Long story short, my iPhone gps works again. Thanks to this app I got it sorted right away.

The iOS API doesn’t provide signal strength details per each satellite. So the graphical display of satellites 1, 2, 3, and >4 can’t be displaying actual signal strength as you’d find on a real GPS device.

My go-to app for just about anything dealing with iPhone navigation.

Simple, uncluttered design. Functional. Accurate (as checked against Trimble survey grade unit).

This is a great diagnostic tool. I gave it five stars. There is one feature I’d love to see extended: the sat data has four signal vertical bars: 1, 2, 3, 4 and greater. It would be even better if it could horizontally compress and expand to a per-PRN graph with Az-El-S/N data. Great app! 😊

Found this app to work flawlessly. Always accurate information.

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.

I needed an app that would quickly give me my lat/long in whatever format I needed. DMS, DM, or D. This app does it. Perfect for my needs.

waited for the update for too long still no space on MGRS for easy reading
