Testing gps on iphone

GPS Status 4+

Description

This is a very basic diagnostic tool to allow you to have a look and see what information the GPS on your iPhone/iPad is reporting.

With our CamerAlert application we received a lot of bad reviews from users who didnt fully understand how GPS works, and that it is almost impossible to get an accurate location when indoors or traveling at 125MPH in a train. The GPS needs time to work out where it is.

This is where GPS Status comes in handy. You do not just get a good/bad GPS Fix indicator, you get a full readout of all the GPS data including speed and co-ordinates. If you have a GPS connection you will also get an approximation of your current address.

Note that I have determined the following GPS Fix settings:
— Excellent Fix = less than 10M accuracy
— Good Fix = between 10 and 50M accuracy
— Poor Fix = between 50 and 500M accuracy
— Bad Fix = more than 50M accuracy
— No Fix = nothing being reported.

Most GPS issues can be resolved by getting a good GPS Fix before you start moving. This can be achieved best by having a clear view of the sky.

Remenber when the GPS fails you drop back to WiFi or Cell positioning which will be wildly inaccurate. This is not a fault of the GPS applications, but the signal that your iPhone is receiving.

Also you need to bear in mind that some applications may work perfectly well with a bad fix if all they need to do is find your general location to determine what is around you.

Limited functionality but easy and fast

Unless there’s some control I can’t find, all it does is pop up a screen with horizontal and vertical accuracy (yay!) and your lat/long/altitude/speed/direction.
It doesn’t tell you how many satellites it sees, or signal strength or what systems, so I don’t know if it’s just GPS or also GLONASS/etc., but what it does do it does quickly and easily.

Developer Response ,

Thanks for the feedback. Unfortunately the system forbids any app to access the data you mentioned. Will add them if future iOS updates made them available.

Very little information

Waze suggested this app to determine GPS signal strength (which I need to place a network extender in my house). It does give the GPS information that your iPhone is seeing, but I have concerns. My concerns / complaints are:

1. No price was listed in the Apple App Store; doesn’t that mean it’s free? I wouldn’t download it if not free. Yet the App Store said “Payment Processed”. There’s a potential dispute.
2. Where’s the settings button? How to change from meters to feet/miles? Don’t app developers for products offered in the US know we can’t/won’t use metric only tools?
3. Where’s the GPS signal strength indicator? That all I wanted this app for!
4. Where’s the battery usage indicator? Waze wears my iPhone battery down so I only use it on long trips. I wanted an app that showed battery usage, so I could determine optimization and modify my usage according.

I hope the app developer reads this and addresses; if an update is offered with signal strength & settings this might be a workable solution that I’d rewrite this review for. Else, I’ll trash it.

Developer Response ,

1. It’s free, App Store still does a zero dollar transaction though.
2. The latest version now supports imperial units
3. iOS system limitation only allow apps to check horizontal/vertical accuracy
4. This again is not available to the app, can only check in system settings -> Battery. There you can check usage information for all apps.

Rated this app before and I’ll rate it again.

Best app out there to test GPS accuracy.
I just tried a different app in the App Store and the stated accuracy was off.
To the person who asked what a flex antenna is that involves taking apart your iPhone and changing the antenna. Not recommended.
I used iFixit as a guide to change the antenna if you want to go that route.
The rest of the reviews complaining about it being metric. Ridiculous. Just ridiculous.
GPS systems work in meters. Your phone converts meters to feet mathematically but the world runs on the metric system.
Just ridiculous to give a lower rating because it gives the measurement in meters.

Great piece of kit!

I love my dragy! The times it records are pretty spot on and I usually have no issue finding satellite connection. The only thing I would change is being able to pause the recorder until you get to where you’re ready to start, that way you don’t have to hit reset and add a new data log which clutters up the interface while you trying to look at your new time. Other than that I have had no issues with it and I would definitely buy it again. No regrets what so ever.

Developer Response ,

Thanks for your feedback and we are glad to hear you enjoy the dragy experience! We wish to minimize manual operation during drive for the safty reason and sorry for the inconvenience. To easily delete your unwanted records, you can set the time filter for each test mode. Choose History in Me tab, tap the Filter in the up right corner, here you can set the time filter. For example you can set 30 seconds for 0-60mph, then all the records will be split into Under 30s and Other in 0-60mph history. You can delete all the records in Other, and change the filter back to your normal settings to filter out the good timings. Please feel free to contact support@godragy.com if you have any questions or suggestions. We appreciate your support!

App needs some work, trying before buying unit

Heard some good things about this unit and app and wanted to see for myself. I got the app 2 minutes before typing this just to see how the interface is and I cannot even get it to open. It keeps telling me I have no internet connection. Obviously some sort of bug/error. If I cannot even open up the app how can I use this product so what’s the use of buying the unit?

Edit: The dev should put some sort of an offline mode because if this thing has issues with internet then it isn’t really usable. Why would it need internet anyways aside from logging into your account. I’m sure you could use all the features without internet connection if such a mode or setting was available.

Edit 2: Just deleted and reinstalled and it loaded but when I got into the main interface the no internet connection error kept popping up.

App Crashes and is Extremely Slow

Although I like the concept of the app, I’ve had problems with the app crashing somewhat regularly and the app performance is pretty terrible. When you try to load your own profile or your performance times, I have no idea what they’re doing but it takes 20-30+ seconds (why can’t you cache some of the data locally — it’s not a ton of data!!). I just tried to check my messages in the app and it repeatedly asks me to log in. The app is borderline unusable — you can log your performance time but accessing it is difficult.

Also, when it records your performance it will give you different slope measurements for the exact same spot. One time it says 0% spot on and the next run from the exact same spot shows invalid bc it’s -1.3% slope. That’s way too much variation.
