Hello 2804christy,
If the GPS location is not accurate on your device, first make sure that the main location services option is enabled, as well as that it is turned on for the specific applications you're trying to use it with.
1. Go to Settings > Privacy & Security > Location Services.
2. Make sure that Location Services is on.
3. Scroll down to find the app.
Turn Location Services and GPS on or off on your iPhone, iPad, or iPod touch
For the best location accuracy, make sure your device has a clear view of the sky. For example, if you're inside a building, the GPS location may not be completely accurate.
If you have any sort of case or cover on the device, try removing it and see if that makes a difference in the accuracy. If using a case with metallic components, that can affect the GPS and cellular antennas causing an inaccurate location.
If you have the device connected to a Wi-Fi network, try turning Wi-Fi off to see if the location accuracy improves. When using Wi-Fi, the location comes from the IP address from your ISP, so it may not be completely accurate to your true location.
Aside from that, make sure you've covered the basics like restarting the device and making sure it's up to date.
Restart your iPhone
Update your iPhone
If it's still unable to obtain an accurate GPS location, you'll want to contact Apple to report the issue with the device: Get Support
Cheers!
