iPhone GPS Speedometer Not Working? Fix It
If a GPS speedometer is not working on your iPhone, check Location Services, Safari website permission, Precise Location, screen state, and signal conditions in this order.
1. Turn on iPhone Location Services
Open Settings, choose Privacy & Security, then Location Services, and make sure Location Services is on. The browser cannot provide a GPS reading when device location is disabled.
2. Allow location for Safari and this website
In Settings, open Apps, Safari, Location and choose Ask or Allow While Using App. In Safari, open the page settings for zigmaty and set Location to Allow, then reload and press Start.
3. Enable Precise Location
Turn on Precise Location for Safari. Approximate location can be too coarse for a useful live speed reading, especially at low speed or over short distances.
4. Keep Safari active and improve the signal
Keep the page visible and the iPhone unlocked during a test. Move outdoors or near a clear window, leave Low Power Mode off temporarily, and wait for the GPS accuracy indicator to settle.
5. Reset Safari permission and test safely
If it still fails, change the website location permission, reload the page, and restart the trip. Test as a passenger or while walking; never handle the phone while driving or use zigmaty for legal, safety, navigation, or emergency decisions.

Common questions
Short answers for this guide.
Why does Safari say location permission was denied?
Location may be blocked for Safari, for the website, or in iPhone Location Services. Allow it at each level, reload, and press Start again.
Why does the iPhone speedometer stay at zero?
The phone may still be finding a reliable GPS position, Precise Location may be off, or walls, roofs, tunnels, and coated glass may be blocking satellite signals.
Why does GPS stop when I lock my iPhone?
iOS can pause or limit browser activity when Safari is not visible or the screen is locked. Keep the page active during a measurement.
Does Low Power Mode affect browser GPS?
It can reduce background activity and update behavior. Temporarily turn it off while testing and keep Safari in the foreground.
Can zigmaty change iPhone GPS settings?
No. zigmaty reads location data supplied by Safari; permissions and GPS hardware remain controlled by iOS and the device.
