Good to know
Things worth knowing.
01 How quickly does the live reading update? ⌄
The browser requests a new GPS position fix every second. The speed display updates as each reading arrives — typically within 1–2 seconds of a speed change.
02 Why does it say Waiting for GPS for a few seconds? ⌄
After you grant permission, the GPS chip needs a moment to acquire satellite signals. This is normal and usually takes under 10 seconds outdoors.
03 Does it work indoors? ⌄
GPS is unreliable indoors. You may see Acquiring in the status indicator or inaccurate readings. For best results, use Zpeed outdoors or near a window with clear sky above.
