WaymarkDefine the outcome
Check the GPS label before interpreting the number. Good, poor, acquiring, lost and denied states describe different conditions. A large numeral is still an approximate phone reading, not a calibration certificate. Configure units and alerts while stationary. Sound or vibration requires the relevant setting and supported device behaviour; neither should become the only cue you depend on.
The main instrument reads live speed from the location service rather than waiting for a trip to start. That makes it possible to inspect a current reading without recording a session. Waymark also shows the state of the location fix, and it distinguishes a missing or stale reading from a live one. The displayed speed and the saved trip maximum answer different questions.
Three checks to complete
A single difference does not establish which instrument is correct.
- Match units
- Record the GPS state
- Compare while keeping attention on safe travel
Final review
A passenger notes readings from two devices for personal reference. This is an illustrative scenario, not measured field-test evidence.
For an instrument check, use a familiar location and observe the interface while stopped or ask a passenger to note the behaviour. Write down the device, profile, selected units and GPS state. Avoid changing several settings during one comparison. A repeatable observation is more useful than a single striking screenshot with no indication of how it was produced.
Quick reference
| Item | Meaning | Keep in mind |
|---|---|---|
| Acquiring | Waiting for usable location | Do not read an unavailable placeholder as zero |
| Poor | Limited location quality | Read the caution alongside the number |
| Lost | The fix is no longer current | A last-known value is not a prediction |
| Denied or off | Permission or location-service issue | Use the recovery action for the stated condition |
