Why a trip can miss an unusable GPS gap

The task

Choose the profile before starting and confirm the units. The recorder accepts usable location fixes, filters implausible movement and avoids inventing a distance across an unusable gap. Keep Waymark in the foreground during recording. If you leave the app or stop location access, a complete background travel log should not be expected from this release.

A Waymark trip is a recording session with a start and end, accumulated distance, moving and stopped time, a maximum speed and a vehicle profile. It is not a stored line of route points. Trip distance is the main instrument reading; speed remains available beside it. An unfinished session and a saved trip are different states, so the final save is an important part of the workflow.

Follow the workflow

The app does not invent the distance travelled during an unusable gap.

• Notice the fix interruption
• Keep the app visible when possible
• Review the gap context after saving

Review the result

A session includes a tunnel or another interrupted interval. This is an illustrative scenario, not measured field-test evidence.

Read distance and timing together rather than judging a session from one number. Moving average excludes stopped time by default; the alternative average includes it. A pause you chose, an automatic pause and a GPS interruption have different causes. Note which occurred when comparing two sessions, especially if one journey included long stops or a period away from the app.
