Read the display
The lines answer separate questions.
The imported or selected route remains the reference line for the outing.
Successive position estimates form a trail behind the current location.
A direct bearing or line may point towards a useful part of the planned route without selecting a safe path across the ground.
Keeping those meanings separate matters most at junctions, on folded terrain and in poor visibility. The planned route can continue in one direction while the breadcrumbs show the branch just taken. A direct rejoin line may cross a wall, river, crag or private ground because it expresses direction rather than a surveyed route.
The recorded trail
Breadcrumbs are position estimates joined in time order.
A phone or watch estimates its location at intervals. The app keeps enough of those positions to draw the path already travelled. The result resembles a continuous line, although it is assembled from separate samples.
- Good receptionThe trail normally follows movement closely enough to show the approach to a junction or the side of a valley used.
- Poor receptionWoodland, steep-sided ground, buildings or a restricted view of the sky can make positions wander or leave gaps.
- Stopped recordingA flat battery, disabled location access or ended session can leave no usable record for the missing period.
- Stationary driftSeveral estimates can move slightly even when the person has not, so a small knot of points does not necessarily represent walking.
A deliberate recovery
Use recent breadcrumbs to confirm, then judge the return.
- Stop
Pause somewhere safe.
Do not keep moving while trying to interpret several lines on a small display.
- Confirm
Compare the planned route, current position and recent trail.
Look for the last point where the breadcrumbs and route were still together.
- Assess
Check whether retracing remains sensible.
Consider steep ground, water, traffic, daylight, weather and any hazard that has changed since you passed.
- Return
Work back to a confirmed place.
Retrace only when the ground is safe, checking the map and visible features rather than following the screen without question.
Keep the wider picture
The trail does not assess terrain, access or present conditions.
Breadcrumbs do not show whether a river has risen, a path has closed, snow has covered a slope or an earlier descent is now unsafe to climb. Apple makes the same distinction in its Backtrack guidance: the recorded path can support retracing, but the feature does not account for elevation changes or objects in the environment.
Use breadcrumbs to understand where you have been. Use the map, the ground and current conditions to decide what to do next.
