Check location access before moving
Confirm that iPhone Location Services are on and that Marchh has the location permission needed for the activity. Enable Precise Location where that control is available. Without suitable access, Marchh may receive no position or only a less useful approximation.
If you changed permission while troubleshooting, return to Marchh and begin a new activity only after the setting is in effect. A permission change cannot reconstruct points that were absent from an earlier recording.
Start where the sky is easier to see
Go outdoors when possible and allow the device a moment to establish usable positioning before starting. Indoor rooms, tunnels, underground areas and streets between dense tall buildings can obstruct or reflect satellite signals.
Heavy tree cover, terrain and weather conditions can also affect the result. If the displayed position is clearly unstable, moving to a more open safe location before recording may give the phone better input.
Carry the same device for the full route
Keep the iPhone with you throughout the Walk or Run. Marchh can only work with samples supplied by the device during the activity, so leaving it behind or moving it between people breaks the relationship between the route and genuine movement.
Do not use fake-location tools, GPS spoofing, replayed data or automation. Manipulated information can produce unusable geometry and may be rejected under Marchh integrity rules.
Allow an active recording to continue
An intentionally started Walk or Run may need location access while Marchh is backgrounded or the iPhone is locked. Required background permission and operating-system battery behavior can therefore matter during that active recording.
Avoid force-closing Marchh in the middle of the route. Review device restrictions if a recording repeatedly develops gaps after the screen locks, then read the background-location guide for the privacy boundary around this behavior.
Review the shape, not an invented accuracy number
After finishing, inspect the recorded activity for large jumps, gaps or a line that misses the route you actually followed. Distance and pace may also vary when accepted points vary, but Marchh does not promise a fixed accuracy radius.
A usable activity still does not guarantee territory. Closure, geometry, location quality, integrity, existing territory and other current rules can affect that separate result.
When the problem continues
Try a simple outdoor route in a more open area after checking permissions. If multiple activities still show unexpected gaps, consult Marchh Support and provide the iPhone model, iOS version, app version and non-sensitive detail that identifies the activity.
Do not repeat a route when conditions are unsafe merely to test GPS. Traffic, access rules and surroundings take priority over producing a tidy line on a screen.
What not to do while troubleshooting
Do not edit or manufacture a route to make it look cleaner, and do not rely on a single on-screen point as proof of exact positioning. Restarting repeatedly inside the same obstructed place is unlikely to change the physical signal conditions.
Avoid disabling safety or security controls merely to pursue a territory result. If a device setting has an unclear effect, use Apple's current guidance or Marchh Support rather than adopting an unverified workaround.
Questions people ask
Can Marchh make phone GPS perfectly accurate?
No. Marchh depends on device and environmental inputs, so even a correctly configured outdoor recording can contain normal variation.
Does a cleaner route guarantee territory?
No. Better location data helps describe the movement, but territory also depends on closure, geometry, integrity, conflicts and other rules.
