Buildings and indoor spaces
Tall buildings can reflect or block satellite signals, producing a shifted or zig-zagging route. Indoor spaces often reduce satellite visibility further.
Move to an open outdoor area and allow the device to establish a usable location before starting when practical.
Trees, terrain and tunnels
Dense tree cover, steep terrain and other obstructions can reduce the sky visible to the phone. Tunnels can remove satellite access entirely for part of a route.
A missing or low-quality section can affect distance, pace, route closure and covered-area geometry.
Location permissions
Location Services must be enabled and Marchh needs location permission for its movement features. Precise Location should be enabled where available if the product is expected to record a useful route.
Removing permission can prevent maps, activity recording, covered-area calculation or territory capture from operating correctly.
Background activity and battery behavior
With the necessary permission, Marchh may continue receiving location for an intentionally started activity while backgrounded or while the device is locked.
Operating-system battery or background settings can interrupt that behavior. Check them before a longer activity if recording previously stopped unexpectedly.
What Marchh does with poor data
Marchh may ignore points that do not meet accuracy or integrity requirements and may reject an activity or territory result that appears corrupted, implausible, duplicated or manipulated.
This means a recorded outing and an accepted territory claim are different outcomes. Contact support for repeated technical problems with device model, operating-system version, Marchh version and a non-sensitive description.
Questions people ask
Can Marchh guarantee exact GPS measurements?
No. Marchh's Terms explicitly say route, coordinate, pace, distance, covered area, territory boundary and map position are not guaranteed to be exact.
Does restarting recover missing GPS points?
No. Restarting cannot necessarily restore location information that the device failed to record.
