A dot is not an exact measurement
Apple describes horizontal accuracy as a radius of uncertainty around a reported position. That means two nearby dots can be consistent with the same real position. Drawing a line through every dot can turn ordinary measurement variation into a tangled apparent walk.
Inside a flat, the problem can be especially visible. Walls, nearby buildings and limited satellite visibility affect the available observations. Leaving the app open longer does not make every tiny movement on screen become reliable evidence.
Separate movement from a changing estimate
Consider a phone that reports points around one building for an hour, then follows a coherent route down the street. A useful recorder should suppress the stationary cloud while recognizing the actual departure. A single distance threshold cannot handle every accuracy level or sampling interval equally well.
Nowhop’s current recording policy considers uncertainty, timing and coherent observations. It bounds temporary state instead of retaining unlimited jitter simply because storage is available. Existing historical records keep their original interpretation rather than being silently rewritten by a new filter.
Why the main map avoids a permanent raw line
The main Map emphasizes revealed ground rather than drawing every recent point as a prominent stroke. Detailed routes remain available in Hop and Passport. This keeps routine map use calm while preserving a place to inspect the actual recorded day.
Hiding a line alone is not a data-quality fix. Filtering must also avoid awarding new exploration to unreliable positions. Conversely, genuine short movement should not be erased just because a user prefers a clean map.
Check conditions before assuming a lost journey
Review location permission and Precise Location, then compare a familiar outdoor walk with the indoor pattern. Note the approximate time and whether the phone was locked. That evidence helps distinguish stationary drift from missing background updates without uploading a private route.
See Apple’s accuracy definition and its explanation of GPS obstructions. Nowhop’s development tests exercise filtering cases; they are not proof that every home, phone or city has identical field performance.
Questions this guide answers
Did I really travel the zigzag shown while I was at home?
Not necessarily. Repeated uncertain estimates can create apparent movement. A route should be interpreted with its accuracy and continuity, not accepted as proof of every line segment.
Can the app simply snap all points to the nearest road?
That could invent a journey or move an indoor observation onto a street you never used. Nowhop does not replace personal movement history with navigation directions to make it look tidy.
Will improving the filter change my old totals?
The current policy preserves historical interpretation. New recording rules apply to new observations; old coordinates, timestamps and records are not silently rewritten to make a cleaner retrospective map.
Can a stale indoor fix identify the exact room I occupied?
No room-level precision is promised. Freshness and accuracy are eligibility checks; a delayed uncertain position is not reliable evidence of a room, doorway or new outdoor exploration.
