Waypoint Tracker

No GPS. Your phone's motion sensors estimate each step and direction, then the local waypoint map updates as you walk.

The waypoint is stored at your current motion-tracked X/Y position.

Tip: when you physically reach a waypoint, tap its ◎ button. That snaps your estimated position exactly onto that waypoint and removes accumulated drift.
Advanced

Lower sensitivity if steps are being missed. Raise it if shaking the phone counts as walking.

Manual direction controls are a fallback if your browser gives accelerometer data but not orientation data.
