Movement Logger

Movement Logger is the Android companion for the PumpTsueri SensorTile.box,
a wearable that records IMU, GPS, and barometric data while you ride.

Two screens, one workflow:

Sync — discovers the box over Bluetooth Low Energy, lists every recording
on its SD card, downloads them to your phone, and starts new logging
sessions with a configurable duration. The sync keeps running in the
background, so you can switch apps without interrupting a long download.

Replay — pick a downloaded sensor CSV pair and a video of the same ride,
and the app plays them back time-synced. Four data panels stack below the
video:

• Speed ​​(km/h) — GPS-derived, smoothed and outlier-clipped
• Pitch / Nose Angle (°) — Madgwick 6DOF AHRS with drift correction
• Height above water (m) — barometric height with GPS-anchored
reference, complementary-fused with body-frame acceleration
• GPS track — lat/lon path with longitude aspect correction

Each panel shows a moving cursor that follows the video playhead. export
the whole composition as a single MP4 — rider on top, panels below —
straight to the phone's Photos library.

Open source. Built for foilboarders, paragliders, and anyone else who
wants to see exactly what their body and the world did during a session.
