DRFusionTrack

DRFusionTrack is a Garmin Connect IQ watch app for navigation, motion tracking, dead reckoning, and FIT logging. It combines local motion and heading estimation, GPS quality gating, and a dead-reckoning model to create a practical tracking solution for wrist-worn route and activity recording. This app processes activity data locally on-device. It does not collect or transmit additional personal data to a separate server. Any activity upload or synchronization is handled through Garmin Connect under Garmin’s standard privacy terms. This implementation also includes recent runtime updates for source tracking, signal normalization, motion confidence fallback, and simulator-safe validation paths so that route behavior remains observable and analyzable during testing and recorded activity sessions.
