D2C Tracker helps you explore Direct-to-Cell satellite coverage from your current location. View compatible satellites on an interactive 3D globe, sky dome, or horizon display. The app uses current orbital data, local terrain, RF geometry, and satellite motion to estimate which satellite is most likely to provide service. Features include: - Live 3D globe and local sky views - Likely serving-satellite estimates - Elevation, azimuth, range, Doppler, path-loss, and uplink estimates - Offline state terrain packs for line-of-sight modeling - Background location tracking and Live Activities - Data-freshness and terrain-coverage indicators - Optional low-traffic Internet link diagnostics - GPS and manual-location support - On-device orbital and terrain calculations D2C Tracker is independent software and is not affiliated with or endorsed by SpaceX, Starlink, any wireless carrier, or CelesTrak. Satellite identity, serving probability, RF performance, and connectivity quality are estimates, not modem-confirmed measurements and should not be used for navigation or safety-critical decisions.
