Altimeter Dashboard vs RV

Altimeter Dashboard is a clean, automotive-style altitude and compass dashboard for iPhone. Features: • Large, easy-to-read compass display • GPS and barometric altitude measurement • Real-time heading and directional display • Vehicle display support on compatible in-car systems • English and Japanese localization • Metric and imperial units (metres and feet) • Altitude and heading accuracy information • Altitude trend indication (rising, stable, or falling) Privacy first: • No user accounts • No advertising • No analytics • No tracking • No subscriptions • No in-app purchases All location, compass, motion, and barometric data are processed on your device. Use only when safe and legal to do so.

RV‑Pilot turns your iPhone and CarPlay into a professional‑grade aviation‑style instrument panel. Get precise altitude, atmospheric pressure, climb rate, ground speed, magnetic heading, pitch, and roll — all with full voice alerts that speak directly through your car speakers. Perfect for • Pilots and aviation enthusiasts (VFR support) • Hikers, mountain bikers, and off‑road drivers • Anyone who needs reliable real‑time elevation and attitude data - GPS Altitude Absolute altitude above sea level using CoreLocation (WGS84 ellipsoid, accurate where GPS signal is available). - Barometric Altitude Estimated altitude from the built‑in barometer using the ISA formula (1013.25 hPa reference). Also shows raw station pressure in hPa or inHg. - Vertical & Ground Speed Vertical speed derived from GPS altitude with smoothing. Ground speed in km/h, mph, or knots. - Magnetic Heading Accurate heading 0–360° using the same Apple Compass engine — independent of device orientation. - Pitch & Roll Device attitude in degrees, displayed both numerically and with a bubble level. Updates at 15 Hz. - Voice Alerts Customizable spoken warnings when altitude or speed exceed your thresholds. Use {value} placeholder to hear the actual measurement. Choose any system voice (neural voices supported). Alerts play over car speakers via CarPlay. - Apple CarPlay Integration • 3‑tab interface – Navigation, Altitude, Level • Dashboard widgets (where supported) – colour‑coded live values • Fully independent UI optimised for car displays - Units Switch between Metric (m, km/h, hPa), Imperial (ft, mph, inHg), and Nautical (ft, kn, hPa). - Privacy‑First All sensor data stays on your device. No analytics, no tracking, no internet connection required. Location is used only for GPS altitude, speed, and heading. Reset Δ Altitude Zero the relative barometric altitude counter with one tap — ideal for tracking height gain from a reference point. RV‑Pilot is the simple, reliable, and privacy‑respecting instrument panel you can trust on the road, on the trail, or in the air.
