Speed Vario

New in v2: automatic ski run & lift tracking, glider IGC files, and 3D fly-through videos. Real-time speed, altitude & variometer. No ads, no account, fully private.

Speed Vario is a precise, real-time GPS speed and altitude logger for iPhone and Apple Watch — built for cyclists, hikers, paragliders, skydivers, sailors, skiers, glider pilots and light aviation enthusiasts who want accurate motion data without subscriptions or accounts.

LIVE DASHBOARD • Real-time speed in km/h, mph or knots (kt) • Altitude with GPS + barometric complementary filter • Vertical speed (variometer) — climb / descent rate in m/s, ft/min or kt • Live glide ratio in flight • Heading with 8-point compass rose • GPS quality indicator (No Fix / Weak / Fair / Good / Excellent) • Automatic unit switching by activity

SESSION RECORDING • One-tap start / pause / resume / stop • Tracks distance, duration, max speed, average speed (and moving average) • Records D+ elevation gain and D− elevation loss • Keeps running in the background with the screen locked • Crash recovery — interrupted sessions are restored on next launch

SKIING (Sport mode) • Automatically splits your day into descents (runs) and lift rides • Day dashboard: number of runs, lifts, ski distance, D−, top speed • Piste names (with difficulty colour) and lift names from OpenStreetMap, cached offline • Off-piste flagged; speed measured along the slope (3-D)

AVIATION • Barometric + GPS altitude fusion, QNH and pressure altitude (flight level) • Airborne time detected automatically, optional pressurised-cabin mode • Flight detail: route departure → arrival (ICAO codes via OpenStreetMap) and landing count • IGC import / export (gliders) — compatible with XCSoar, SeeYou, WeGlide

APPLE WATCH • Live display (speed, altitude, Vz, distance, D+/D−, heading, heart rate, calories) • Standalone recording: if the iPhone is out of range, the watch records on its own, then syncs • Haptic variometer for paragliding: taps your wrist at a rate that follows the climb • Tuned for long days (skiing): sensors optimised for battery life

HISTORY & ANALYSIS • Full session list with key stats and flags of the countries crossed • Interactive map with speed-coloured route • 3D terrain view with real elevation data — no account or token required • Scrubber to replay any moment; altitude, speed, Vz and heart-rate charts • Track editing: trim start/end and altitude correction, revert to original anytime

APPLE HEALTH & EXPORT • Saves workouts to Apple Health with the GPS route (no duplicate when the watch recorded) • Video export: 3-D fly-through replaying your track over real terrain • Export GPX, CSV, KMZ (Google Earth) and IGC; import GPX, CSV, IGC • Full archive: back up / restore your entire history as a single .zip file

SETTINGS • Metric, Imperial, Aviation or Nautical units • Configurable auto-stop and history retention • Optional Face ID / Touch ID app lock • Languages: English, Français, Español, 中文 (简体), العربية

PRIVACY • No account required — works offline • All data stored locally on your device • No analytics, no ads, no trackers • GPS history excluded from unencrypted iTunes / Finder backups • Automatic deletion of sessions older than your chosen retention period
