Altitude: Skydive Logbook

Your whole jump day, logged by itself.

Press Start once when you get to the dropzone. Altitude watches the barometer and GPS, detects every jump — climb, exit, deployment, landing — and logs each one automatically with its full flight path. Ten loads, zero taps.

EVERY JUMP, FULLY MEASURED • Exit and pull altitudes from the barometer • Freefall time, average and peak descent, ground speed • Opening analysis: snivel time and altitude used • Canopy: ride time, sink rate, final-turn altitude and direction • Winds aloft, measured from your own canopy drift

SEE IT • Flight path on the satellite map, colored by phase • 3D flight path you can orbit • Animated replay with a scrubber • Wingsuit panel: glide-ratio curve and speed polar

A REAL LOGBOOK • Dense, scannable list — your whole history at a glance • Signatures: hand your phone over, batch-sign with a finger • USPA license progress with per-requirement drill-down • Tag jumps for accuracy, night, and water requirements • Import from Skydive Logger and altimeter CSV exports • One-file full backup, CSV export, iCloud sync

JUMP-DAY WEATHER • 7-day outlook with a jumpability call per day • Cloud layers with estimated base altitude • Winds-aloft forecast for your DZ

AND THE FUN PART • Personal records that celebrate themselves on landing • Badges, streaks, a level ladder from Ground Level to HALO • The Altitude Bank: how many Everests you've fallen • A shareable year-end Wrapped card
