Cloudbase Altimeter
Your Apple Watch becomes a skydiving computer.
Auto-detects every phase of your jump. Reads altitude in freefall, guides you home under canopy, and syncs everything to your logbook — automatically.
Join the waiting list. We'll let you know when it's ready.
Everything you need in the air
Built specifically for skydiving — not a general fitness tracker with a custom mode.
Auto Jump Detection
Detects boarding, climb, freefall, canopy, and landing automatically. No button pressing, no setup. Just put your watch on and jump.
Freefall Altimeter
Large altitude display in thousands — 13.1, 7.5, 4.5. White on black, nothing else. Safety callouts at breakoff, pull, and hard deck.
Canopy Navigation
Compass arrow pointing to the DZ with distance in yards or metres. Two display modes — standard view and arrow-focus for critical approach.
Audio Coach
Spoken altitude callouts, heading guidance, and drift warnings through your AirPods. Three profiles: Quiet, Standard, and Full Coaching.
Exit Separation
Live group separation timer based on aircraft ground speed. Know exactly how long to hold before your group exits for safe separation.
Metric & Imperial
Full support for feet/metres, miles/km, and yards/metres throughout every screen. Switch in settings — takes effect immediately.

Jump Counter Widget
Watch face complication showing your total jump count. Glance at your wrist between loads — no need to open the app.
Auto Upload
Jump data syncs to your Cloudbase logbook automatically via your paired iPhone, direct WiFi, or cellular. On Apple Watch with cellular, your logbook updates even if your phone is back at the hangar.
No setup required
Open the app, select your DZ, and it handles the rest.
Select your drop zone
The watch finds nearby DZs using GPS. Tap yours and you're ready.
Wear it and jump
Detection starts automatically. Boarding, climb, freefall, canopy — all tracked without a tap.
It syncs itself
Jump data flows to your Cloudbase logbook the moment you're back in range. Nothing to export.
