A barometric skydiving altimeter for your Garmin watch — a big AGL readout, automatic zeroing, a DZ arrow, and a jump logbook.
The only one of its kind
No automatic zeroing. And a barometer smoothed so hard it can read 1,800–2,500 m at a 700 m canopy opening — sometimes still showing exit altitude after you’ve landed.
AltiFenix reads the raw pressure sensor and zeroes itself to the ground, automatically — so the number is right from exit to touchdown. It’s the only altimeter on Garmin that actually does the job.
Everything on your wrist
Every screen below is the real app, running on a fēnix 8.

AGL in the L&B Viso format — kilometers up high, meters down low, switching automatically at 1,000 m. Readable at a glance under stress.

Read it your way — the same jump in metric or imperial, set once and forgotten. That 4.20 km reads 13.8 up top, feet all the way down.

No fiddling on the load. AltiFenix finds ground level automatically and holds it — even if you forget to open the app before takeoff.

It picks your drop zone from your location, so ground elevation is right wherever you jump. Set a landing offset by hand when you need to.

Vibration alarms you set per phase — climb, freefall, canopy. A pulse on the wrist at break-off, at your hard deck, wherever you want one.

Every jump logs itself: exit and deployment altitude, freefall time, canopy time, and a running lifetime count — no buttons to press.

Scrub the whole descent after the jump — altitude and vertical speed over time, exit to deployment, right on the watch.

A dedicated wingsuit mode with its own detection, so a mellow flocking exit still logs as the flight it was — not a missed skydive.

Once you’re open, the readout adds your vertical speed — spot a fast spiral or a long spot at a glance on final.
One glance in the air
The in-air screen layers the awareness you want without ever crowding the altitude.
And the small things that matter
AltiFenix is not a primary altimeter. It’s a backup and awareness aid. Always jump a certified visual altimeter, an audible, and an AAD. Barometric readings can lag or be wrong — the responsibility for your dive stays yours.
Garmin doesn’t allow skydiving apps in the Connect IQ store, so AltiFenix is installed directly — independent, and answerable only to the jumpers who use it. Setup takes a couple of minutes over USB; the guide walks you through it.
