## What is AltiX Skydiving?

AltiX brings skydiving planning, jump logging, and equipment tools together on iPhone and Apple Watch.
APPLE WATCH ALTIMETER AND JUMP LOGGER
• View a clear altitude display using fused, barometric, or demo mode.
• Automatically calibrate on the ground and detect takeoff, freefall, canopy flight, and landing.
• Record altitude samples and a phase-tagged GPS route.

Completed watch logs sync to the paired iPhone for detailed review. Explore the altitude profile, summary data, and GPS track, with different colors for takeoff, freefall, and canopy flight. Export a raw JSON copy through the system share sheet when you want to analyze or archive your data elsewhere.
WIND-AWARE MAP PLANNING

• Automatic or manual wind profiles let you plan with online data or enter local observations yourself.
ESSENTIAL SKYDIVING TOOLS

• Repack Reminders for multiple rigs, configurable intervals, advance notice, and local notifications.
• Feet or meters for altitude, and kilometers or miles for distance.
