Pro Dive

Pro Dive transforms your Apple Watch Ultra into a full-featured dive computer.

Pro Dive continuously tracks your depth, time, ascent rate and tissue loading to keep you informed throughout every dive.

Real-Time Dive Computer • Certified to EN13319 — the international standard for dive instruments. • Live depth display • No-Deco Limit (NDL) • Decompression ceiling and Time-To-Surface (TTS) estimates • Gradient Factors and multi gas support (Nitrox / Trimix capable engine) • CCR support with fixed PPO2 and Bail Out modes • Ascent-rate tracking with smart averaging • Automatically detects submersion and starts logging • Underwater Compass • Indicates no fly time

Decompression Model

Built on the Bühlmann ZH-L16C model with gradient factors, Pro Dive continuously updates a full 16-compartment tissue model during your dive — just like a dedicated dive computer.

Automatic Dive Logs

Every dive is saved automatically and synced to your iPhone: • Full dive profile graph • Max depth, duration, start/end times • Min/max temperature • Location via GPS + reverse geocoding • Notes and dive-day details • All logs stored locally with optional cloud backup (if applicable)

Designed for Apple Watch Ultra

Pro Dive is built specifically for the Ultra’s: • Depth and water-temperature sensors • Bright always-on display • Large Action Button and crown to quickly select options underwater • Rugged dive-ready design

Offline, Reliable, and Fast

All calculations run entirely on the watch — no signal required. Your watch keeps logging even if the iPhone is not nearby.
