## What is Diver Planner?

Serious dive planning, from your first to your deepest.

Diver Planner brings dive planning, logging, trips, gas blending and safety info together on mobile — and imports your Shearwater dive computer logs. Grow from your first nitrox dive to trimix decompression in one app.

■ Decompression
· Bühlmann ZHL-16C with Gradient Factors (adjustable GF Low/High)
· VPM-B bubble model
· Multi-level profiles, multiple gas switches (nitrox, trimix & CCR)
· Automatic deco schedule, TTS, CNS%, OTU and gas consumption
· Slate (wetnotes) view, detailed report, and PDF briefing export

■ Dive Replay (new)
· Replay nitrogen & helium saturation across all 16 compartments over time
· Track GF, PPO₂ and ascent rate at every point of the dive

■ Gas Blender
· Step-by-step O₂ / helium / top-off procedure to reach a target mix
· MOD, END and gas-density (CO₂ retention) warnings

■ Dive Log & Trips (trips new)
· Import logs from your Shearwater dive computer (Garmin .fit share supported)
· Group multi-day diving into one trip — site map, stats, repetitive-dive carryover
· Transmitter pressure, tissue saturation and average RMV, tracked automatically

■ Safety first
· Gas-supply, fast-ascent and decompression warnings at planning time
· Built-in DAN emergency hotline, per-country emergency numbers and recompression chamber contacts
· Available in 9 languages (English, Korean, Japanese, and more)

■ Cloud Sync & Sharing (optional)
· Sign in to securely sync plans, logs, trips and settings across devices
· Send a plan to a buddy with a share link
· Works fully offline without an account

Diver Planner is not a medical device and does not replace a real dive computer. Always dive within your training, certification and equipment limits.
