## What is Scuba Deco Planner?

Deco Planner brings full Bühlmann ZHL-16C + Gradient Factors decompression
planning to your pocket — fully offline, on the boat or off the grid.

PLAN — depth, time, gas and tanks in a few taps
SAFETY — 13 automatic checks: gas shortage, O₂ toxicity (ppO₂/CNS/OTU),
narcosis (END), gas density, exceeding M-values, ICD and more
INSIGHT — see the ceiling, when deco begins, and tissue-pressure graphs
CONTINGENCY — a ±6 m × ±10 min matrix with warnings, computed in advance
UNDERWATER — a high-contrast slate card with TURN and MIN GAS oversized
TEAM — share the whole plan as a QR code; any camera app can read it

Important: this app is for education and plan exploration. It is not a
substitute for training or a dive computer. Always follow your agency's
procedures and dive within your certification.
