## What is Neutral Buoyancy Simulator?

Neutral buoyancy is the skill that defines a good diver — hovering effortlessly, moving nothing but your breath. Neutral Buoyancy Simulator lets you practice that skill anywhere, on your phone.

Built by a certified scuba instructor, the app models real buoyancy physics: your lungs provide fine control, your BCD provides coarse trim, and depth changes gas volume exactly the way Boyle's law says it should. Slide to breathe, tap to inflate or vent, and feel how a real diver finds neutral.

WHAT YOU CAN PRACTICE
- Basic Mode — learn breath control and BCD trim, and hold steady inside the target ring
- Casual Mode — explore the ocean, free netted marine life, clean up litter, and fill your marine codex
- Breath Control — change depth using nothing but your lungs
- Hover Challenge — random targets that sharpen reaction and precision
- Weight Adaptation — re-trim fast when your load suddenly changes
- Deep Dive Simulation — a full 30 m profile with descent, ascent-rate control, a simulated no-deco limit and a 5 m safety stop

UNDERSTAND YOUR PROGRESS
Every session ends with detailed analysis: breathing rhythm, trim accuracy, depth curve, gas use and coach-style suggestions. Records and personal bests help you see yourself improve.

FOR EVERY DIVER
Perfect for Open Water students preparing for their course, certified divers keeping skills sharp between trips, and anyone curious about how divers float.

Free to download: Basic Mode and Casual Mode are fully free, and every advanced mode includes a free try. A single one-time purchase unlocks everything — no subscription, no auto-renewal.

IMPORTANT
This app is a learning aid. It does not replace professional scuba training, real equipment practice or instructor supervision. Always dive within your certification and follow your training.
