SKUBA — Professional Diving Tools
Essential dive planning and gas management tools designed for use on boats. Built by divers, for divers.
DESIGNED FOR THE BOAT
High-contrast interface readable in direct sunlight. Large, thumb-friendly controls for wet hands. Complete core tasks in under 30 seconds. Works completely offline—no internet required.
TOOLS
BEST MIX CALCULATOR
Find optimal oxygen percentage for your planned depth with built-in safety margins.
GAS ANALYZER (EAD & PPO₂)
Analyze gas mixes at depth. Calculate Equivalent Air Depth and verify oxygen partial pressure stays safe.
GAS USAGE PLANNER
Estimate consumption based on depth, time, and breathing rate. Supports Rule of Thirds and Rule of Sixths.
BREATHING RATE (RMV/SAC)
Track your air consumption across dives. Build history to understand your breathing patterns and improve efficiency.
GAS BLENDER
Advanced partial pressure blending calculator. Generate step-by-step plans using multiple gas banks. Accounts for altitude, temperature, hot-fill compensation, and existing cylinder contents. Perfect for dive shops and technical divers.
GAS MIXER
Calculate resulting mix when combining gases. Verify blending results quickly.
CYLINDER DATABASE
Comprehensive specs for common scuba cylinders worldwide. Searchable by size, material, and pressure.
UNIT CONVERTER
Instantly convert depth, pressure, volume, temperature, and weight between metric and imperial.
FEATURES
- Multilingual: English, Turkish, German, Swedish, Arabic, Russian
- Flexible units: Metric, imperial, or mixed
- Recreational & Technical modes with appropriate safety limits
- Salt water & fresh water calculations
- Built-in tutorials explaining concepts and theory
- Light/Dark/Auto themes
- Completely free, no ads, no subscriptions
WHO IT'S FOR
- Recreational Nitrox divers
- Technical divers managing complex gas plans
- Dive instructors and students
- Dive professionals blending gases
- Anyone wanting to understand dive physics
COMING SOON
Decompression planner, dive logs, and Trimix support in development.
SAFETY NOTICE
Diving involves serious risks. Skuba is for planning and education only—not a substitute for proper training, certification, dive computers, or professional guidance. Always verify critical information with certified professionals. Dive safely.
