About
Barefoot Blender is a gas blending and dive planning toolkit for trained scuba divers, technical divers, and fill station operators.
Use it to plan Nitrox and Trimix fills, estimate top-off outcomes, compare gas sources, calculate fill costs, and check MOD, EAD, END, best mix, and gas density.
Safety. Barefoot Blender is for trained divers and fill operators only. It is not a substitute for formal training, agency procedures, shop policy, or calibrated gas analysis. Always verify final oxygen and helium content with calibrated analyzers before diving or labeling cylinders. Incorrect gas blending can cause serious injury or death.
Subscription. Barefoot Blender Pro is an annual subscription. Payment is charged through your Apple account. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. You can manage or cancel subscriptions in Apple account settings.
