Gas Blender Toolkit vs ToolsX

Gas Blender Toolkit is a comprehensive, purpose-built calculator for technical and recreational scuba divers who blend their own breathing gases. FUNCTIONS • Partial-pressure gas blending with freely configurable fill order • Continuous / delta-gas blending method • Decanting from a storage bank, with calculation of the number of possible fills • MOD / END tables for standard scuba gases • pSCR loop oxygen-reduction calculation at constant volume ratio • CCR rebreather diluent END calculator for any depth and chosen PPO2 setpoint FEATURES • Real gas (Van der Waals) or ideal gas calculations • Cost calculation for each gas fill • Fully customizable standard gas list • Accounts for gas heating during filling • Clean, fast and easy to use • Available in English, German, Russian and Spanish Gas Blender Toolkit is the completely rewritten successor to the DIR-Wetnotes app, redesigned from the ground

ToolsX is the gas calculator for technical and recreational diving: plan the right mix, check safety limits and get the exact blending recipe, all in one beautifully designed app. GAS PLANNER • Automatic nitrox or trimix recommendation from depth and max ppO2 • Live MOD, END, ppO2 at depth and gas density • Density warnings (5.2 and 6 g/L thresholds) and mix depth ceiling • Manual trimix analysis with free O2/He input and "oxygen is narcotic" option MIX RECIPE • Enter your starting and target mix: the app computes the exact helium, oxygen and air additions • Fill sequence picked automatically from all 6 permutations to minimize the transient ppO2 peak • Step-by-step breakdown with tank pressure and ppO2 after every addition BLEND STUDIO • Direct partial-pressure trimix blender • Step blending mode (add He, O2, air) with final mix and ppO2 peaks • Manual sequence override when you need it PRESETS • Save and recall complete gas, tank and blending setups • Metric (m, bar, L) or imperial (ft, psi, ft³) units with automatic conversion Italian and English interface, instant calculations as you type, Liquid Glass design built for iOS 26. Note: ToolsX is a planning aid. It does not replace technical training, gas analysis procedures or your dive computer. Always dive within the limits of your certification.
