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

Version History - The CCR table can now also show the diluent as open circuit: PPO2 and gas density of the unchanged diluent, i.e. the bailout case
- Limiting depths are listed separately for loop and diluent
- Depth steps are only coarsened where the finer step adds nothing 2.0.38 Aug 27 - Depth tables: headings stay in view, 3 m steps, coloured row shows the limit
- Tables scroll properly on phones again
- CCR table marks the diluent range and setpoint reachability
- Gas density now states its reference temperature, consistent °C/°F
- Clearer message when a mix is impossible, readable in dark mode 2.0.37 Aug 26 - Reworked gas limits by depth: oxygen partial pressure, narcotic depth and gas density in one place, showing which limit comes first
- Rebreather screens now calculate the loop gas you actually breathe, and warn when the supply gas cannot sustain it
- Corrected the depth calculation: 1 bar is no longer treated as 1 atmosphere
- All texts are now available in all five languages 2.0.35 Aug 17 - Isochore: new help text explaining temperature compensation
- Isochore: the measured temperature is no longer corrected silently, and the slider now covers the whole measurement range
- Isochore: the measured temperature is no longer kept for the next time
- Settings: the controls are now real buttons and work better with screen readers 2.0.34 Aug 15 - Fixed the dark mode: notification messages and some buttons no longer show up in light colours 2.0.33 Aug 13 - New dark mode: choose the colour scheme manually or let it follow your system setting
- Redesigned Topoff legend diagram, now readable on narrow screens
- Corrected translations in several places
- Updated the About page
- Modernised the technical foundation for better performance and stability 2.0.32 Aug 12 - Fixed status bar spacing/layout issue 2.0.30 Aug 10 The latest update for Blender Toolkit now includes a feature that allows you to copy the results of your calculations to the clipboard for easy pasting or sharing. 2.0.26 12/17/2023 compiled with current xCode 14.2 version 2.0.24 01/04/2023 The default value of the showSliders option has been changed to false. 2.0.23 01/03/2022 added tank capacity selector in imperial units 2.0.22 01/02/2022 Factory setting for used gas calculation model has been changed from "ideal gas" to "real gas vdW" 2.0.19 08/21/2020 minor UI improvements on page "topoff" 2.0.18 04/06/2020 minor UI improvements 2.0.17 01/20/2020 Fixed price setting for nitrogen on page "Continuous blending (Delta gas)" 2.0.15 11/24/2019 New feature: Quick selection of the volume of the scuba tank. The set of volumes used can be configured in "common settings" 2.0.13 11/19/2019 Change: "Gas Density" column is displayed in both display modes (normal and verbose)
UI: fixed text selection on getting focus field 2.0.9 11/13/2019 New feature: Added CCR rebreather diluent END calculator for different depths with a chosen PPO2 setpoint 1.0.7 08/09/2019 Standard gas list order by O2, He
