Pressure and Analysis in One App for Gas Blenders
An app that brings fill pressure and gas analysis together, so a blender no longer works across two screens and a calculator.

Blending gas is arithmetic you do with wet hands beside the fill station. Read the analyser, type the values across, fill, measure again. For one set that is fine; for an afternoon of filling it becomes error-prone.
Blend Junk removes the step in between. You connect your analyser to the app and never type a value by hand again.
What that saves
The app reads your O₂ and He values directly and calculates the MOD from your ppO₂ limit. Enter your start pressure and target mix and it tells you exactly how much of each gas to add, and in what order.
No transcription means no transcription errors. And in gas blending a typo is not a cosmetic problem.
Who gains most
Anyone who fills a lot. A fill station, or somebody mixing for a team, wins the most time here — and runs the least risk of a wrong mix from a mistyped number.
