Medical gas and oxygen: levels, burn rate, hours remaining.
Liquid tanks, cylinder manifolds, PSA plants and concentrator banks, each with its capacity and its critical mark. Levels are recorded against a source, and the board computes the only number that matters at 2 a.m.: hours remaining at current burn, worked out on every load and stored nowhere, with the sources under their critical mark first.
What it does not do, by design. A listing with only benefits is an advertisement.
Read out of the code, not the brochure: each app below is here because one service queries the other’s tables. Install either side and the hand-over is already wired.
