    Some of us (at least me) would be happy to test out the app a little before Google "approves" it? If you want to share before it hits the shelves....

    Looks really good. On the transfill page, when a result gives "T1", T2" and "Twinset", what exactly are those results? Also, the prompt text on the pressure entry when defining a tank says "Pressure in PSI" even when the option for "Bar" is selected. No big deal, the entry in bar still works just so you have a heads up.

    Thanks for the notice, I'll fix the units.

    It calculates the transfill to twinsets by first filling one half of the twinset and noting the resulting pressure (T1), then taking that as the source fill pressure for the other half and noting that pressure (T2), and then blending T1 and T2 for the resulting twinset pressure.

    Great idea and a nice simple design.

    I have a couple of questions/observations on the App (NOTE: I'm using imperial units and on IOS):

    1. Gas calculation for safety stop seems slightly off.
    For example, using a SAC of 0.7, Safety Stop for 3 min @ 15 ft with SAC multiplier 1.0
    Doing this long hand: 15ft = (15/33)+1 = 1.45 ATA: Gas Consumed = 1.45 * 0.7 * 3 = 3 cuft but the App calculates at 2.6
    Tiny difference, but thought I'd mention it as feedback

    2. I cannot make any changes to the Pressure Sliders in Settings. Whatever value I enter gets changed by the app when I move to a different field. I suspect that when I enter a value in PSI (e.g. 3000 PSI) it converts it to bar (206 bar) and displays the value in bar.
    As a result the values for Gas, Gas Time and RB in the Cylinder section is meaningless (Cylinder spec is HP 100: Imperial, Steel, 100 cuft, Pressure=3440

    Keep up the good work!
