  • Worst than useless!

    I wish I could get my money back. Can't use it to calculate Boyles law. PSI only goes up to 100, why??
  • Fix submitted

    @Penn hit the lock icon for the one you want to calculate (that is, "unlock" the one you want to solve for), then move the sliders of the other 3 values to calculate - it computes as you make the changes. See my support site for a video example!
  • Can't seem to get it to work!

    Trying to experiment with changes in volume, temp and pressure and I don't seem to be having any luck. Better instructions may help!
  • Good idea except

    At least in iOS 7, I'm unable to scroll back up to the top of the calculator, making it useless. :(
  • Finally.

    Worked great for me. Had no trouble with the app. Not sure what "agrenergy" or "mommum" had a grief about. The sliders make it better than the other ones I've tried.

    Update has finally fixed the keyboard thing so I can enter values numerically.
  • Nononono

    Doesn't work
  • Worthless!

    Don't waste your time!
  • Sort of works

    Easy to get wrong results as values don't always update reliably. Wouldn't recommend.
  • Doesn't deliver.

    I'm a first year gas student for commercial applications and I must say this calculator doesn't deliver clear results. For 99 cents I thought I was getting something that would be easy to work with and displayed the results. Instead I find myself trying to make sense of it all. This calculator needs instructions and a second window that displays the reasoning behind the answer. And display the formula.

  • Great App!

    Really like this app. Numerous input options for each entry. I like the sliders for manipulating the calculations...allows for quick variances in results. Good job!
