## Most critical reviews (10 lowest-rated)

### 1/5 — Worst than useless!

*2015-04-07, version 1,4*

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

### 1/5 — Can't seem to get it to work!

*2014-03-18, version 1,4*

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

### 1/5 — Good idea except

*2013-11-08, version 1.3*

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

### 1/5 — Nononono

*2012-05-02, version 1.1*

Doesn't work

### 1/5 — Worthless!

*2011-04-01, version 1.1*

Don't waste  your time!

### 2/5 — Sort of works

*2011-03-30, version 1.1*

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

### 2/5 — Doesn't deliver.

*2011-02-11*

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.

### 5/5 — Fix submitted

*2014-07-31, version 1,4*

@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!

### 5/5 — Finally.

*2012-08-16, version 1.2*

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.

### 5/5 — Great App!

*2010-08-06, version 0*

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!
