## Most critical reviews (8 lowest-rated)

### 1/5 — Just wrong

*2013-06-19, version 1.4.1*

I've compared the results with other tables and they are wrong. Wrong enough to not use it for engineering

### 3/5 — Inaccurate

*2012-03-09, version 1.4.1*

The saturation temperatures do not match up with the saturation pressures correctly. A good example is at 27 C. The enthalpy should be ~113 but it is ~123. The app is good for rough calculations. If they fixed the saturation temperatures and pressures then it would be 5 stars.

### 5/5 — Cool App

*2016-02-25, version 2.0.2*

Verified the results and they are correct. Awesome free app 👍👍👍

### 5/5 — Great App!!!

*2012-02-07, version 1.4.1*

As a mechanical engineer, this app really helps and saves me a lot of time.

### 5/5 — Useful for the price

*2012-01-11, version 1.4.1*

Very reliable free app for steam tables

### 5/5 — Great for power plant operators!

*2011-08-01, version 1.4.0*

I use it for telling me what my super heat is at while starting up a power plant. It would be nice if it just told me how much super heat I have. Instead of going off of the heat above saturation temp but it works. Thank you for making the app!!!

### 5/5 — A must for the sociable geek

*2011-03-16, version 1.4.0*

I'm in a bar right now and downloaded this app to calculate the amount of heat removed per gallon of water charged to a Japanese nuke plant.  Nothing impresses the ladies more, btw.  With the help of this fine free app I was able to showcase my engineering prowess and walk away with a girl's number.

### 5/5 — Great app for the price

*2011-02-19, version 1.4.0*

Nice simple app for quick calculations. I wish it had a way to export or email results but other than that, this is fine!
