There are many unit conversion apps and there are many calculator apps... There are even chemistry apps and engineering apps... but there is only one Chemical Engineering AppSuite!!!

Chemical Engineering AppSuite for iPad and iPhone has been developed by a team of chemical engineers for both professionals and students. This one-of-a-kind app features many equations and data used by chemical engineers, chemists and other engineers and integrates them with unprecedented functionality! And yes, we have also unit converters and graphing calculators.

The app is also great for any high school or college student in science and math courses. Professionals will also find it very useful!

Anyone with an interest in science, chemistry, math or engineering can find ways to use Chemical Engineering AppSuite HD!

Highlights of the app include:

Full steam table calculations based on IAPWS95 model.

Database with 1000+ common industrial and laboratory chemicals

Unit converters for temperature, pressure, length, area, time, and many, many more. Select your favorites for quick access!

Physical property calculations for more than 1000 compounds and elements including densities, vapor pressures, heat capacities, viscosities.

"ChemE Tools" for rapidly solving problems in fluid dynamics, process controls, mass/mole calculations and combustion reactions!

Periodic table of the elements with a high-resolution, zoomable view

Thermodynamic Equations of State: Rapidly solve for any variable in ideal gas, Peng-Robinson, van der Waals, SRK, and others.

Calculation of compressibility factors and graphing of individual compressibility charts via the Lee-Kesler model

Binary vapor-liquid equilibrium prediction with graphing via Raoult's Law (ideal) or Wilson Model (real). Over 675 pairs possible in the Wilson Model.

Spreadsheet, statistics, and graphing tools with a built in graphing calculator! (iPad only). The iPhone version includes a very useful calculator as well!

Matrix tools and linear equation solvers.

Randomized practice problems for mass balances.

What’s New

Version 3.0.2

This app has been updated by Apple to display the Apple Watch app icon.

Although there has always been a really nice Periodic Table within the iPad version of the app, we've made it much easier to find and use as a PDF. Find it under 'General Info' -> 'Chemistry" on both the iPhone and iPad versions of the app.

Fixed a bug that could cause the app to crash if the user entered invalid value in the Water Vapor Pressure or Air-Ideal Gas modules.

OMG! Best app ever!

As a scientist, I use units, chemicals, and equations everyday. This app has surprised me everyday with something it has that I didn't know about. This app makes it easy for me to do quick unit conversions, learn chemistry, and review science. I love this app and I would highly recommend it to anyone who lives on the planet earth or anywhere in the universe!

Really helps find answers quickly

For getting a quick answer or playing "what ifs", this app works great. A setting to save imperial as a default would certainly be of help. Hoping the next update provides this. My industry is still stuck using imperial units rather than metric.

Very Handy

I used this all through college as a student at The University of Alabama. Now that I’m out and have a job, I find myself still coming back to this app time and time again. It’s great, it’s free, and always very useful in and out of school. If you’re a chemical engineer, this is a must-have
