Beginning chemistry students can use this app to visualize the mathematical relationships occurring between substances in a chemical reaction.
Get a feel for limiting reactants and how they affect product formation. Analyze mass relationships and apply this logic when solving stoichiometry problems.
The user-friendly interface of the “Simulator” allows you to quickly set the desired reactant masses and run multiple trials in a short period of time. Choose from a variety of reactions.
Click over to “My Trials” to view past trials, make comparisons, or plan future trials.
The “Lab Manual” currently has three activities that will help you better understand the role of limiting reactants, mass relationships, and balanced equations.
Use the simulator to quickly generate your own practice problems to reinforce the concepts. Set up the masses, run the trial, record the results. Then, use one or more of the amounts to set up a variety of problems…the best part is you’ll already know the answer!

Great for Learning
This app is great for *learning* the core concepts behind stoichiometry. Not sure why someone taking a 300 level chemistry course would need to use it other than the fact they wanted it to do their homework. This app doesn't promise to do your work - it helps you understand what's going on so you can do your own work. The only reason I wouldn't give it 5 stars is because it would be nice to have the ability to do custom reactions. The four reactions it does have show what happens when you have a 1:1, 1:2, 2:3, and 3:4 relationship between your reactants. I wonder how many people catch that? Looking forward to an update.
Not worth $0.01
Seriously? Four reactions is a joke. Good looking, though. Useful for about 2 minutes. I'm taking a level 300 chem class and wanted something useful for class, so I purchased this app. Unfortunately it really is not anything it could be. If your looking for a faster way to get stoichiometry problems done... get a tutor at your center for academic success because this app is a bummer.
Needs a little more
As a high school science teacher I like the app but it needs something added to it. You should be able to enter an unbalanced equation and then have the app balance it and then have it placed into the current app window.
