Best Organic Chemistry App. I justed finished all the levels and they were amazing. The last level especially was exhilarating. And it would be better is transition states are shown in dotted bonds. And need more reactions. Like canizarro Williamson hvz and alpha carbon chemistry

Nice so far, even though I'm only at the beginning. Two things: introduction, chapter 8, question 2. A ball flying trough the air has potential energy as well as kinetic energy. Ionic bonds, chapter 1, last question: "When Cl gives up its electron it becomes..." but Cl does not give up its electron (and even if it did it would become Cl+, but the answer you suggest is Cl-).

Great learning tool I really enjoy using this app. The gen chem section is great to freshen up and review core chemistry principles. The mechanisms in the organic chemistry section have good explanations and I feel like I'm actually learning and not just memorizing steps. Highly recommend to anyone who needs a little extra study practice or just wants to refresh their memory on principles and reactions.

Mistake I'm a senior chemistry teacher going through the questions as I was thinking of using it for my courses. Introduction chapter 8 asks the SI unit for energy. Though it says "calorie" the correct answer is the Joule. Please change this. I'm going to check out other sections on a casual basis and update if I see errors.

Awesome app I have had so much fun using this app. Very helpful. I think it is in chemical reactions chapter 14, some of the questions could be worded more clearly. Such as in a balanced equation, the reactants should change, Thats how you get a product. The number of each element should stay the same.

Quality and TOTALLY FREE App! They DO EXIST! This is a great example of how to positively impact education and help society grow. I highly recommend this application and the developer. My message to them; Dear Electrolyticearth Developers; I felt the need to pass on my sincere gratitude for your Chemistry Lab App! These days I've found that it is so very rare to find a great educational application available to download free that doesn't, in some way, ask for some compensation! Greed pervasiveness seems omnipresent, but here is a great example of how the world could be better. I appreciate the effort, time and dedication it took in creating this application...my appreciation grew exponentially after I saw that the app was completely free of ad's, in-app purchases and Spyware/Adware. Great Job, I hope to see more of the same exceptional applications from you and your example. With the Highest Regards ~ B. Littleton
