"Awesome" writes a reviewer! More reviewers comments! "I have used it for all of my exams so far and it is extraordinarily helpful." "This is the best investment that you can make to visualize the reactions. There are a ton of them and they are AWESOME!!!!!" Another reviewer writes “Covers all of the major topics and the videos help me visualize the details of the molecules and reactions”…“Could almost replace a whole textbook.” While we never claim to cover an entire organic chemistry class, with content added in each update (major free updates each year since publishing ten years ago!), Tap OChem is the app that delivers! The reactions and concepts included are many from the one year sequence of undergraduate organic chemistry that is offered at all major colleges and universities. Students have told us that this app was essential in their preparation for the MCAT. Whether you are currently in the one year sequence of classes or reviewing for the MCAT, or PCAT, OAT, and DAT, this app will help! Designed by two award winning chemists with over 48 years of combined experience teaching at major universities, Tap OChem makes organic chemistry reaction come to life for each included reaction or concept. The following animations are currently included: Substitution reactions (20 animations), Elimination reactions (11 animations), Alkene Chemistry (15 animations), Free Radical Chemistry (4 animations), Alkyne Chemistry (7 animations), Epoxide chemistry (4 animations), Benzene chemistry (10 animations), Diene Chemistry (8 animations), Carbonyl Chemistry (8 animations), Major concepts (62+ animations), and Molecules in Motion (35+ animations). The Concepts section includes valence bond theory, molecular orbital theory, electrostatic potential maps, radical spin density maps, alkene stability, dienes and stability, conformational analysis of alkanes and cyclohexane, etc. We've just started adding information on intermolecular interactions and plan on more spectroscopic topics! One animation on dipole/dipole attraction was added. Two animations, one focused on the introduction to IR spectroscopy are included. We are developing and updating more animations for future updates! Each animation has an accompanying text that drills down to the main facts of each reaction or concept. These are in FULL COLOR! They are short, handy, descriptions with important information regarding each reaction or concept. In the case of reaction animations, the concise scrollable text descriptions include electron pushing. We will continue to update the app with future releases. Tap OChem is native to both iPhones and iPads! In addition to the animations being very sharp on your iPhone and iPad, they are of excellent quality when projected (iPhone 4S and iPhone 6s, 6s Plus, 7, 7 Plus, 8, 8 Plus, X, 11, 12, and later, iPad 2 and later, using appropriate adapters) in a classroom. For the iPhone 6s and later; and iPad Air 1 and 2 and later, an appropriate adapter is needed like Lightning Digital AV Adapter (this is an HDMI adapter), or a USB C to HDMI adapter, or a Lightning to VGA Adapter.

It covers a wide breadth of organic chemistry content that has been taught in my college course. The 3D animations make chemistry accessible for me. ### 2/5 — Useful *2017-07-11* There are many things this app is lacking. Very, very useful for the information it does cover. And the 3D explanations w/ narration are great. But again, this app lacks other very important key subjects within Organic Chemistry. If it was more detailed, especially pertaining to college level curriculum, would be a fantastic app. ### 5/5 — The best!!!!!! *2016-02-24* This is the best investment that you can make to visualize the reaction there ton of them and they are AWESOME!!!!!! ### 5/5 — Awesome app for students and faculty!!! *2015-03-30* I have used this in class for a few years now and recommend it to all my students. ### 5/5 — 3D vids! *2014-08-11* These 3D videos are VERY helpful for me! App is awesome. I do wish the narration would override my sound being on vibrate so I could still hear. I have to make sure my sound is on in order to hear, to which I'm not accustomed. It was extremely useful in the studying of MCAT materials.👌😃😄 ### 5/5 — Incredible *2014-03-05* This application is essential for anyone studying organic chemistry. All the reactions and concepts are organized to make everything easily accessible. Being able to watch the molecules move and transform helps tremendously in understanding the reactions. Thus, I highly recommend this app. ### 5/5 — Awesome! *2014-01-17* My professor wrote this app. I have used it for all of my exams so far and it is extraordinarily helpful. Definitely a must buy if you are a visual learner. It shows step by step how molecules are formed. It's great for all of the tough reactions that are confusing and have multiple steps. ### 5/5 — Most helpful organic chem app available *2013-12-31* This app covers all the major topics, and the videos help me visualize the details of molecules and reactions. Incredibly high quality and FULL of info. I recommend to anyone taking organic or reviewing for the MCAT. Totally worth more than 99¢. Could almost replace a whole textbook. ### 5/5 — Tap Ochem rocks! *2012-12-16* I find this app one of the most useful I have ever bought. Worth much more than the .99 cost for the visualizations alone. ### 5/5 — Professor *2012-12-03* All organic students should download this app! Super useful!! ## Frequently asked questions about Tap OChem ### What is Tap OChem?

It animates the interactions between ethane molecules. We updated the pKa table and the typical bonding table in the reference section. We fixed an error in our sp and sp2 hybrid orbital animations with too many electrons in the starting atomic orbitals. Enjoy! ### 4.73 — 2023-01-15 We added a new animation on Alcohols Reactions with Hydrogen Halides. It summarizes the different reactivities based on alcohol substitution including reaction rate equations and reaction coordinate diagrams. We did fix a few minor typos as well! Enjoy! ### 4.72 — 2022-10-09 We added two new animations: 1. Dipole/dipole attractive forces between molecules and 2. Radical hydrobromination addition of alkenes! We improved one animation by incorporating electrostatic potential maps: SN2 Run with R-X, Electron Pushing. We did fix a few minor typos as well! Enjoy! ### 4.71 — 2021-09-16 All 170+ animations and accurate descriptions of organic chemistry concepts, reactions, and molecules, from earlier versions are present. We've added one animation on the acidity of alkanes, alkenes and alkynes. This animation is another way of explaining hybridization of hydrocarbons vs. acidity. We also tweaked some information screens to fix minor typos. ### 4.70 — 2021-05-30 All 170+ animations and descriptions of organic chemistry concepts, reactions, and molecules, from earlier versions are present. We've tweaked one animation and added four new animations with the aromatic heterocycles pyrrole and pyridine. The animations show the flat geometries of the heterocyclic and their electrostatic potential maps. The narrated animation in concepts section on IR spectroscopy now includes sound. ## Apps similar to Tap OChem | App | Rating | Price | Category | | --- | --- | --- | --- | | [Khan Academy](https://appshunter.io/ios/app/khan-academy/id469863705) | 4.6 (109,022) | Free | Education | | [Chem AI - Chemistry Solver](https://appshunter.io/ios/app/chem-ai-chemistry-solver/id6471891010) | 4.4 (816) | Free | Education | | [Chemistry Solver: AI Scanner](https://appshunter.io/ios/app/chemistry-solver-ai-scanner/id6736952750) | 4.6 (140) | Free | Education | | [ModelAR: Organic Chemistry](https://appshunter.io/ios/app/modelar-organic-chemistry/id1438760201) | 3.5 (11) | Free | Education | | [Mechanisms: Organic Chemistry](https://appshunter.io/ios/app/mechanisms-organic-chemistry/id1157056029) | 3.2 (67) | Free | Education | | [AI Chemistry Solver: Homework](https://appshunter.io/ios/app/ai-chemistry-solver-homework/id6695725817) | 4.2 (31) | Free | Education | ## More apps by Tap OChem, LLC - [Tap OChem Lite](https://appshunter.io/ios/app/tap-ochem-lite/id763895340) All apps by Tap OChem, LLC: https://appshunter.io/developer/579861209 ## Related topics [tap ochem](https://appshunter.io/ios/topics/tap-ochem) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
