"Awesome" writes a reviewer!

"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!!!!!"

With over 3 hours of video animations, Tap OChem puts organic reactions and concepts at your fingertips!

Quickly understand organic chemistry with over 130 animations of the most important concepts and reactions! Critical in prepping for the MCAT, PCAT, GRE, OAT, and DCAT.

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.”

With content added in each update (one major update each year for the past two years!), Tap OChem is the app that delivers!

The reactions and concepts included are the most common from the one year sequence of undergraduate organic chemistry that is offered at all major colleges and universities. Whether you are currently in the one year sequence of classes or reviewing for the MCAT, PCAT, OAT, or DCAT, this app will help!

Designed by two award winning chemists with over 42 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 (14 animations), Elimination reactions (11 animations), Alkene Chemistry (11 animations), Alkyne Chemistry (6 animations), Epoxide chemistry (4 animations), Benzene chemistry (10 animations), Diene Chemistry (8 animations), Carbonyl Chemistry (8 animations), Key concepts (44 animations), and Molecules in Motion (34 animations). The Concepts section includes hybridization theory and conformational analysis of alkanes and cyclohexane. More animations will be included in future free updates!

Each animation has an accompanying text that drills down to the main facts of each reaction or concept. These are now 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.

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 5, 5s, 6, 6 Plus, 6s, 6s Plus, 7, 7 Plus, and later, iPad 2 and later, using appropriate adapters) in a classroom.

For the iPhone 5 and later; and iPad Air 1 and 2 and later, a Lightning Digital AV Adapter (this is an HDMI adapter), or a Lightning to VGA Adapter is required to connect to a digital projector with HDMI and/or VGA inputs.

For the iPhone 4S, the Apple 30-pin Digital AV adapter (for HDMI) or the Apple 30-pin to VGA Adapter is required to connect to a digital projector with HDMI and/or VGA inputs.

What's New in Version 4.20

We've added three new narrated Diels-Alder animations and tweaked the menu system with more cross referencing! The three new animations are the first three in a series of Diels-Alder animations under development. The animations are: Diels-Alder 1 Fundamentals; Diels-Alder 2 Diene and Dienophile Substituents; and Diels-Alder 3 Dienophiles, Stereochemistry, Endo Rule. Enjoy!

Customer Reviews


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.
