Backside Attack vs Learn Organic Nomenclature
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Backside Attack
This educational game helps students grasp fundamental organic chemistry concepts, specifically focusing on the SN2 reaction. It explores key variables like leaving group ability, nucleophilicity, steric factors, and solvent effects to build a strong foundation in chemistry.
- Learn SN2 reaction mechanics
- Explore leaving group ability
- Understand nucleophilicity
- Analyze steric factors
- Study solvent effects
- Earn points with Check Yourself +50
- Unlock Chem Yourself feature

Backside Attack is an educational app targeting students learning organic chemistry for the first time. The game focuses on the SN2 reaction, which is often one of the first reactions students learn when studying organic chemistry. The SN2 reaction is great for educational purposes, as it provides a forum for students to learn about many common variables associated with chemical reactions, such as leaving group ability, nucleophilicity, steric factors, and solvent effects. The Backside Attack project is led by Dr. Neil Garg, an organic chemistry Professor at UCLA. He and six UCLA students (now alumni) devoted countless hours to creating the game flow and all content. The heroic students are: Tara Kappel, Preeya Mehta, William Parsons Stefan Prisacaru, Ernst Schmid, and Justin Soffer. Backside Attack is powered by Element26, Inc., thanks to Dr. Daniel D. Caspi. Students, be sure to: Learn even more and earn points by using the Check Yourself +50 feature on the scoring screen! Unlock the Chem Yourself feature by completing each topic!

Master organic chemistry nomenclature through interactive lessons, molecule-building exercises, challenges, and practice tests. Learn IUPAC naming step by step with over 70 levels designed for high school chemistry, AP Chemistry, and introductory organic chemistry students. Instead of memorizing rules, you'll actively build, analyze, and name molecules yourself in an interactive chemistry training. FEATURES Interactive tutorials that teach nomenclature from the ground up, with a organic chemistry quiz! Over 70 levels covering the organic chemistry nomenclature of hydrocarbons: • Alkanes • Alkenes • Alkynes • Alcohols • Aldehydes • Ketones Learn in both directions: • Match molecules to names • Match names to molecular structures • Draw molecules from given names • Name molecules you create yourself Chemistry tutorials: In levels that introduce new o chem concepts, there are chemistry tutorials explaining you exactly how to master the level. Creative Mode: Build your own organic molecules and let the app generate the correct IUPAC name instantly. Perfect for experimenting, checking homework, or exploring nomenclature rules. Practice Tests: Challenge yourself with tests that help you check your progress and identify topics that need more practice. Visual learning aids: Color-coded highlights show which parts of a molecule correspond to specific parts of its IUPAC name. Use the molecule builder to create a molecule, then see how it is named! Hide names and for chemistry challenges and for additional organic chemistry practice. Planetary Nomenclature Neptune is designed to make learning organic chemistry more engaging, intuitive, and interactive than traditional memorization methods. Additional supported structures include halogen alkanes and carboxylic acids. Ring structures are not currently supported. Whether you're preparing for AP Chemistry, studying organic chemistry (ochem) at school for exam prep or doing university chemistry, or you are simply interested in learning chemical nomenclature, this app provides a practical and interactive way to master IUPAC naming. It's a fun learning game!

Verdict
The clearest difference is rating: Backside Attack at 4.9 against Learn Organic Nomenclature's 4.3. Backside Attack also leads on in-app purchases (none vs 3) and review sentiment (95% vs 81%). Learn Organic Nomenclature's advantage is update cadence (fortnightly vs every 8 months). On price, ads and device support there is nothing between them.

Both are free to download. Learn Organic Nomenclature sells 3 one-off in-app purchases. Backside Attack asks for nothing beyond the download.
Backside Attack holds the better App Store score, 4.9 against 4.3. That said, the two scores are not equally well evidenced: Backside Attack has 74 ratings behind it against 7, so its average is the more settled of the two. Written reviews point the same way: 95% of Backside Attack's written reviews are positive against 81% of Learn Organic Nomenclature's.
Backside Attack ships an update every 8 months, Learn Organic Nomenclature fortnightly. The most recent releases landed on July 4, 2026 and September 14, 2026 respectively.
