Earn bronze → platinum trophies, celebrate perfect runs with stars, and track accuracy by category. Come back daily to keep your streak alive.

• Built-in help, right where you need it
Priority tables (suffix/prefix), common substituents, alkane parent names, stereochemistry tips, and worked examples pop up exactly when they’re relevant.

• Designed for iPhone & iPad
Beautiful in light or dark mode, portrait or landscape. Study offline anywhere—no sign-in required. Fully localized in 16 languages.

• Coverage you can trust
Alkanes → alkenes and beyond, plus heterocycles, stereochemistry, and biochemistry-inspired names—continuously expanded and refined.

Perfect for high school and college courses, a quick refresher for researchers and instructors, and focused prep for exams like AP/IB, ACS exams, GRE subject material, and MCAT chemistry components. (Not affiliated with any testing organization.)
