Master organic chemistry anywhere. Octet is the offline-first study companion built for undergraduates, pre-med, and pre-dental students preparing for MCAT, DAT, and college exams. No subscriptions to start. No ads. No account. No internet required. Everything lives on your device. WHAT'S INSIDE 80+ Organic Chemistry Reactions SN1, SN2, E1, E2, EAS, SEAr, Grignard, Aldol, Wittig, Diels-Alder, Claisen, and more. Every reaction with tappable step-by-step mechanism viewer showing electron flow, bond breaking, and bond forming. 25 Functional Groups Alkanes, alkenes, alkynes, alcohols, ethers, amines, aldehydes, ketones, carboxylic acids, esters, amides, nitriles, and more. Each with SMILES structure, IR frequencies, NMR chemical shifts, and pKa data. 60+ Reagents Searchable reagent lookup. Oxidizers, reducers, catalysts, protecting groups, nucleophiles, electrophiles. Full usage notes and typical conditions. Quick-Reference Tables pKa values. IR spectroscopy frequencies. ¹H-NMR and ¹³C-NMR chemical shifts. Designed for instant lookup during problem sets. STUDY TOOLS Flashcard Mode Swipe through reactions and functional groups. Mark as "knows" or "learning." Progress persists locally. Built for spaced repetition workflows. Comparison Mode Side-by-side reaction comparison. See how SN1 differs from SN2, E1 from E2, at a glance. Fuzzy Search Search reactions, reagents, and functional groups by name, type, or transformation. Typo-tolerant. Bookmarks Save favorite reactions and reference cards for instant recall. Dark Mode Easy on the eyes during late-night study sessions.
