ReactionAtlas

ReactionAtlas puts 250 classic named reactions of organic synthesis in your pocket — fully offline, no account, no ads. BROWSE BY MECHANISM FAMILY Reactions are organized the way mechanisms actually work: Polar, Organometallic, Pericyclic, Radical, Carbene, Concerted, Photochemical. Full-text search across names, net transformations, and reagents. Star your favorites. RICH REACTION NOTES Every reaction includes its net transformation, controlled-vocabulary tags for category, mechanism, key intermediates and reagents, a reaction scheme and curly-arrow mechanism figure (from Wikimedia Commons, credited in-app), a concise mechanism walkthrough, an overview, and real synthetic applications from total synthesis. THE ATLAS An interactive force-directed map of the whole field: reactions cluster by shared mechanism and identical net transformation. Pinch to zoom, tap any node to jump to its note. Each note also carries its own radial "ego network" — same mechanism, same transformation, shared intermediates, shared reagents — so you can walk the web of organic chemistry one hop at a time. FLASHCARDS Quiz yourself from the transformation and reagents, reveal the answer, and track what you have mastered. Progress stays on your device. OFFLINE AND PRIVATE Everything is bundled. The app never connects to the internet and collects no data whatsoever. FREE AND PRO Every reaction's scheme and curly-arrow mechanism is free, forever. A single one-time purchase (ReactionAtlas Pro) unlocks the overviews, synthetic applications, mechanism insights with extra figures, the interactive atlas, and the flashcard quiz. No subscription. Made for students preparing for exams, researchers at the bench, and anyone who loves the logic of organic synthesis.
