SynStrategy vs ReactionAtlas

SynStrategy is an organic chemistry app for anyone studying or working in organic synthesis. Its key feature is the categorization of named reactions and unnamed chemical reactions by the functional groups they form, helping students and practitioners navigate the vast landscape of organic transformations. The app features 27 main functional group categories, each further subdivided (for example, Alcohols include primary, secondary, tertiary, allylic, and homoallylic alcohols, and more). This structured organization gives chemists a clearer view of available transformations during synthetic and retrosynthetic analysis. SynStrategy currently includes over 500 organic chemistry reactions, with their synthetic use cases highlighted in more than 400 total synthesis examples. NEW: We've added the mechanisms for a collection of classic named oxidation reactions, with more to come. Each mechanism includes literature references you can look up for further detail. The first set covers the Albright-Goldman, Anelli, Babler-Dauben, Baeyer-Villiger, Ball-Goodwin-Morton, Collins, Corey-Gilman-Ganem, Corey-Kim, Corey-Schmidt, Corey-Suggs, Criegee, Dakin, Davis, Davis Asymmetric, and TEMPO oxidations. Beyond the reference library, SynStrategy includes interactive tools to help you study organic chemistry and organize these transformations. Save specific reactions into custom datasets that can be exported and shared with colleagues. Test your knowledge with the app's study modes: a Quiz system featuring three formats with multiple-choice and advanced questions on chemical reactions and total synthesis steps, plus a traditional Flashcard mode. Both modes include session analytics so you can track your progress. NEW: A Statistics dashboard now lets you review your quiz and flashcard results, see what you've studied, and get an overview of your activity in the app over time (More → Statistics). Whether you're preparing for an organic chemistry (orgo) exam, reviewing named reactions and mechanisms, or planning a synthesis in the lab, SynStrategy aims to be a useful organic chemistry companion. There are countless exceptional total syntheses and synthetically relevant methodologies in the literature, and we aim to grow the selection over time.

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.
