Master organic chemistry reactions with a structured tutor built for Organic Chemistry I and II. Learn how reactants, reagents and conditions lead to products; connect mechanisms with regiochemistry and stereochemistry; then reinforce every topic with guided lessons, mastery checks and targeted practice. Explore 2,164 curated reactions covering the major transformations taught across a two-semester organic chemistry course. START FREE Begin with Alkanes and Free Radical Halogenation at no cost. A single in-app purchase unlocks the complete reaction library and all remaining course content. No subscription. FOLLOW A TWO-SEMESTER COURSE PATH Study Organic Chemistry I and II in a logical sequence instead of memorizing disconnected reactions. Each topic follows three stages: • Understand - Guided lessons explain what changes, why the reaction works, which selectivity rules matter and which common mistakes to avoid. • Master - Complete a focused 10-question mastery check. • Practice - Build fluency with a larger bank of reaction questions. Semester I, Semester II and comprehensive review modules help you connect reaction families and prepare for exams. EXPLORE 2,164 ORGANIC REACTIONS Browse by functional group or reaction family. Review reactants, reagents, products, reaction conditions, selectivity, stereochemistry, mechanism information and detailed reagent notes. STUDY YOUR WAY • Flashcards - Practice reactants, reagents, products or a random mix. • Multiple-choice quizzes - Test reaction recognition and product prediction. • Explore Reactions - Use the library as an offline organic chemistry reference. • Custom drills - Combine functional groups for focused review. • Study packs - Work through curated reaction sets with progressive challenges. • High scores and trophies - Track performance and earn bronze, silver, gold and platinum achievements. CREATE YOUR OWN REACTIONS Add custom reactions and notes to match your course, professor, textbook or problem sets. Build a personal study collection around the chemistry you need most. BUILT FOR SERIOUS STUDY • Guided lessons with progress and mastery tracking • Optimized layouts for iPhone and iPad • Offline access after download • Resume lessons where you left off • Report problems directly from study and lesson screens • One-time Full Access purchase with no subscription Whether you are learning reaction families for the first time, preparing for an organic chemistry exam or reviewing both semesters, Organic Reactions Tutor helps turn memorization into chemical understanding and reliable pattern recognition.

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.

Verdict

The call

The clearest difference is in-app purchases: SynStrategy at none against Organic Reactions Tutor's 1. SynStrategy also leads on ratings volume (10 vs 2). Organic Reactions Tutor's advantage is update cadence (fortnightly vs every 3 months). On price, rating, ads and device support there is nothing between them.
