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.

Each mechanism includes literature references you can look up (more coming soon) - New: Statistics to review your Quiz and Flashcard results and see an overview of your activity in the app over time - Search improvements, bug fixes, and refinements ### 1.1.0 — 2026-05-04 This release significantly expands SynStrategy’s educational features, transitioning the app from a structured reference tool to an interactive learning platform for students and practitioners of organic chemistry! Custom Dataset Management Users can now curate and manage personalized reaction collections. This feature allows you to save specific transformations into custom datasets as you browse, making it an ideal tool for exam preparation or organizing lecture- or research-specific reactions. • Export & Import: Share your custom datasets with peers or import collections from colleagues, making it easier to study together. Quiz Sessions Challenge your knowledge with a versatile new quiz system designed to test different areas of expertise: • Multiple-Choice Mode: Select from four different options to identify a reaction overview, a reaction name, or the specific reaction used in a total synthesis example. • Advanced Mode: Test your expertise by manually typing in the name of the reaction within a reaction overview or a total synthesis example. • Session Analytics: Pause and resume a Quiz session at your convenience. Upon completion, a detailed review helps you identify areas for further study. • Included Datasets: The app includes pre-installed datasets, allowing you to start practicing with the new Quiz and Flashcard modes immediately. Flashcard Mode Select between three formats and use traditional study cards in the new Flashcard function to review reactions. Like the Quiz sessions, Flashcard sessions can be saved, resumed, and reviewed. ### 1.0.1 — 2026-01-28 Small Corrections: Fixed 3 chemical structures and added missing reference for 1 total synthesis example.  Bug Fixes: Resolved a rare "ghost image" issue when zooming in/out of full-screen images.
