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 clearest difference is review sentiment: SynStrategy at 100% against Organic Chemistry Practice's 0%. SynStrategy also leads on rating (5.0 vs 3.0) and in-app purchases (none vs 1). Organic Chemistry Practice's advantage is update cadence (monthly vs every 3 months) and device support (3 vs 1). On price and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Organic Chemistry Practice sells 1 in-app purchase, starting at $2.49 per month. SynStrategy asks for nothing beyond the download.
SynStrategy holds the better App Store score, 5.0 against 3.0. That said, the two scores are not equally well evidenced: SynStrategy has 10 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 100% of SynStrategy's written reviews are positive against 0% of Organic Chemistry Practice's.
SynStrategy ships an update every 3 months, Organic Chemistry Practice monthly. The most recent releases landed on November 5, 2026 and October 30, 2026 respectively.
