Want to refresh your memory on named chemical reactions before an exam or a group meeting? Get all the details with ReactionFlash(R) as a great way to learn named reactions, understand their mechanisms and view examples published in peer-reviewed literature. Designed and developed in consultation with Professor Dr. Erick M. Carreira of ETH Zürich, the app covers 1'266 named chemical reactions, by far the largest collection of Named Reactions. Professor Carreira has helped ensure that we have all the fundamental reactions that should be part of every chemist’s toolkit: from the best-known ones to the ones only Nobel Prize winners remember! The app is designed like a set of flash cards so it can be used as a learning tool as well as a reference. Each ‘card’ shows the reaction, its mechanism and examples from peer-reviewed, published literature. It also has a quiz mode that lets you test your knowledge. Linking into Reaxys enables you to find the most recent examples of each reaction, many with experimental details. Reaxys delivers experimental facts from the literature, enabling researchers to find the best synthetic routes and conditions.

Our free Vernier Instrumental Analysis™ app makes it easy to incorporate instrumentation into your chemistry curriculum. The user-friendly interface walks students through the data-collection process and includes instrument-specific analysis features. Collect, analyze, and share data from our Mini GC™, Mini GC Plus, Go Direct® Mini GC, Go Direct Polarimeter, and Go Direct Cyclic Voltammetry System with this free app. Students can collect a gas chromatogram from the Vernier Mini GC, Mini GC Plus, and Go Direct Mini GC. They can also determine peak area and integrate peaks. Using Go Direct Polarimeter, students can collect polarimetry scans and optical rotation data for individual samples, as well as over time. The mutarotation kinetics of sucrose has never been easier to observe. If students have the Go Direct Cyclic Voltammetry System connected, they can easily collect voltammograms to analyze current peaks and determine standard potentials of electrochemical reactions.

Verdict
The clearest difference is update cadence: ReactionFlash at every 4 months against Vernier Instrumental Analysis's every 12 months. ReactionFlash also leads on iOS requirement (14.0 vs 16.7.8). On price, ads, in-app purchases and device support there is nothing between them.
