About this app
The most important app for organic chemistry students includes 80 functional groups, the classes of organic compounds (aldehyde, ethers, esters, etc.) and natural products (nucleic acids, carbohydrates, lipids, etc.). Start from the basic groups (such as ketones and hydrocarbons) and proceed to the advanced topics (for example, azo compounds and boronic acids).
Choose the game mode and take a quiz: 1) Spelling quizzes (easy and hard) - answer all questions correctly to win a star. 2) Multiple-choice questions (with 4 or 6 answer options). 3) Time game (give as many answers as you can in 1 minute) - you should give more than 25 correct answers to get a star. Two learning tools: * Flashcards for memorizing these groups. * Tables of functional groups.
The app is translated into 13 languages, including English, German, Spanish and many others.…

Five-star share of ratings
Under 65% five-star
Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.
In the package we scanned
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence about the app, not a finding about it.
