Estimated revenue
A model estimate with a likely range, not a reported figure.
No estimate. Apps outside the grossing charts, and some countries, have no reliable rank-to-revenue curve, so we show nothing rather than a guess.
How this estimate is made
Rank: we take the app's best Top Grossing rank on the latest chart day. Category ranks are converted into an equivalent overall rank, because a #10 in Finance earns far less than a #10 overall.
Curve: that equivalent rank is read off a rank-to-revenue curve anchored on public company revenue and market-data reports for the US iPhone App Store.
Country: the curve is scaled per country (Japan is roughly a third of the US, Türkiye under 1%). Where we have no scale, such as China, there is no estimate.
Range: the likely range widens with country, category and chart depth. It is a plausible span, not a statistical confidence interval.
Not included: ads, payments outside the App Store, and any difference between gross sales and what the developer keeps. Low confidence means indirect data; medium means several independent sources agree.

About this app
Text from the App Store listing.
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. So you can learn the names of the functional groups in any of them.
Prepare for the exam in organic chemistry!
