About Chemical structure Karuta
Chemical structure formula Karuta
Chemical structure formula Karuta allows you to naturally acquire knowledge about chemical compounds and structures through the traditional Japanese card game format ("Karuta"). It is suitable for a wide range of users, from beginners to those who wish to deepen their understanding of chemistry.
This app is completely free. There are no in-app purchases or advertisements, so you can use it with peace of mind.
App Features:
1. A Fun Learning Experience
Even if you find chemistry challenging, this game-based approach helps you retain knowledge naturally while having fun.
2. Extensive Card Sets
The app includes a diverse range of card sets focusing on pharmaceutical structures, including hydrocarbons, functional groups, and benzene rings. You can also study visually using the list view.
3. Comprehensive Learning Support
The app features audio narration, allowing you to learn chemical structures by ear. Additionally, you can view detailed explanatory videos for each structure. While designed with pharmacy students in mind, it is also highly recommended for science, engineering, and high school students.
4. CPU Battles with Multiple Difficulty Levels
Adjust the difficulty to match your skill level. The app offers a wide range of levels, from easy CPU opponents for beginners to challenging ones for advanced players.

- You can take a card even while a hint is being read.
- Making 3 or more mistakes results in a game over.
- You may continue to try for the correct card even after making a mistake.
Target Users:
- Students: Ideal for previewing or reviewing chemistry and pharmacology coursework.
- Teachers: Can be utilized as a teaching tool or integrated into classroom activities.
- Chemistry Enthusiasts: Perfect for anyone looking to deepen their chemical knowledge.
Request for Users:
Upon launching the app for the first time, we kindly ask for your cooperation in completing a brief survey (4 questions, approximately 1 minute).
Note: Survey results may be used for academic research papers.
Message:
This "Structure Karuta" began as a project to help everyone—whether they excel at organic chemistry or struggle with it—enjoy the learning process. During development, we received valuable advice from Professor Seiji Esaki of the School of Pharmacy at Osaka Ohtani University. This app is part of an educational research project and is supported by JSPS KAKENHI Grant Number 23K02725.
