"Chemical Structural Formula Karuta" incorporates the format of a karuta game, allowing you to naturally acquire knowledge about compounds and chemical structural formulas. It is suitable for a wide range of users, from beginners to those who want to learn chemistry deeply.
"Chemical Structural Formula Karuta" is free. There are no in-app purchases or advertisements, so you can use it with confidence.

■Features of the app
1. Fun learning experience
Chemical Structural Formula Karuta allows even those who are not good at chemistry to learn like a game, so their knowledge of chemistry will become established naturally.

2. Rich card set
Contains a wide range of card sets focusing on the structural formulas of pharmaceuticals, such as hydrocarbons, compounds with functional groups, and compounds with benzene rings, allowing you to visually study while looking at the list.

3. Learning support
Structural Formula Karuta is read aloud, so you can learn chemical structures while listening. You can also watch a video that explains the structural formula in detail. Although it was created with pharmacy students in mind, it is also recommended for high school students in science and engineering departments.

4. CPU battle with multiple difficulty levels
You can change the difficulty level depending on the player's level. It supports a wide range of levels, from solo practice mode for beginners to difficult CPU for advanced users.

■Rules
- Compete for the 25 cards lined up on the table, and the one with the most points wins.
- Three characteristics of the chemical structure to identify the tag will be read out
- Get 1 point if you pick up a card faster than your opponent (you can pick up a card even in the middle of reading)
- If you mess up, you will lose 1 point.
- You can continue picking up bills even if you miss your mark.
- If you make a move more than 3 times, you will lose.

■Target users
- Students: Ideal for preparing for and reviewing chemistry and pharmacy classes.
- Teachers: Can be used as teaching materials and incorporated as part of lessons.
- Chemistry enthusiasts: Recommended for those who want to deepen their knowledge of chemistry.

■Requests for using the app

■Message
Structural Formula Karuta was originally created in a karuta format so that both those who were good at organic chemistry and those who were not good at it could enjoy learning. During the karuta production process, we also received advice from Professor Seiji Esaki of the Faculty of Pharmaceutical Sciences, Osaka Otani University. The production of this app is part of educational research and was supported by JSPS Grant-in-Aid for Scientific Research 23K02725.
I hope that through Structural Formula Karuta, many people will become familiar with chemical structural formulas and will be able to connect this to their next studies.
