About this app

The Integral Gacha is a service released on the Oishii Mathematics website on May 19, 2021, that randomly presents five integral calculations from Mathematics III of high school mathematics. This app version inherits the functionality of the web version and is an enhanced version.

The app version has the following features in addition to the web version:

1. More questions than the web version, with a current total of 134,664,255 possible gacha combinations (compared to 20,700,900 in the web version).
2. Unlimited gacha spins, no time limit.
3. Advanced-only switch (press (5) to ensure an advanced level is drawn).
4. Additional information included (contains relevant information such as background knowledge and sources for the questions).
5. Built-in timer (measures up to 100 minutes after spinning the gacha, useful for time attack).
6. New question identification function (distinguishes between new and previously asked questions).
7. Marking function (allows you to mark questions you answered correctly).
8. No ads.
9. List of all problems from beginner to advanced (including problems added to the web version)
10. Link to the page for Oishii Mathematics Integration, which has been improved for the app (even those who have not yet studied Integration in Mathematics III can start from scratch)
11. Calculation sheet function (simple)
