草花の名前を覚える is an app designed to help users memorize the names of various flowers. The app allows users to differentiate between flowers they already know and those they are unfamiliar with. Unfamiliar flowers are presented as questions until they are memorized.

To reinforce memory retention, questions are presented just before the user forgets the answer, allowing for repeated recall and solidification of memory. When the achievement rate reaches 100%, it means that all the flowers have been memorized. However, over time, the user may start to forget, causing the achievement rate to decrease.

By answering "I know" to the first question, the user won't be asked about that specific flower for three months. By answering "I don't know," the user will be asked the question again a few minutes later. Answering "I know" to subsequent questions will result in the question being asked again after one hour, then 24 hours, and so on, with increasing intervals.

The app also offers the option to start from the beginning if the user answers "I don't know" at any point. Through this process, users will gradually solidify their memory without even realizing it.
