◆ Remember with Mnemonics, Never Forget Again

All 327 questions come standard with mnemonics.

For example—
• "An impressive (Yin-Shang) hero (1600 BC)! Appears on the Yellow River!"
• "A new graduate's (new employee's) monthly salary was 200,000 yen (200,000 years ago)"
• "All my relatives (Neolithic)! Let's call a truce (9,000 years ago) and start farming!"

Numbers and events are connected in a humorous sentence. Quick and memorable. This is the memorization experience of this app. You can also overwrite and save mnemonics you don't like with your own.

◆ SM-2 Spatial Repetition (Spaced Repetition Learning)

Another feature of this app is its review scheduling based on the scientifically proven SM-2 algorithm.

• Correctly answered questions are reviewed at gradually longer intervals, efficiently transferring them to long-term memory.

• Incorrectly answered questions are re-presented at shorter intervals, focusing on reinforcing weak points.

• Review notifications are provided at the optimal timing, tailored to each individual's proficiency level.

The app automatically manages "when and what to review," so all you have to do is open the app daily and answer the questions presented. Even with a substantial volume of 327 questions, you can learn efficiently without wasting time.

◆ Intellectual Design Inspired by the Sky and Earth

As an app for learning world history, the design also reflects the vastness of the world.

* A light sky blue to cyan color scheme inspired by the dawn sky (Light Mode)
* A deep navy to deep blue tone inspired by the Earth at midnight (Dark Mode)
* A modern card design with a frosted glass effect (Glass Morphism)
