World Flags Trainer

World Flags Trainer uses adaptive spaced repetition and active recall to help you master every national flag. It combines two practice modes—Multiple Choice for quick familiarity and Self-Assessment for focused recall—with an adaptive algorithm that schedules reviews at optimal times, ensuring steady progress without frustration. Flags are grouped by continent and practiced in two directions: Flag to Country and Country to Flag.

During sessions, items repeat until you’ve answered them correctly at least once, and incorrect answers adjust the interval rather than resetting progress. Knowledge tests with medals provide an accurate read of your current skill, and you can earn silver or gold medals in each category and direction. Categories and questions can be adjusted freely, and you can browse or search all flashcards for quick reference, creating a concise, sustainable path to mastery.
