About

UN Flagz

Features
Read full description

Flagz is the smartest way to learn the flags of all 193 UN members — through a memory-matching trainer that actually makes it stick. Flip tiles to find matching flag pairs. When you find a match, a quick quiz pops up: can you name the country? Get it right, and that flag moves closer to "learned." Get it wrong, and it comes back around. After 3 correct identifications in a row, a flag is marked as learned and retired from the deck — so you always focus on what you don't know yet. Features: • 193 UN member state flags • Memory-matching trainer with built-in quiz • Smart spaced repetition — learned flags leave the deck • Tap a matched flag for country facts or its location on a map • Progress tracking across sessions • Clean, distraction-free design • Works offline
