Built-in confusable mode for easily mixed-up flags (e.g., Chad vs Romania, New Zealand vs Australia). SM-2 Spaced Repetition Review Missed flags and aging cards are automatically queued for review.

Fully Offline All data is bundled in the app. Every feature works without Wi-Fi, LTE, or any network connection. ā–  Data Sources Country, capital, and currency data: Wikidata (CC0 license). Flag SVGs: flag-icons (MIT license). ā–  Privacy Your learning data, including your nickname and study records, stays on your device and is never transmitted externally. To keep the app free, FlagDeck shows ads (Google AdMob) and collects screen-usage statistics (Google Analytics for Firebase) to improve the service. See our Privacy Policy at https://legal.therene.co.kr/flagdeck/ ā–  Contact support@therene.co.kr Built by a solo developer who simply wanted to memorize country names and capitals. I hope it helps others with the same goal. Feedback is always welcome.
