!Flags - Learn world flags fast. Quiz + achievements on iOS.

I built !Flags after a paper card game with my son. We were guessing flags at the kitchen table when he said, “Dad, make this on the phone.” So I did. The goal: a calm, ad-free way to learn world flags in minutes a day. What’s unique here: • Bite-size quizzes that take 30–60 seconds • Achievements and progress by continent to keep momentum • “I’ve been here” tracking to mark visited countries • Five languages: EN, UA, PL, ES, DE • iOS only, free to start, one-time PRO, no ads, works offline Proud of the little things: smooth haptics, clear typography, and a learning loop that’s friendly for kids and still fun for adults. It’s our small father-and-son project that grew into a polished app. I’d love your feedback: which mode should we build next (speed run, capitals pack, hard mode without hints)? Thanks for checking it out and for any upvotes, comments, or bug reports.
