The best apps to learn flags, compared
For quick, free flag quizzes, use Seterra. To remember every flag for the long term, use a spaced repetition app: Anki with the Ultimate Geography deck works today, and Bertopia does the same with a friendlier layer when it launches. Flagademy is the best pick for lookalike flags.
How we compared them
We looked at price, how each app decides what you see next, and whether it explains the flags. Quiz apps test you on random flags. Spaced repetition apps show each flag again just before you forget it, so it sticks. Every claim below links to the store page or project page we checked in November 2026. Bertopia is our app, so read its row with that in mind.
The apps side by side
| App | Price | Good at | Weak at | Sources |
|---|---|---|---|---|
| Seterra Geography | Free app, no ads or in-app purchases. The website is free with ads; a GeoGuessr membership removes them | More than 400 quizzes, flags by region, map quizzes on the same app, works offline | Timed quizzes, not a schedule. Nothing tells you which flags to repeat or when | App Store, Google Play, GeoGuessr support |
| Flags of All World Countries | Free with in-app purchases | 197 countries and 48 territories, flashcards to browse, spelling and matching modes, 32 languages | Quiz levels, not spaced repetition. Few explanations of why a flag looks the way it does | Google Play, App Store |
| Flagademy | Free | A similar flags view that groups lookalikes, a mode where you draw the flag, browser games too | New, with few ratings yet. iPhone only on iOS | App Store, Google Play |
| Anki with Ultimate Geography | Free deck. Anki is free except AnkiMobile on iOS | Real spaced repetition, 260 flags, a flag similarity field that names the lookalike, open source on GitHub | You set up Anki and filter the deck to flag cards yourself. Plain cards, no rounds or hints | Ultimate Geography on GitHub, AnkiWeb |
| Bertopia | Free, no ads, no purchases. Not released yet | FSRS spaced repetition for all 195 flags, a hint and a sourced fact on every card, timed practice rounds, Anki import and export | Pre-launch, so you can only join the waitlist today. Flag names are in English only. Only the 195 countries, no territories | Flags pack, Anki compatibility |
Which one to pick
Pick Seterra for a free warm up before a geography class or a GeoGuessr round. Pick Flags of All World Countries for territories and for learning in a language other than English. Pick Flagademy to drill the flags people mix up. Pick Anki with Ultimate Geography if you already use Anki and want flags for good. Join the Bertopia waitlist if you want spaced repetition without the setup, with a fact on every card. When Bertopia launches, it will also open the Ultimate Geography deck, because it reads Anki files.
Flags that every app makes hard
Some pairs are almost identical, and no app fixes that on its own. Our lookalike flag guides show the exact differences, for example Jordan and Palestine or Qatar and Bahrain, with sources for each.
