Flag Quiz: Europe & World is a free flag quiz app for Android and iPhone that drills all 254 national and territorial flags offline, in seven modes, using spaced repetition. There are no ads, no subscription and no account, and 35 curated groups of lookalike flags target the pairs people genuinely confuse.
Disclosure: AppStoryo is operated by the studio that develops Flag Quiz: Europe & World. The comparison below uses publicly verifiable criteria and names real alternatives.
What does Flag Quiz: Europe & World actually do?
Flag Quiz: Europe & World is built around seven modes rather than one. Learn schedules each flag with spaced repetition and tracks mastery from 0 to 100 per cent. Classic Quiz gives four options in either direction. Similar Flags draws its answer options only from inside one of 35 curated lookalike groups. Type It accepts tolerant spelling, Time Attack runs 60 seconds with a combo multiplier, and Capitals goes from flag or country to capital and back. Encyclopedia browses, searches and filters all 254 entries.
The iPhone download is 47.4 MB and needs iOS 13.0 or later across 130 supported devices. One wrinkle matters before you search: the app ships under two different store names. On Google Play it is Flag Quiz: Europe & World; on the App Store the same app is listed as All Country Flags: Learn 254. The Play listing went live on 6 October 2026, and the iPhone version has been available since 13 August 2026.
The Play listing's own What's new entry states the pitch plainly:
All 254 flags of countries and territories. 7 modes, including Similar Flags, Time Attack and Capitals. Spaced repetition shows each flag right before you would forget it. 100% offline. No ads, no subscriptions, no account.
How many flags are there to learn, and is 254 the right number?
There is no single answer, which is why flag apps disagree. The United Nations counts 193 Member States, up from 51 in 1945. Unicode's published emoji sequence file lists 259 recommended flag sequences for regions, plus three tag sequences for England, Scotland and Wales. IANA's root zone database holds 316 country-code top-level domains.
So 254 sits deliberately between those numbers: well above the roster of sovereign states, below every code point anyone has ever assigned. The practical effect shows up in a comparison. Flags of the countries - Quiz says in its own description that it covers 199 countries, so the 55 extra entries in Flag Quiz: Europe & World are mostly the dependent territories that a pub quiz or a geography exam will still ask about.
Does spaced repetition really make flags stick?
The evidence for the underlying method is strong and it is not app marketing. A review in the Yale Journal of Biology and Medicine sets out the testing effect, active recall and spaced repetition, and cites an experiment on learning names at a party: the group that practised retrieval recalled 11.5 names on average, against 5.8 for the group that simply saw the names again.
Flags are the same shape of problem as names, which is why the Learn mode is the part worth using. You self-grade each flag, the schedule pushes your weak ones forward, and a per-flag mastery percentage plus a world heat map show where the gaps are instead of leaving you to guess. If that is the way you want to study, install Flag Quiz: Europe & World on Google Play.
What happens to your data if the app never goes online?
The Google Play Data safety panel for the app declares no data collected and no data shared with third parties, and the App Store description says there is no analytics, no advertising, no crash reporting and no identifiers. Progress stays on the device.
Treat those panels as what they are. Google's own developer help page on data disclosures states that the developer supplies that information and may update it over time, so a declaration is a published commitment rather than an audit. The checkable part is behaviour: an app with nothing to upload and no account to sign into has nowhere to send a score.
Which flag quiz app should you actually use?
Choose Seterra Geography (full) if you want maps more than flags
- Free with no ads or in-app purchases, by its own description, and 16,728 App Store ratings at 4.8 behind it.
- More than 300 games, most of them about pinpointing places rather than naming flags.
- The trade is bulk and reach: 186.2 MB, iOS 15.1 or later, and an App Store listing in English only.
Choose Flags of the countries - Quiz if you want the smallest, oldest flags-only app
- 10.8 MB, iOS 13.0 or later, on the App Store since August 2018 with 2,185 ratings at 4.8.
- 13 interface languages, against English only on the App Store listing for Flag Quiz: Europe & World.
- Its own description claims 199 countries and respects flag proportions, but it advertises no spaced repetition and no mastery tracking.
Choose StudyGe - World Geography Quiz if you want breadth and other players
- 26 interface languages, 5,230 ratings at 4.6, updated 4 October 2026.
- Flags sit alongside capitals, coats of arms, 30-plus indicators per country, historical maps and multiplayer matches.
- That breadth costs 211.5 MB and, for the multiplayer part, a connection.
Choose Flag Quiz: Europe & World if you want all 254 flags drilled offline
- 254 entries against the 199 its closest flags-only rival advertises, and 35 hand-curated lookalike groups.
- Spaced repetition and per-flag mastery, rather than score-chasing alone.
- 47.4 MB, iOS 13.0 or later, no ads, no subscription, no account: get Flag Quiz: Europe & World on Google Play.
When is Flag Quiz: Europe & World not the right app?
Four cases, and they are structural rather than teething problems. If you need to find countries on a map, this is the wrong tool and Seterra Geography (full) is the right one. If you need the interface in your own language, the App Store listing declares English only, where Flags of the countries - Quiz offers 13 languages and StudyGe - World Geography Quiz offers 26.
If you study across a phone and a tablet, there is no sync and no account, so each device keeps its own streak and a lost handset is a lost history. And if you pick apps on social proof, there is none yet: a 0+ install band on Google Play and no user ratings on either store, against 16,728 for Seterra Geography (full).
What else do people ask about Flag Quiz: Europe & World?
Is Flag Quiz: Europe & World free?
Yes. Both store listings show it as free, and the Google Play entry declares no in-app purchases and no ads. There is no subscription tier, no paid unlock and no rewarded video, so all seven modes, all 35 lookalike groups and all 254 flags are available from the first launch.
Does it work without an internet connection?
Yes. Every one of the seven modes runs offline and there is no account to sign into, which is the point of the design. The App Store description goes further and says that on Android the app does not even declare an internet permission, so no score and no streak can leave the device.
How many flags does it include, and which ones?
254 entries: every country plus the dependent territories most quizzes skip. For scale, the UN lists 193 Member States and Unicode publishes 259 recommended region flag sequences, so 254 sits between the political roster and the full technical list of flags that software can draw.
Which flags do people confuse most often?
The app ships 35 hand-curated groups for exactly this problem, and its own listings name three pairs: Chad and Romania, Indonesia and Monaco, Slovenia and Slovakia. In Similar Flags mode the four answer options come only from within one group, so guessing by elimination stops working.
Does it teach capital cities as well?
Yes, in a dedicated Capitals mode that runs in both directions, from a flag or a country name to its capital and back again. If you want capitals bundled with coats of arms, population and economic indicators instead, StudyGe - World Geography Quiz covers considerably more ground.
Is there an iPhone version?
Yes, but it is listed under a different name, so search the App Store for All Country Flags: Learn 254 rather than the Google Play title. It is a 47.4 MB download, needs iOS 13.0 or later, runs on 130 supported devices, and has been available since 13 August 2026.
Can you practise one region, such as Europe, on its own?
Yes. The Play description says you can filter by continent and by difficulty, so a Europe-only flag quiz is a filter rather than a separate mode. You can widen the same filter to the whole world once the European set stops catching you out, without losing your recorded progress.
Does it track which flags you keep getting wrong?
Yes. Each flag carries a mastery figure from 0 to 100 per cent, your weakest flags are surfaced automatically, and a world heat map colours every country by how well you know it. Daily streaks, per-flag statistics and around 30 achievements sit on top of that.
How does it compare with the long-established flag apps?
On coverage it leads: 254 entries against the 199 countries that Flags of the countries - Quiz advertises in its own description. On track record it does not, with no user ratings on either store against 2,185 for that rival and 16,728 for Seterra Geography (full).
