Capitals of the World Pro
A refined geography training app for learning world capitals through fast recall, flag prompts, weak-spot review, flashcards, and local progress tracking.
Capitals of the World Pro turns a world-capitals study tool into a complete local-first web app. It combines a structured geography dataset, local flag assets, flexible quiz directions, smart answer checking, progress tracking, and seven focused study modes inside a responsive interface designed for repeated practice.
The app runs as a static HTML, CSS, and JavaScript project with no backend, no build step, and no account system. Progress lives in the browser, flags ship as local PNG assets, and the entire study workflow is built for a polished daily-use feel rather than a one-off quiz form.
Seven study modes
Classic Type, Multiple Choice, Flag Challenge, Weak Spots, Timed Sprint, Flashcards, and a searchable Review Table.
Flexible practice controls
Practice by region or the full world, switch direction, choose 60 / 90 / 120-second sprints, toggle flags, auto-advance, and strict mode.
Smart answer checking
Normalizes casing, accents, punctuation, separators, and whitespace, with stricter validation available when needed.
Local flags & visual memory
Ships with 270 local PNG flag assets used as prompts, visual support during practice, or hint reveals.
Progress & mastery
Tracks correct, wrong, assisted answers, streaks, best streaks, recent results, and per-item mastery, all stored locally.
Hints & review tools
First-letter, answer-length, and flag hints, plus progress export, import, and local reset for portable study data.
Open the app
Capitals of the World Pro opens in any modern browser as a static site, no install, no account, no setup. The dataset, flag images, and quiz logic load locally.
Pick a mode and group
Choose one of seven study modes and a practice group, All (World), Africa, Asia, Europe, the Americas, Caribbean, Oceania, or Territories / Other, then start answering.
Track progress locally
Every answer updates streaks, accuracy, and per-item mastery in browser storage. Weak Spots mode then prioritises the items you keep missing.
- 249 world entries across 10 practice groups, including a dedicated Territories / Other group with 54 records.
- 270 local PNG flag assets bundled with the app, no remote image service required.
- Accent-, casing-, and punctuation-tolerant answer matching, with an optional strict mode for tighter validation.
- Multi-capital cases handled cleanly, with the review table aligned to the active quiz data.
- Local-first progress model with export, import, and reset, so progress is portable without an account.
- Responsive interface with a left navigation rail, centered quiz stage, progress cards, hint tools, and dark/light theme support.
Product-grade frontend without a framework
A polished, responsive study workspace built with vanilla HTML, CSS, and JavaScript, no framework, no build pipeline, no runtime dependencies.
Local-first data design
Geography data, flag assets, and learner progress all live on the client. The app is fully usable offline and never depends on a remote service for its core loop.
Considered learning UX
Seven study modes, flexible directions, weak-spot targeting, flashcards, and a searchable review table turn the same dataset into several genuinely different ways to study.
Careful data modelling
Aliases, alternate spellings, accented variants, and multi-capital cases are handled in the dataset rather than papered over in the UI.
Pricing
One simple price for the full Capitals of the World Pro web app, ready to use in a modern browser.
