Map-Quiz is an educational app designed for iPhone users to learn and test their knowledge of countries, states, territories, counties, and boroughs. Developed by Phosphorous Labs Pty Ltd, this free app offers a comprehensive learning experience with over 200 countries, all states and territories of the US, counties of the UK, and boroughs of London.

The app provides two main modes: Practice mode and Challenge mode. In Practice mode, users can take their time and make as many attempts as they need to learn the maps. This mode allows users to thoroughly familiarize themselves with the geography of various regions.

For a more competitive experience, Challenge mode is available. In this mode, users are timed and only three incorrect guesses are allowed. This mode tests users' knowledge and ability to quickly identify the correct locations.

Map-Quiz also features a Top Scores page, where users can see their best timed scores for each map and compare them with other players from around the world. This adds a competitive element to the learning process and motivates users to improve their geography skills.

With its user-friendly interface and comprehensive content, Map-Quiz is an excellent tool for anyone looking to enhance their geographical knowledge. Whether you're a student, a traveler, or simply interested in geography, this app provides an engaging and informative learning experience.
