Beginner Croatian is an Android app designed to introduce beginners and enthusiasts to the Croatian language. The app follows the "a word a day" concept and offers up to 12 words per day for users to choose from.

The app uses a spaced repetition system to help users learn and remember the words. Words that are answered correctly are tested less frequently, while those that are answered incorrectly are tested more often until the user gains familiarity with them. The app also deactivates words that are consistently answered incorrectly, allowing users to focus on learning other words in the meantime.

With almost a thousand common and popular Croatian words available in the app, users can pace themselves and learn at their own speed. In just a few weeks, users can have a solid understanding of the Croatian vocabulary. Overall, Beginner Croatian is a simple and direct app that can help users get started with learning the Croatian language.
