Beginner Indonesian is a free Android app that offers a simple and direct introduction to the Indonesian language. It is designed for beginners and enthusiasts who want to learn the language using the 'a word a day' concept. The app provides up to 12 words a day, which the user can choose.

The app uses a spaced repetition system where all words learnt are repeatedly tested on a decreasing regularity basis. If answered correctly, the app adjusts to test the user less frequently. If answered incorrectly, the app will adjust to test the user more on the word or deactivate it while the user learns other words. With almost a thousand common and popular Indonesian words available, the app helps users pace themselves as they learn. Within a few weeks, users can have an essential knowledge of the Indonesian vocabulary.
