Beginner Cajun French is a free mobile application developed by shotgun.experiments that aims to teach Cajun French language to beginners and enthusiasts. The app follows the concept of "a word a day" and provides up to 12 words per day of the user's choosing. Once a user learns a word, the app tests them repeatedly on a decreasing regularity basis. If the user answers the question correctly, the app adjusts the frequency of testing to increase the familiarity of the word. However, if the user answers the question incorrectly, the app will test the user more frequently on that word or deactivate it while teaching other words.

The app offers almost a thousand common and popular Cajun French words to learn, and users can pace themselves to learn the language in a matter of weeks. The app's user interface is simple and straightforward, and it is easy to navigate. This app is an ideal starting point for beginners and language enthusiasts who want to learn Cajun French vocabulary in an engaging and interactive way.
