The ok Khoekhoe app is an excellent vocabulary builder for the Khoekhoe language. It is completely free and offers access to over 1,000 basic Khoekhoe words. The app introduces the user to a new word every day, by default. This feature helps in building vocabulary quickly and efficiently.

The app uses a spaced repetition system (SRS) to optimize memorization and retention of learnt vocabulary. The app tracks the words the user has been exposed to (thereafter 'ok'ed) and quizzes them using SRS. The SRS system has been scientifically proven to be an effective method for learning and retaining new vocabulary. Additionally, the app functions as a simple and straightforward reference Khoekhoe dictionary with an inbuilt search function.
