Ka Piki is an educational app designed for iPhone users aiming to boost their vocabulary and understanding of te reo Māori. The application employs the "input hypothesis" of language acquisition, exposing learners to a large volume of words and phrases at a rapid pace. This immersive approach helps users learn through repeated exposure and comprehension.

The app addresses common challenges in learning sentence structure and grammar by displaying sentences with visual aids. These aids reinforce correct word order, enhancing overall understanding. Developed in Wellington by a dedicated team, Ka Piki is committed to improving its learning content, promising users more lessons and resources in future updates.
