PALAVA is an Android app developed by Landschaftsverband Westfalen-Lippe, available for free in the Education & Reference category. The app aims to gather insights into how people in North Rhine-Westphalia (NRW) speak in their daily lives, showcasing the diverse linguistic variations within the region.

Users can participate in engaging questionnaires about their everyday language habits, exploring differences in dialects across NRW. The app features interactive question rounds where users can record their responses anonymously, followed by fun tasks testing their knowledge of regional expressions and sayings.

PALAVA also allows users to listen to the spoken answers of other participants regarding various topics, providing a platform to compare and learn about different linguistic preferences. Additionally, users can access analyzed language maps and statistics under the "Results" section, contributing their voice recordings for ongoing scientific research on NRW dialects. PALAVA encourages active participation in uncovering and celebrating the linguistic richness of NRW.
