The Sundanese-English Android dictionary is a bilingual dictionary based on Sundanese and English vocabulary. This Android dictionary uses a layout design that reflects the cultural characteristics of the Baduy tribe. Starting from the dark blue or navy background to the logo image of a typical Baduy stilt house, it will give the impression of regional cultural nuances. This Android dictionary provides a thousand types of Sundanese and English words in its application database. Designed simply, this Android dictionary has three main menus, namely about the dictionary, the dictionary designer team, and Android dictionary features. The aim of developing the Sundanese-English Android dictionary is as a means of preserving regional languages, especially Sundanese-Baduy which is increasingly rarely used by the wider community.
