GIOLE is an Android application developed by VĂN PHÒNG HỘI ĐỒNG GIÁM MỤC VIỆT NAM. It is a free travel and navigation app that allows users to search for Sunday Mass and weekday church services in Vietnam. With a database of over 2000 churches in Vietnam, GIOLE provides essential information such as the time of Sunday Mass, address, and map location.

One of the standout features of GIOLE is the ability to search for services based on specific time parameters. Users can easily filter and find the most suitable Mass time within a given day. This feature is particularly helpful for individuals who have time constraints or prefer attending Mass at a specific time.

Another useful feature of GIOLE is the "Nearby Search" function, which enables users to find church services in the vicinity of their current location. This feature comes in handy for travelers who don't want to miss out on attending Mass when visiting different localities.

GIOLE is developed by KNS & ZenS, aiming to bridge the gap between technology and the younger generation's engagement with Mass. In today's modern world, many young people find it challenging to participate in religious activities. GIOLE leverages technology to bring the younger generation closer to the Mass experience.
