WhatsHalal is a free Android application that offers a complete halal food discovery experience. It is an all-in-one platform that provides a directory search of over 5000 halal certified and Muslim-friendly restaurants in various countries such as Singapore, Malaysia, China, Vietnam, Japan, Australia, Indonesia, South Korea, and the USA.

One of the unique features of WhatsHalal is the ability to pre-order from WhatsHalal partners (Singapore only) and collect the food directly from the restaurant. Additionally, users can register for Qurban, Aqiqah, and Nazar services for distribution in Bandung, Indonesia, performed by the app's ethical, free-range farm and abbatoir in Indonesia.

Another useful tool of WhatsHalal is the ability to scan the barcode of products at hypermarkets and check if it's likely halal or not, even if there's no halal certificate. Users can also contribute to building the app's product and ingredients database by taking and uploading photos of products.

Overall, WhatsHalal is a great app for those looking for halal food options, ethical halal agriculture services, and an easy-to-use interface to discover and order food from certified halal restaurants.
