wheretobio is an application which was available on iOS and Android, allowing users to easily find local farmers market near them. First version was release in February 2020.

As the first free community platform, Wheretobio locates 200 local direct sales outlets. It brings together farm markets, self-services and vending machines, and continues to grow thanks to new addresses shared by consumers. People wishing to eat locally can easily find a wide choice of products listed in eleven categories, ranging from fruit and vegetables to Christmas trees.


Wheretobio is a community of producers and consumers with more than 1000 active members. It offers a very complete directory since the interactive map now lists more than 200 local addresses. There are details of the assortment, opening hours, as well as useful links pointing to the website and their social networks. With 11 categories, ranging from fruits and vegetables to Christmas trees, the user easily finds what he needs in the perimeter where he is located. Whether using the filter on the map or doing a text search, consuming local has never been easier. Everyone can continue to add new addresses and thus make their favorite tips more widely known. The directory is constantly updated. Small producers thus have as much visibility as many other businesses. The application is completely free, both for producers and consumers, and without advertising. Romand for the moment, the directory – which exists in four languages ​​– aims to develop throughout Switzerland.
