Questionmark is a free app that helps you make sustainable and healthy choices while shopping. Developed by Stichting Questionmark, the app provides information on the sustainability themes of environment, human rights, and animal welfare, as well as assesses whether the product fits within a healthy diet. With over 50,000 products from all major supermarkets, the app is a must-have for conscious shoppers.

Using the app is easy. You can either scan the barcode on the product packaging or search for the product. The app then displays the health and sustainability information, making it easy for you to make informed choices. If necessary, you can also choose an alternative product.

The app provides a wealth of benefits, including understandable product information, all ingredients and nutritional values in one place, and an integrated search function. It is based on internationally and scientifically accepted standards, and the foundation aims to realize a more sustainable and healthier food system.

Questionmark is an independent foundation that is transparent and free to use. It is a valuable tool for anyone who wants to shop sustainably and healthily.
