Are you interested in using an app to help you buy healthier foods when shopping?

The SwapSHOP Study

Swapshop logo

Oxford University researchers have developed a smartphone app that can help shoppers to buy healthier foods at the supermarket. This app will allow you to scan food product barcodes across leading UK supermarkets to track your food purchases.

In this study, we want to test if this app works as intended and if you found it easy to use and helpful to support you to make changes to the foods you buy.

The study will take 6 weeks and will involve you scanning the supermarket foods you buy.

You will be reimbursed for your time.
