The Willys app is designed for Willys customers, offering features such as shopping and viewing offers from Willys and Willys Hemma. Users can access current promotions and personal offers, as well as shop directly through the app at the same low prices as in-store. The convenience extends to choosing between picking up purchases in-store or having them delivered to their homes.

A standout feature of the app is Scan & Go, which simplifies the shopping experience in Willys stores. Customers can self-scan items and make purchases directly through their mobile devices. Additionally, users can create shopping lists by adding offers or other items, with easy access to these lists within the app or when logged in on the website. Sharing lists with household members is also possible.

The app's menu provides a hub for tracking purchases, managing accounts, accessing Willys Plus benefits, store locations, customer service contacts, and savings through Willys Plus. For those not yet Willys Plus members, joining offers enhanced deals and benefits at Willys and Willys Hemma, all for free. By using the Willys app to sign up, users can immediately access exclusive Willys Plus offers without the need for waiting for a physical club card.
