Out with the old, in with the new

The former Denner app was developed in 2012 and was accordingly no longer up to date, both technically and visually. It was time for a modernization!

The new app has been implemented natively for the most part. Content is loaded in the background, which prevents long loading times.

The wine shop is integrated as a webview. Mid-term, this will remain the same: As is often the case, there are dependencies on many peripheral systems, which can quickly become relatively complex, especially when it comes to online shops. This raises the question of whether a native implementation makes sense in the given and grown system landscape. In the case of the wine shop, the Denner and Apps with love project teams decided to wait with a native implementation until the systems in the background had been modernised and simplified, so that a native implementation would be easier to realise. Apart from that, the current solution works and the users are familiar with it - don't fix what ain't broken.

Convenient shopping at Denner 

The new app is designed to bring even more benefits to Denner customers, which is why existing functionalities have been improved and new functionalities added:

Improved overview of promotions: Products are displayed more clearly and the filter function has been improved. Promotions can now be searched easily.

Shopping lists: The shopping list feature has been greatly improved and made more accessible. Lists can be shared, edited together and supplemented with individual notes, products can be added to the desired shopping list with one click.

Personalize: The app can be set up according to your own preferences so that only promotions that really interest you are displayed. For example, non-smokers can disable the promotions on tobacco products. The same applies to alcohol consumption, meat consumption or lactose intolerance. You can also set up notifications according to your own preferences.

Login: The implementation of the Migros login allows the synchronizing of settings or, for example, the shopping list between devices. It also creates a link to denner.ch and the wine shop.

Promotion alerts: In order to never miss a promotion, practical promotion alerts can be set up. Users are notified as soon as the desired product is on sale.

Improved store locator: The revised store locator shows the shortest route to the nearest Denner store and provides information about current opening hours and local offers. The regular store can be added as a favourite.

The design was modernized, especially the presentation of promotions was made clearer. However, clear identification marks such as the Denner price tag and the visual language remained in focus.

UX writing - clear, concise and helpful texts

A good user experience includes not only a beautiful design and an easy-to-use interface, but also clear and easy-to-understand texts. Users should be guided through the interface as intuitively as possible, and interaction with the app should feel natural. This is where UX writing comes in. The individual short text modules, the so-called microcopy, are analysed and improved.

Specifically this involves buttons, titles, error messages, call-to-actions, empty states and so on.

During the design process, we scrutinized these text modules in the Denner app with the support of Jrene Rolli. We added or simplified unclear phrases and standardized the tone of voice so that it matched the rest of Denner's communication style. The texts were then translated and optimized again by a French- and an Italian-speaking UX writer.

User-centred approach

Major innovations are not always well received by users. It is therefore all the more important to listen to the feedback of the community and to take their input into account in new and further developments. For example, shortly after the first release, the shopping list feature was adapted again to better meet the wishes and needs of the users.
