App redesign for the first German online canteen


Smunch is b2b business, a food/tech German Startup with its headquarters in Berlin. They have an important mission to provide tasty lunches to hungry employees - directly to their workplaces. 

The redesign of the App followed because Smunch wanted to create a user-centered digital product that could match the users’ needs and provide a great overall experience - from ordering the food to receiving it.

Different issues as holes in the general user flow and UI lead to shortcomings and dissatisfaction with user expectations. Therefore, there were lower conversion rates, no matter the number of monthly on-boarded new users.

User test, surveys, workshops

Workshops – We ran stakeholder interviews and gathered all company departments in order to identify what problems they were facing as well as what should be improved.

Testing the old platform – There were also tests with the old platform and actual users. We equipped ourselves with extra food vouchers and a good mood as went out to meet the real customers. We aimed to have user testing sessions with all types of user personas. We ran both live interview sessions with users and also sent out questionnaires. In order to identify the real user needs, what they liked and what they didn’t like, we carefully prepared the scenarios, questions, and hypothesises which we needed to test and validate.

Design Sprints

We followed a weekly sprint schedule for five weeks until we were satisfied with the results and we saw the overall refinement. As a result, there was a huge improvement in the way users were interacting with the product and the prototypes. During the user testing sessions, we were constantly reviewing our user goals. We also allowed the natural way the users were using the product to guide us. This phase helped considerably in building a new logical, easy to use navigation system and sitemap.

Wireframes and Prototypes

During the first weeks and testing sessions, we already created some wireframes and lo-fi prototypes. However, these really needed to be polished and finalized. In order to set the stable base for the next phase, we completed all of the wireframes, new components and elements for all devices with an explanation of how they work.

Polishing the designs and sitemaps

As we wanted to have a really clear picture of how the new app should function, we designed new sitemaps for all devices and revisited the user flows. We then went through most of the user cases in order to improve them.

Design System

Keep it simple - that was the main thing we wanted our design system to be. Everything started by sketching and laying down the first elements, components, modules, and styles. There was a simple design system with all basic elements we needed to start designing the app screens. It later turned out that this method worked particularly well as we maintained simplicity and consistency within the app. 

See some examples of the design system elements bellow.



Input fields and notification


Visual Assets

Improved visual factors. An example of this was, adding more appealing food-inspired colour tones and creating a shades palette, which consisted of all of the main colours. Not only was the colour improved, completely new graphic and motion elements were also designed. These consisted of   system icons, illustrations, micro animations, and animations. All of these new assets were made in order to serve the app functions. For example, giving feedback to the user, improving accessibility, and creating enough contrast.






Animations and Micro animations

Animation – New appealing login screen designs. We completely updated the log in screen design and user flow in case the user forgets their password or if they need further help. From a UI perspective, we decided to create a welcoming animation as the log in screen is first thing the user sees. We wanted to welcome them and also show the friendly character of the brand.


Mobile interactions

Improved visual factors. An example of this was, adding more appealing food-inspired colour tones and creating a shades palette, which consisted of all of the main colours. Not only was the colour improved-, 


What’s new?

New top and bottom navigations. The app navigation system was improved and not only in the way it looks, but also in organizing the most useful information by making it more visible when needed. For example “ratings” or “filter” are considerably important. They appear on the bottom navigation of the dashboard, where the user can easily apply them.


Adding character to the app

Adding more visual character to the app through creating graphic elements, illustration, patterns, micro animations and using the new colour palette.

We gave the Smunch app a unique character and brought in to life. The improved content and tone of voice also made a difference.


New dashboard design and a new helpful navigation feature

All dashboard screens were also completely redesigned with a focus on mobile devices. The order process is particularly easy. The preferred dish is ordered with one only click as the status of the dish card is changed to “ordered”.

Day filter feature - We added a calendar below the top navigation which enables users to easily navigate through the available days for ordering. This new feature also makes it easier for users to make decisions by neatly organizing the interface. This allows it to be more easily understood by new users. There is also a new and improved quick view with detailed meal information for the users who need more information to make a choice.



Even with the time constraints we had, we managed to go through all of the planned steps.

We found that when there is such a big project as the one we did, it’s especially important to spend enough time on setting the right goals and do regular planning and revisions. Spending a bit more time on user testing sessions, interviews and workshops pay off later. And one more important thing to mention — it is not the end. It is a stable base for future improvements and changes.
