Wedding App

Make it perfect


For their marriage in 2018, M. and J. wanted to make this event even more unique thanks to a mobile application.

Initially designed to handle invitations. This application has been improved with the ability to take photos and videos.
These photos were visible on a big screen during the evening.

The application also allows to submit and vote for songs.

Once the wedding was over, the application allowed people to view all the pictures taken and download the ones they wanted.

Light and efficient design

Achieve an intuitive interface while giving a strong seal on the visual level.

Key points

Setting the mood

Since it's a wedding, it seemed important to us to have a strong visual identity. That's why we did an animation at launch featuring the soon to be weds. They descend from a heart-shaped balloon into their car.


When opening invitations, the car drives along the road to reach the church. During the trip, practical informations such as time and address appears on screen.

Managing guests

Important phase before the wedding, the invitations are sometimes a complicated task to manage. Especially since they must be personalized.
Thanks to a simple icon set, our application makes it easy to give groups a particular type of invitation (Church, Meal, Party, .. .)


This admin panel also allows you to see who has already viewed the invitation and who has already responded.
In addition, it is possible to collect valuable information, such as the number of children, if people want to eat vegetarian, want to sleep nearby ...
