Wellune proposes a way for users to get a comfortable and healthy sleep by analyzing sleep data such as sleep patterns and sleep environments by linked sensors. The Grap successfully renewed the app service design of Wellune and added a B2B version of Wellune for Business based on a high understanding of the service. Consistent and state-aware UI and graphic images were applied to enable a large number of unspecified sleep managers to monitor the manager screen efficiently, maintain the identity of the app, and implement a simple but trendy design.
