In 2014 Julia Korbut created a design concept for K-9 Mail using Material Design.

Since then we’re determined to modernize and optimize both the user interface and the user experience. In order to approach this task in a systematic way Julia created a short user survey to gather feedback from you, the users of the app.
Please help us by participating. It shouldn’t take longer than 3-5 minutes to complete.
