ALEXANDER KÄẞNER

Digital Product Designer (B.A.)

Berlin, Germany

Hi! I’m Alex — the designer you need for all kinds of digital products like apps, websites, icons and much more.

Over the last 10+ years, I’ve worked on several projects with different clients, built and shipped my own products, co-founded an app company, and helped shape the future of design tools at Sketch. In 2020 I completed my Bachelor’s Degree in Interface Design at the UAS Potsdam.

Currently, I work as a UI/UX designer at Datawrapper.

MeterStats for iOS

For my newest app, I’ve designed and developed the ultimate tracker to monitor energy, heating, and water usage. MeterStats is designed to enable people to analyze their consumption and test how specific events affect energy usage. It’s built entirely with SwiftUI and utilizes Apple’s latest Swift Charts framework for the detailed charts.

Diagrams for Mac

Over a period of four years I helped design and successfully ship Diagrams — first as a freelancer, later as a co-founder. My role was everything design, including the app icon, UI, website, marketing, product videos and many other startup-related tasks.

iPad Main Menu Concept

For my bachelor’s thesis I worked out a concept of how a main menu we know from desktop computers could work on a touch device like the iPad. The main menu could be the foundation for more advanced pro apps on tablets by providing a place for more elaborate feature sets.
