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 worked on several projects with different clients, built and shipped my own products, co-founded an app company, and helped bring the productivity app Diagrams to the market. In 2020 I completed my Bachelor’s Degree in Interface Design at the UAS Potsdam.

More recently, I worked as a Product Designer at Sketch.

Recent Work

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.

Sketch

I joined the great people of Sketch — the app that changed the design tools landscape forever — as a Product Designer. Being part of the Collaboration Team, I worked on features like live collaboration, document sharing, versioning, web canvas and commenting.

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.

Keepfully for iOS

I designed and developed this app myself as part of the pxlwaves lab app catalog. Keepfully helps you to keep track of money you borrow from friends, family or colleagues. The iPhone and Apple Watch app is designed for fast input and quick overview of your loans.
