Appfar - App Design and Development
Behind Appfar is designer and developer Bo Kalvslund. I publish apps for iOS and Android, with over 70 apps and 500,000+ downloads across the App Store and Play Store.
My Approach User experience is at the heart of everything I create. I prototype UI and UX designs in Figma and Affinity before moving to implementation, ensuring that the final product delivers an intuitive and engaging experience.
Professional Background I have over 12 years of experience in app design and development. I’ve worked as an Interactive Play Designer at LEGO, where I contributed to the LEGO Super Mario project—bridging physical and digital play through interactive technology. I’ve also taught app development and Computer Science at high school level for 5 years, helping students learn block programming with App Inventor and Scratch.
Technical Skills I develop apps in Xcode and Android Studio using Swift, SwiftUI, Objective-C, and Kotlin. I’m a power user of Affinity Designer and Photo (as well as the Adobe Suite), with extensive knowledge of illustration, design, and layout. For game development, I work with Unity and C#.
