DNA Call mobile application re-design
The Project
DNA Call is a mobile application for corporate clients, forming a key part of the DNA Vaihdepalvelu (Call Redirect Services). The objective of the project was to completely rewrite the legacy application for native mobile platforms (iOS & Android). Alongside the technical rebuild, the goal was to seamlessly align the application with the renewed DNA brand guidelines, introduce new features, and deliver a modern, highly intuitive tool for business users.
My Role
I joined the product development team as the Lead UI/UX Designer in charge of the mobile application’s visual and interaction design. I worked closely with the development team from the initial native rewrite into a successful launch, followed by continuous, iterative improvements.
- Native App UX & UI Design: I took ownership of the interface design for both iOS and Android platforms, ensuring that native design patterns were respected while creating a unified experience across devices.
- Visual Redesign & Brand Enrichment: I modernized the application’s visual style, refreshing the old interface to better leverage the DNA brand identity. To elevate the user experience, I enriched the UI with brand photography and new visual identity elements.
- Feature & Flow Design: I mapped out user journeys, interaction models, and detailed user flows for the new business features introduced in the release, keeping the core experience simple and distraction-free.
- Design Documentation: I created clean, lightweight visual guidelines and UI documentation for the application to ensure smooth handovers to the development team and maintain consistency in future updates.
Why It Matters
For business users, communication tools directly impact daily productivity and accessibility. Redesigning a technical utility tool into an easy-to-use native application transforms how companies manage their communication workflows. By combining DNA’s brand aesthetics with structured interaction design, we turned a back-office utility into an engaging everyday tool. This ensures employees can optimize their time, respond efficiently, and keep business communications running smoothly.
