CardioSignal combines smartphone motion sensors and AI to help people detect signs of atrial fibrillation. Accessible heart health checks support earlier medical assessment before complications develop.
CardioSignal asked us to help develop its product and brand for its next stage of growth. The challenge was to convey medical credibility through an experience that felt approachable and human.
With the CardioSignal team and its customers, we developed a vision for the product’s future. The team could work towards it through gradual improvements.
We also helped redesign the brand. The visual direction combined quality and trust with warmth, giving the medical app a more human feel. Product concepts and brand applications showed how this would work in practice.

The team gained a shared product vision to guide development and a clearer visual direction for the brand. These aligned the product experience with how CardioSignal presented itself.
We worked with CardioSignal and its design partners. The original project visuals shown here document that stage of the product and brand’s development.

With the CardioSignal team, Petri Heiskanen, Duotone and Risto Lähdesmäki.
