Enhancing a Personalised Physical Activity Platform with Behaviour Change Design
We partnered with a medical-grade physical activity platform to strengthen the behavioural foundations of their app and improve the user experience for people receiving personalised activity prescriptions. EXI, a CE and UKCA-marked Class I medical device, approached us to enhance the platform from both a behaviour change and user-centred perspective.
The Challenge
The organisation wanted to improve how their app supported people to build sustainable physical activity habits. They recognised that while the medical and algorithmic elements of the platform were strong, there were opportunities to deepen the behavioural-science structure, enhance engagement, and ensure the experience better aligned with the needs of users and healthcare professionals.
Our Approach
We conducted a behavioural audit of the app and its wider ecosystem, examining motivation, capability and opportunity barriers through the COM-B model. This included co-design sessions with healthcare professionals, analysis of key user groups, and a review of communication pathways and habit-building components. We focused on identifying where engagement could be strengthened and how user journeys could be made clearer and more supportive.
Solution Delivered
Our work resulted in targeted recommendations to optimise behavioural pathways, refine user journeys and strengthen the app’s habit-formation features. We identified opportunities to embed evidence-based techniques more consistently, ensured behaviour change components aligned with users’ lived experiences and preferences, and translated insights into practical changes using agile design tools. The organisation received guidance on how to enhance both the app interface and the supporting digital content to create a more user-centred, motivating experience.
Impact
The project improved the organisation’s capability to deliver behaviourally informed digital health solutions. By strengthening engagement mechanisms and embedding clearer behaviour change techniques across the app and communication channels, the platform now offers a more supportive and personalised activity experience. These enhancements contribute to better adherence, stronger user motivation and a more cohesive behaviour change ecosystem.
