Unlocking Health Potential: Insights from Holly Health Primary Care Users

July 27, 2025

Background and Use Case

Holly Health is a digital health platform supporting individuals in improving their health and wellbeing. It supports sustainable lifestyle habit changes through personalised app-based coaching, goal setting, nudges & boosts, tracking, interactive education and motivational messaging.

With the UK seeing large increases in years lived with long term conditions and health symptoms, affecting both quality of life for individuals, and strain on services in healthcare, it's crucial to find new scalable ways to increase population self management abilities and overall health and wellbeing.

This report focuses on data collected from over 28,475 Holly Health users in the UK, referred in from NHS primary care GP practices, who completed onboarding questionnaires, and 1824 people who completed both onboarding data and follow up surveys.

The platform uses a "traffic light" and Likert scoring system to assess users' health challenges at baseline, informing personalised content recommendations and coaching. After 8 weeks, users are encouraged to retake the questionnaire to track their progress and update recommendations.

This write up provides an overview of the baseline picture of health amongst this cohort and the average reported health changes, alongside user feedback, after 8 weeks of using Holly Health.
