Samsung Health 3.0
Redesigning Samsung's 300M-user health platform around daily wellbeing, not data overload
Samsung Health had 300 million registered users but a daily active rate of just 18% — people opened it when they hit their step goal, then closed it. The data was rich, but it wasn't actionable. Users felt lectured, not guided.
Research Insights
We ran 48 user interviews across five countries (Korea, USA, Brazil, Germany, India) and analysed six months of in-app behaviour data. Three themes dominated.
Data without context
Users saw "7,432 steps" but had no idea if that was good, bad, or what to do with it. Numbers without narrative created anxiety, not motivation.
Notification fatigue
Power users received up to 28 health notifications a day. Most were dismissed within 2 seconds. The signal-to-noise ratio was broken.
No sense of progress
Daily metrics reset at midnight. Users with a bad morning felt like the day was already lost. There was no weekly or monthly arc to lean into.
Design Strategy
The redesign question wasn't 'how do we show more data?' It was 'how do we help people feel like health is working for them, not against them?'
— Atul Chhabra, Product Designer
We shifted the information architecture from metric-first to moment-first. Instead of presenting heart rate, sleep, and activity as equal pillars, the app now surfaces what's most relevant to you based on time of day, recent patterns, and stated goals.
Contextual Home Screen
The new home card adapts throughout the day. At 7am it shows sleep quality and readiness score. At noon it nudges toward movement. At 9pm it prepares the sleep wind-down. One screen, many modes.
Narrative Metrics
Raw numbers are now accompanied by a one-line interpretation: '7,400 steps — on track for your weekly average.' The system uses your personal baseline, not generic targets.
Weekly Arc
A new 'This Week' summary card shows a 7-day trend at a glance. A bad Tuesday doesn't reset the story — it's contextualised within the week, keeping momentum alive.
Smart Notification Batching
Reduced notification volume by 68% by batching related nudges into a single daily digest (default: 6pm). Critical alerts (AFib detection, abnormal heart rate) still fire immediately.
Outcome
Samsung Health 3.0 launched in October 2022 with One UI 5. The redesigned home screen and contextual narrative drove the largest single-quarter jump in DAU in Samsung Health's history. The smart notification batching became the template for Samsung's cross-app notification strategy in One UI 6.
