Ping An Health

Ping An Health, one of China's largest insurance companies, had partnered with Vitality to modernise its Le Jian Kang wellness app within WeChat. The existing experience needed a fundamental redesign to enhance user engagement and integrate key shared-value wellness mechanics.

The constraints were significant: a hard two-week deadline, a complex existing platform with millions of active users, cultural adaptation requirements for the Chinese market, an unfamiliar tech stack, and the need to work within WeChat's specific platform limitations. Any changes had to improve the experience without disrupting existing user habits.

I led the end-to-end redesign and kept collaboration tight between the Vitality and Ping An teams:

• ▸Dug into the existing app and its WeChat integration and identified where we could improve and grow
• ▸Led daily sprint sessions with Ping An leadership to design and deploy the new mobile experience
• ▸Led the UX/UI revamp, including cultural adaptation, the new tech stack, and WeChat-specific constraints
• ▸Kept design consistent with Vitality's design system while fitting Ping An's brand
• ▸Used rapid prototyping to test and validate design decisions under severe time pressure

With only two weeks, there was no room for extended discovery. I ran the engagement as a compressed design sprint, moving from analysis to delivery in daily iterations.

The first phase was a deep-dive audit of the existing Le Jian Kang app: mapping user flows, finding friction points, and pinpointing where Vitality's shared-value mechanics could be integrated.

I then led the team through a new experience that kept Le Jian Kang's core framework but added critical features:

• ▸Device and app connectivity for automatic health tracking
• ▸Physical activity tracking integration
• ▸A virtual currency reward system to incentivise healthy behaviour
• ▸An upgraded wheelspin mechanic with higher-value rewards
• ▸A smarter health assessment (powered by Healthy Futures) for personalised insights

At the same time, we revamped the full UX/UI, including cultural adaptation for Chinese users and WeChat-specific constraints. Every design decision was validated through rapid prototyping and stakeholder review the same day.

We delivered the redesigned app on time: a full overhaul of a live product serving millions of users, in two weeks. The project strengthened the Ping An–Vitality partnership and raised the bar for user engagement on the Le Jian Kang platform.

The timeline proved that with the right methodology, deep UX audits and redesigns don't need months of runway. Clear process, daily alignment, and rapid prototyping can deliver enterprise-grade results under tight constraints.
