Case Study: Lark Health achieves a 92% onboarding rate with Branch's deferred deep linking platform

Guiding 92% of New Users Seamlessly Through the Door

Lark Health uses AI, chatbots and connected devices to deliver 24/7 chronic disease management on mobile devices. As a new entrant in a conservative, competitive healthcare market, Lark needed a streamlined, highly personalized onboarding flow to convert installs into engaged users—but faced costly acquisition channels and the risk that users would drop out during installation and registration.

By integrating Branch’s deferred deep linking to enable one‑click registration and pass contextual user data into the app, Lark provided tailored onboarding that reduced friction and reinforced trust. The result: a 92% onboarding rate, stronger early engagement, and user feedback that the chatbot experience feels personal and human.
