Redesign the Daily-Engagement Loop for a Smoking-Cessation App
Overview
What this challenge is about.
Audit a smoking-cessation app’s engagement loop, then redesign it with behavior-change techniques. Earn a verifiable certificate.
The scenario
The stakeholder is the chief executive of a 55-person Copenhagen digital-health startup whose European Union-only smoking-cessation app has plateaued at an 18 percent 30-day quit rate even though its medical content is clinically validated. They need the daily experience redesigned around behavior science, because content quality is no longer the limiting factor — habit formation and daily re-engagement are.
The Brief
What you'll do, and what you'll demonstrate.
Design a behavior-science-grounded redesign of the app's daily-engagement loop that can credibly lift the 30-day quit rate from 18 percent toward 25 percent.
Earning criteria — what you'll demonstrate
- Translate a published behavior-change-technique taxonomy into concrete interaction-design decisions
- Diagnose engagement gaps from quantitative usage data and tie them to behavioral mechanisms
- Design and pre-register a within-subject pilot that controls for order effects and uses defensible metrics
- Produce accessible, mobile-first interface specifications that meet European Union accessibility expectations
- Communicate a design proposal at the rigor expected by an applied human-computer-interaction venue

Completing this challenge demonstrates skills that transfer directly to these roles:
Senior Product Manager, Digital Health
This challenge mirrors the core PM job in health tech: turning a flat retention metric into an evidence-grounded product bet, defending it to leadership, and planning the experiment that proves it before engineering invests.
