Redesign the Daily-Engagement Loop for a Smoking-Cessation App
Overview
What this challenge is about.
Redesign the Daily-Engagement Loop for a Smoking-Cessation App. Expert-level challenge in design. Designing real products under real constraints, earn a bloc...
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.
This is not a design exercise. It is the work a product designer does between a brief and a shipped interface. That distinction matters to every hiring manager who has seen candidates redesign Spotify's homepage and none who have worked under real product constraints.
When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."
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.
