Daily Missions

Turning a library into a personal trainer. Users opened the app and faced a library with no guidance. Daily Missions replaced it with one algorithm-assigned task per day, built around the Watch → Activate → Speak learning loop.

Executive summary

RealLife English had great content and a compelling methodology. What it didn't have was a path. Users opened the app and faced a library with no guidance. Daily Missions replaced the open-ended library with a single, algorithm-assigned task per day, structured around the Watch → Activate → Speak learning loop.

In an A/B test with new users, the new version beat the old one on every retention day with data: day 1 +12%, day 2 +18%, day 7 +27%, week 1 +14%, week 2 +20%. Rollbacks were very low for a full UX redesign. Results were measured right after launch, before any optimization.

The bet held for premium users. The open problem: most free users who complete one mission never return. That is a trigger problem, not a product problem.

PM signals

  • Full lifecycle ownership: strategy through measurement, no PM above, no dedicated specialists below. Every research session, sprint, design decision and data question had major influence from me.
  • Research-driven stakeholder alignment: used behavioral evidence to shift a product leader's preference, then collaborated to reach a stronger outcome than either starting position.
  • Causal thinking in measurement: A/B test designed to isolate the product's effect from YouTube content, push campaigns and seasonal variation. Same cohort window, new users only.
  • Honest impact reporting: distinguished directional signals from confirmed results. Flagged confounds proactively: a scarcity timer bug, an onboarding event gap, early-adopter self-selection in CSAT.
  • Commercial diagnosis: identified that flat conversion reflected a free-tier activation gap preceding monetization, not a product quality or pricing problem. Handed off as prioritized input for the next roadmap phase.

Hands-on: product designer hybrid

I redesigned the transition art direction, the onboarding and the app's core screens, ran usability tests, and redesigned the new free and premium limits and flows.

Key visual and communication for the migration campaign. Users opted in before the sunset date.
