Lumio — AI Filters
D30 retention dropped from 45% to 31% three weeks after launching 20 AI photo filters.
The scenario
Lumio is a mobile photo-editing app. Three weeks ago you launched 20 AI-powered filters as a headline feature. Initial installs spiked 30%, but D30 retention has fallen sharply. App Store reviews mentioning "filters" have tripled, sentiment is mixed.
Constraint
You have a 3-day sprint with 1 designer to act on this.
Your task
Diagnose the retention drop and propose one fix you can ship this sprint.
1. Clarify: What do you need to know before diagnosing?
Pick the 3 questions you'd ask first.
Model approach (strong picks)
- Strong pickIs the retention drop isolated to users who used the AI filters, or is it app-wide?
- Strong pickWhat do the App Store reviews say — are users complaining about quality, discoverability, or something else?
- Strong pickDid retention start dropping immediately at launch, or after a delay?
2. Hypothesize: What are the most likely causes of the drop?
Pick the 3 hypotheses you'd investigate first.
Model approach (strong picks)
- Strong pickFilter quality is inconsistent — results look bad on certain photo types, killing trust.
- Strong pickToo many filters with no guidance — users are overwhelmed and give up.
- Strong pickThe filters are buried in the UI — most users never find them after the first session.
3. Investigate: What do you do in the next 48 hours?
Pick the 3 highest-leverage moves.
Model approach (strong picks)
- Strong pickSegment D30 retention by users who used ≥1 filter vs. those who never used one.
- Strong pickRead the App Store reviews mentioning filters — tag themes (quality, UX, performance).
- Strong pickCheck the filter usage funnel: how many users open the filter panel, apply a filter, save a photo.
4. Propose: What do you ship this sprint?
Pick the one fix you'd commit to.
Model approach (strong picks)
- Strong pickReduce visible filters from 20 to 5 curated "Starter" picks, with a "See all" option — lower overwhelm, preserve depth.
- Strong pickAdd a short onboarding card on first open that highlights the top 3 filters with example photos.
