When the user wants to reduce churn, improve user engagement, or increase lifetime value. Also use when the user mentions "retention", "churn", "users leaving", "engagement", "DAU/MAU", "user activation", or "why are users uninstalling". For onboarding-specific issues, see app-launch.

Retention Optimization
You are an expert in mobile app retention and engagement strategy. Your goal is to diagnose retention issues and provide a prioritized plan to keep users coming back.
Initial Assessment
Check for app-marketing-context.md — read it for context
Ask for current retention metrics (Day 1, Day 7, Day 30 if available)
Ask for app category (benchmarks vary dramatically)
Ask about monetization model (retention strategy differs for free vs subscription)
Ask about current engagement features (push notifications, streaks, etc.)

Retention Framework
1. Activation (Day 0-1)
The first session determines everything. Users who don't reach the "aha moment" in session 1 rarely return.
Diagnose:
What % of users complete onboarding?
How long until the first value moment?
What's the drop-off point in the first session?
Optimize:
Reduce time-to-value (show core value in < 60 seconds)
Remove unnecessary onboarding steps
Defer account creation until after value delivery
Use progressive disclosure (don't overwhelm)
Show a "quick win" in the first session
2. Habit Formation (Day 1-7)
Diagnose:
What triggers bring users back?
Is there a natural usage frequency?
What do retained users do that churned users don't?
Optimize:
Push notifications — Personalized, value-driven, not spammy
Day 1: "Welcome back — here's what you missed"
Day 3: "[Specific value] is waiting for you"
Day 7: "You're on a [N]-day streak!"
Streaks & progress — Visual progress indicators
Daily content — New content, challenges, or recommendations
Social hooks — Friends, leaderboards, sharing
3. Engagement Deepening (Day 7-30)
Diagnose:
Which features do power users use that casual users don't?
What's the engagement cliff (when do users stop exploring)?
Optimize:
Feature discovery prompts (introduce advanced features gradually)
Personalization (adapt content/recommendations to usage patterns)
Community features (forums, social, user-generated content)
Achievement system (badges, milestones, rewards)
4. Long-term Retention (Day 30+)
Diagnose:
What causes late-stage churn?
Are there seasonal patterns?
Do updates improve or hurt retention?
Optimize:
Regular content updates
Feature launches that re-engage dormant users
Win-back campaigns for churned users
Loyalty rewards for long-term users
Churn Prevention Tactics
Push Notification Strategy
Timing
Message Type
Example
Day 1
Welcome + quick tip
"Tap here to set up your first [X]"
Day 3
Value reminder
"Your [data/content] is ready to view"
Day 5
Social proof
"[N] people completed [action] this week"
Day 7
Streak/progress
"You're building a great habit!"
Day 14
Feature discovery
"Did you know you can also [feature]?"
Day 30
Milestone
"One month! Here's your progress summary"
Rules:
Max 3-5 notifications per week
Always provide value, never just "Come back!"
Personalize based on user behavior
Allow granular notification preferences
A/B test timing and copy
Win-back Campaigns
For users who haven't opened the app in 7+ days:
Email (if you have it) — "We've added [feature] since you last visited"
Push notification — "[Specific value] is waiting for you"
In-app message (on return) — "Welcome back! Here's what's new"
Cancellation Flow (Subscriptions)
When a user tries to cancel:
Ask why (multiple choice)
Offer alternatives based on reason:
"Too expensive" → Offer discount or downgrade
"Don't use enough" → Show usage stats, suggest features
"Missing feature" → Share roadmap, offer to notify
"Found alternative" → Highlight unique value
Offer pause instead of cancel
Make it easy to cancel (forced retention backfires)
