Growth & Retention for Mobile Apps

Push Notifications

The most powerful engagement tool on mobile — and the most abused. Permission rates vary: 60–70% for utility apps, 40–50% for content apps, under 30% for marketing-heavy apps.

Best practices:

  • Request permission in context (“Get notified when your order ships”), not at launch.
  • Segment by user behaviour — don’t send the same blast to everyone.
  • Support notification categories for user preference control.
  • Measure not just delivery but tap-through and downstream action.

Deep Linking

Deep links take users directly to specific content within your app. Universal links (iOS) and App Links (Android) are the modern approach — they don’t trigger a confirmation dialog.

Use deep links in:

  • Push notifications
  • Email campaigns
  • SMS referrals
  • QR codes
  • Cross-app navigation

Referral Programmes

Referral works well on mobile because the share sheet is built in. Reduce friction:

  • Provide a shareable link that deep links to the app store.
  • Reward both referrer and referee.
  • Track referral conversions with unique codes or fingerprinting.

App Clips & Instant Apps

App Clips (iOS) and Instant Apps (Android) let users experience a piece of your app without installing it. Use them for:

  • Point-of-sale payments
  • Rental check-in / check-out
  • Event ticketing
  • Food ordering

Re-engagement Campaigns

Users who churn can be won back. Strategies ranked by effectiveness:

  1. Personalised push with a specific value prop (“Your cart items are back in stock”)
  2. Email with deep link to a personalised offer
  3. SMS (high-risk — use only with opt-in)
  4. App store search ads targeting lapsed users
