Overview & definitions

Acquisition gets the spotlight, but sustainable growth comes from helping existing users return and succeed. Reengagement nudges inactive users back to the app; retention is the ability to keep them active over time. Deep links and verified web-to-app flows reduce friction so users land on the exact screen where value happens.

App reengagement

Tactics that encourage dormant or less-active users to return and resume activity.

App retention

Keeping existing users active across time windows (D, W, M) — a strong signal of value and UX fit.

Barriers to engaging and retaining app users

Crowded markets

Alternatives are one tap away. If value isn’t immediate and repeatable, users drift.

Friction & poor UX

Extra steps, confusing IA, and dead-end links erode trust and session depth.

Ineffective onboarding

If “day 0” doesn’t show the payoff, users won’t come back for “day 1”.

How to measure engagement and retention

Engagement metrics

  • Active users: DAU / WAU / MAU.
  • Session length: Time per session.
  • Time in app: Time across a window.
  • Key interactions: Taps, views, feature use.
  • Conversion rate: (Conversions / Active users) × 100.

Retention metrics

  • Session interval: Time between sessions (lower is better).
  • Inactivity window: Time since last activity.
  • Retention rate: (Users active in window / Installs in cohort) × 100.
  • Churn rate: (Users who churned / Users at start) × 100.

Strategies to reengage and retain app users

1) Analyze user behavior and feedback

Map the journey, find friction, and A/B test fixes. Track screen flows, drop-offs, load times, and crashes. Pair quant with qualitative input from in-app surveys and interviews to uncover motivations and blockers.

2) Personalize user experiences

Use behavioral and contextual signals to tailor content. Deep links let you deliver users to the most relevant screen (e.g., saved cart, playlist, lesson) with fewer taps and higher intent.

3) Use push notifications

  • Earn opt-in with value (alerts, progress, perks).
  • Segment by lifecycle and recent behavior.
  • A/B test timing, copy, and CTA deep links.
  • Throttle frequency; make it easy to manage preferences.

4) Deploy in-app messages and offers

Use banners, modals, and tooltips to highlight new features, unstick users, and promote relevant offers. Tie CTAs to deep links that advance users along a clear path.

5) Integrate social media

Encourage sharing of milestones or creations with pre-filled share sheets. Social posts can deep link new and existing users back to in-app content.

6) Incentivize referral programs

Reward both referrer and friend. Use unique, branded links that carry referral codes through install, so the first session is already personalized.

7) Leverage email marketing campaigns

Email is a high-frequency touchpoint. Always deep link to in-app destinations (not the home screen) to reduce drop-off and increase completion.

8) Personalize the onboarding experience

Start with intent-based paths, short wins, and clear progress. Pull any pre-install context (campaign, goal, referral) so first launch feels tailored.

9) Target users with reengagement ads

Retarget dormant cohorts with value-driven messaging (e.g., “Finish setup”, “New episodes”, “Price drop”). Link directly to the screen where the promise is fulfilled.

10) Implement smart banners

Bridge mobile web to app. Use lightweight banners or interstitials with clear value, respectful frequency caps, and A/B-tested copy. Always deep link into the app.

Top tips for a successful strategy

  • Optimize the path: Every campaign should land users on the most relevant in-app screen via deep link.
  • Experiment relentlessly: A/B test messages, placements, incentives, and timing. Keep a changelog.
  • Compare holistically: Measure lift across paid, owned, and earned channels with clean, first-party link data.
  • Start narrow, scale fast: Prove impact on one high-value flow, then templatize to other teams.

FAQ

Do we need an SDK for reengagement flows?

Not strictly. SDKs simplify cold start and payload delivery, but you can implement a REST-only approach if you prefer minimal dependencies.

How do we handle in-app browsers reliably?

Use verified domains (iOS Universal Links / Android App Links) and, when needed, a lightweight intermediate page to preserve context before sending users to the store.

What should push frequency look like?

Base cadence on user value and behavior. Segment by lifecycle, set caps, and offer preference controls. Test and monitor opt-out rates.
