Why does this churn problem matter?
Mobile users have 2-3x higher churn than desktop users, but 40-60% of your traffic is mobile. Your responsive web design barely works on phones, core workflows are impossible to complete without a computer, and your iOS/Android apps are outdated. Users sign up on mobile, can't complete activation tasks, and churn within days. You're losing the "check on the go" segment entirely.
How do we solve it?
Audit mobile user journey, identify critical workflows that must work on mobile, and build lightweight mobile experiences for those flows. Don't try to replicate full desktop product - focus on 3-5 "mobile moments" users need (check status, approve requests, view reports, respond to alerts). Progressive Web App (PWA) often better than full native apps.
How do you implement it step by step?
-
1
Analyze mobile user behavior: what do they try to do? Where do they fail?
-
2
Identify 3-5 critical mobile workflows: what must work on small screens?
-
3
Audit current mobile experience: test every workflow on iPhone/Android
-
4
Prioritize fixes: responsive design improvements vs native app vs PWA
-
5
Build mobile-optimized flows for critical tasks (approval flows, dashboards, alerts)
-
6
Create mobile onboarding: 2-3 steps max, swipe-based, immediate value
-
7
Add offline mode for mobile: cache key data, sync when connected
-
8
Test with real mobile users: watch them complete tasks on small screens

What outcome should you expect?
Reduce mobile user churn from 2-3x desktop to within 20% of desktop. Increase mobile activation rate by 50%. Expand mobile user segment from 20% to 40% of active users. Unlock "on the go" use cases.
How do you measure if it's working?
Track these metrics to know if the experiment is working:
- Mobile vs desktop churn rate ratio
- Mobile activation rate (completing key action within 7 days)
- Mobile monthly active users as % of total
- Mobile workflow completion rates
- Mobile session duration and engagement
- App store ratings (if native apps)
What do you need before you start?
Make sure you have these before starting:
- Mobile analytics: separate tracking for mobile web, iOS, Android
- Mobile user research: interviews with mobile-first customers
- Product/engineering resources for mobile development
- At least 30% of users accessing product on mobile
- Decision on mobile strategy: responsive web vs PWA vs native apps
What mistakes should you avoid?
Don't make these errors that cause experiments to fail:
- Building native apps before optimizing responsive web
- Trying to replicate full desktop product on mobile
- Not testing on actual small screens (iPhone SE, not iPad)
- Ignoring mobile-specific workflows (push notifications, camera, location)
- Mobile web experience as afterthought in product roadmap
- Not measuring mobile vs desktop metrics separately

Retention Diagnostic
Knowing the number is not the same as knowing the cause
A calculator tells you how much is leaving. It cannot tell you which part is failed payments, which part is people who never activated, and which of the two is cheaper to fix. I work that out on your actual data and send back three fixes ranked by what each one is worth, within 10 working days.
- ✓ Voluntary and involuntary churn, split and costed
- ✓ What the leavers did in their first month
- ✓ Three fixes, ranked by dollars recovered
- ✓ Fixed price, written, no call required
