Mobile Product Launch & Operations

The Mobile Launch Playbook

PhaseActivities
T-Minus 4 weeksFreeze new features; focus on crash/stability fixes; prepare store listing assets
T-Minus 2 weeksSubmit to TestFlight / closed track; run through full test matrix
T-Minus 1 weekSubmit for production review; prepare support FAQs and internal release notes
Launch dayMonitor crash rate, ratings, and support tickets hourly; stage rollout to 5%
T+1 weekExpand to 100% if metrics are healthy; post-mortem any launch-day incidents

Staged Rollouts

Always start at 5–10%. Google Play and App Store both support percentage-based rollouts. Monitor these metrics before expanding:

  • Crash-free session rate (>99.5%)
  • Rating trajectory (not declining)
  • Key funnels (not regressing)
  • Support ticket volume (not spiking)

Incident Response on Mobile

Mobile incidents are harder to fix than web — no “deploy fix and refresh.” Build a runbook:

  1. Detect via crash reporting and rating alerts
  2. Mitigate — disable the feature via remote config; roll back staged rollout
  3. Fix — develop, test, submit, wait for review
  4. Communicate — update store description, reply to reviews, notify affected users
  5. Post-mortem — add regression tests, improve monitoring

Version Fragmentation

Users don’t all update. Six months after a release, 70–80% of users are on the latest version. Support the last two major versions. Use feature flags to gate features on minimum OS version or app version.

Deprecating Features

Removing a feature from a mobile app is harder than adding one. Users who rely on it will leave angry reviews. Deprecation process:

  1. Announce timeline in-app and via email/notification (3 months notice)
  2. Replace or consolidate the feature where possible
  3. Degrade gracefully — show read-only view, then remove
  4. Monitor support tickets and rating impact during deprecation

Ongoing Operations

  • Weekly crash triage
  • Monthly store listing optimisation (A/B test screenshots and descriptions)
  • Quarterly app store Q&A review — respond to every review, especially negative ones
  • Bi-annual platform guideline audit — both Apple and Google update guidelines yearly
