Mobile App Launch Checklist

Mobile App Launch Checklist

Generate a structured, actionable launch checklist tailored to the user's app, target platform(s), and timeline. Walk through each phase sequentially, confirm completion of critical items, and flag blockers.

iOS top rejections:

• Crashes or bugs during review
• Broken links (privacy policy, support URL)
• Incomplete metadata or placeholder content
• Login required without demo account provided
• Guideline 4.3: spam or duplicate app

Google Play top rejections:

• Data safety form inaccurate or incomplete
• Missing privacy policy for apps requesting sensitive permissions
• Deceptive behavior (description doesn't match functionality)
• Broken core functionality
• Target audience misconfigured (apps for children have extra requirements)

Phase 4: Launch Day

Follow the hour-by-hour launch day timeline in references/launch-day-timeline.md for a detailed execution plan.

Release Strategy

• iOS: Release manually (not automatically after approval) for control
• Android: Staged rollout at 10-20% initially
• Coordinate release timing across platforms (if launching on both)
• Choose launch time: Tuesday-Thursday, 9-10 AM in primary market timezone

Monitoring (First 6 Hours)

• Watch crash-free rate in real-time (target: >99.5%)
• Android: Monitor ANR (App Not Responding) rate (target: <0.5%)
• Check App Store Connect / Play Console for review alerts
• Monitor support channels for user-reported issues
• Track download velocity against projections
• Watch first user reviews and ratings

Support Readiness

• Prepared responses drafted for common issues:
  • Login/account problems
  • Payment/subscription questions
  • Feature explanations
  • Known issues acknowledgment
• Support team briefed on new features and known limitations
• Escalation path defined for critical issues

Marketing Activation

• Social media posts scheduled (Twitter/X, LinkedIn, Instagram)
• Product Hunt launch prepared (if applicable — launch at 12:01 AM PT)
• Reddit posts in relevant subreddits (follow community rules)
• Press outreach sent to relevant journalists/bloggers
• Email announcement sent to waitlist/existing users
• App Store / Play Store promotional campaign activated (if using)

Go/No-Go Decision Points

• Halt rollout if: crash-free rate drops below 99%, critical bug in core flow
• Proceed to 50% if: 4+ hours stable, no critical issues, reviews positive
• Proceed to 100% if: 24+ hours stable at 50%, metrics within targets

Phase 5: Post-Launch (Week 1)

Review Management

• Respond to every review (positive and negative) within 24 hours
• Flag and report fraudulent/spam reviews
• Categorize feedback themes for product roadmap input
• iOS: Implement SKStoreReviewController for in-app review prompts (after positive moments, max 3 times per 365 days)
• Android: Implement In-App Review API (after meaningful engagement)

Crash Triage & Hotfix

• Review crash reports daily for the first week
• Prioritize crashes by user impact (affected users x severity)
• Ship hotfix within 48 hours for any crash affecting >1% of users
• iOS: Request expedited review for critical hotfixes
• Android: Use staged rollout to validate hotfix before full release

Metrics Review

Track and review these metrics at Day 1, Day 3, and Day 7:

Feature Request & Visibility

• Submit App Store feature request to Apple editorial team (via App Store Connect → App Features page)
• Apply for Google Play editorial feature (via Play Console → Store presence → Feature request)
• Compile feature request list from user feedback for v1.1 planning
• Schedule v1.1 planning session based on launch data

Generating the Checklist

When producing the checklist for the user:

1. Tailor to platform. Remove iOS-specific items for Android-only launches and vice versa. Keep both sections for cross-platform launches.
2. Adjust timeline. Map checklist phases to the user's actual launch date. Add specific dates to each phase header.
3. Flag blockers. Mark items that block submission (privacy policy, app icon, signed build) distinctly from nice-to-haves (preview video, Product Hunt).
4. Save as file. Write the completed checklist to LAUNCH-CHECKLIST-{AppName}.md in the project root.
5. Offer to deep-dive. After generating the checklist, ask if the user wants to walk through any specific phase in detail, referencing the appropriate reference file.
