App Review Process

Definition

The App Review Process is the submission, review, and approval workflow for apps before distribution on Apple App Store, Google Play Store, and Amazon Appstore. Each platform has distinct pipelines: Apple uses human review (24–48h), Google uses automated + escalation (instant–3 days), Amazon is slowest (2–7 days). Understanding review timelines is critical for ASO planning, as updates with metadata changes, In-App Events, and seasonal launches depend on reliable approval schedules.

How It Works

Apple App Store

Pipeline Overview:

1. Submission (Developer via App Store Connect):

- Upload binary + metadata (description, keywords, screenshots, ratings)

- Auto-validation: IPA signature, embedded frameworks, entitlements

- Build pre-processing: ~5–15 minutes (automated)

- Submission queued; status: "Waiting for Review"

1. Automated Checks (~15–30 minutes):

- Binary analysis: architecture (ARM64), code signing, encryption

- Entitlements verification: Maps, HomeKit, HealthKit, etc. (must match capability claims)

- Content analysis: Metadata for obvious violations (spam, explicit content)

- App size limits, SDK versions, deployment target compatibility

- Status remains "Waiting for Review" during automation

1. Human Review (1–2 humans, 30–60 minutes per app):

- Testers download build on real iOS devices (iPhone, iPad, Apple Watch if applicable)

- Test App Review Guidelines compliance: functionality, safety, UI/UX

- Review metadata: screenshots authenticity, description accuracy, keyword compliance

- Test all In-App Purchase flows, subscription setup

- Test external links, web views, health/payment integrations if present

- Possible outcomes: Approved, Rejected, Needs Info

1. Resolution (if Rejected):

- App goes to status "Rejected"

- Developer receives detailed explanation + guideline reference

- Developer has 30 days to appeal or resubmit fixed version

- Resubmission restarts pipeline (back to automated checks)

1. Post-Approval:

- Status: "Ready for Sale"

- Version becomes available to users within minutes

- Metadata begins ranking in Apple Search Algorithm

Timeline Breakdown:

• Standard: 24–48 hours (90% of apps) from submission to approval/rejection
• Complex (nested APIs, multiplayer, heavy graphics): 3–5 days
• Escalated (policy questions, legal review): 5–7 days
• Expedited review: Available on request; 24-hour turnaround (for time-sensitive releases like seasonal updates)

Expedited Review:

• Request in App Store Connect (new submission only, not updates)
• Requires justification (event deadline, holiday release, etc.)
• Approved by Apple review team discretionally
• Not guaranteed; must submit 48 hours before desired release date

Google Play Store

Pipeline Overview:

1. Submission (Developer via Google Play Console):

- Upload APK/AAB + metadata (description, graphics, screenshots, etc.)

- Automated signature verification: ~30 seconds

- Status: "In Review"

1. Automated Policy Scan (<1 hour, typically <30 minutes):

- Malware scan: VirusTotal, Google Play Protect

- Permissions analysis: Requested permissions vs. declared features

- Content classification: Automatic content rating (ESRB, PEGI)

- Metadata spam detection: Keyword stuffing, misleading claims, cloaking

- APK analysis: Architecture, SDK versions, targeting API level

- Status remains "In Review" during automation

1. Human Review (If Automated Flags Detected, or Random Sample):

- ~5% of submissions escalated for human review (randomized QA)

- Tester downloads app on Android devices; evaluates functionality

- Reviews App Review Guidelines (Google's version) for violations

- Review cycle: <1 hour for escalated apps

- Outcomes: Approved, Rejected, Needs Info

1. Approval:

- Status: "Published"

- App available within 30 minutes to users (some regional delays 2–4 hours)

- Metadata indexed in Google Play Search Algorithm immediately

1. Post-Approval Monitoring (Continuous):

- Android Vitals monitored daily; high crash rate triggers warnings

- Policy compliance re-scanned weekly; violations can result in immediate de-listing

- User review sentiment monitored; fake reviews auto-flagged

Timeline Breakdown:

• Standard: Instant to <1 hour (90% of apps)
• Escalated to human review: 1–3 days
• Rejected (policy) + resubmit cycle: 24–48 hours

Expedited Review: Not available (Google's model is mostly automated; no faster track)

Amazon Appstore

Pipeline Overview:

1. Submission (Developer via Amazon Appstore Developer Console)
2. Automated Checks (~2 hours)
3. Manual Review (Human testers; 2–5 business days)
4. Approval/Rejection + Publishing

Timeline: 2–7 business days total (slowest of the three)

Formulas & Metrics

Average Time to Approval (Industry Benchmarks):

• Apple: 36 hours (median) | 24–72 hours (99th percentile)
• Google: 4 hours (median) | <1 hour–3 days (99th percentile)
• Amazon: 72 hours (median) | 48–168 hours (99th percentile)

Rejection Rate (First Submission):

• Apple: 5–10% (depends on category, complexity)
• Google: 2–5%
• Amazon: 3–7%

Resubmission-to-Approval Cycle:

• Apple: 24–48 hours (fixes typically quick; re-review expedited)
• Google: 2–24 hours (depends on fix complexity)
• Amazon: 24–72 hours

Impact on Update Frequency Planning:

• Apple's slower review means updates planned 2–3 weeks before desired release
• Google's speed allows rapid iteration (same-day patches possible)
• Amazon's slowness makes batch updates preferable

Best Practices

Pre-Submission Strategy

1. Pre-Submission Checklist (48 hours before):

- [ ] Test app on target OS versions and device types

- [ ] Verify all external URLs (links, web views) are live

- [ ] Review App Review Guidelines & compare to app features

- [ ] Screenshot audit: ensure actual app UI, text legible, no edits

- [ ] Metadata audit: keywords natural (no stuffing), description accurate, claims verifiable

- [ ] Data Safety & Privacy disclosure filled out accurately (Apple + Google mandatory)

- [ ] Version notes written (1–2 sentences on what's new)

- [ ] In-App Purchase flows tested end-to-end

- [ ] Build tested on real devices (not just simulator)

1. Timing Strategy:

- Apple: Seasonal releases → submit 3–4 weeks early (plan for rejections + appeals)

- Google: Fast-follow strategy → submit baseline, iterate rapidly after launch

- Amazon: Batch major updates → submit 3–4 weeks prior

1. Metadata Optimization for Review:

- Clear, concise version notes help reviewers understand changes

- Highlight if new In-App Events or Custom Product Pages (CPP) are included

- If using Store Listing Experiments, mention which variant is being reviewed

- Provide test accounts for apps with sign-in (subscription/membership)

Handling Rejections

1. Apple Rejection Handling:

- Read rejection reason carefully; cross-reference guideline section

- Fix issue (don't argue; Apple's decision is final without appeal success)

- Resubmit within 30 days (recommended: within 3–5 days for momentum)

- If appealing, provide evidence (e.g., "this health claim is cited in [study]")

- Track rejection history; pattern of rejections signals spam or low quality

1. Google Rejection Handling:

- Fix issue and resubmit (no formal appeal; iterative process)

- If unsure about policy, test in beta release first (limited testers, lower stakes)

- Re-review timescale: typically 24 hours

1. Multiple Rejections (Red Flag):

- 2+ rejections → app flagged as lower-quality

- May suppress initial ranking post-approval; impacts Download Velocity

- Solution: Address root cause (e.g., is UX broken? metadata misleading?)

Update Frequency Scheduling

• Apple: Plan major Update Frequency every 4–6 weeks; submit 2–3 weeks prior to desired release
• Google: Can maintain rapid cadence (2-week cycle); submit 1 week prior
• Amazon: Plan quarterly major updates; submit 6 weeks prior

Coordinated Multi-Platform Launches:

• If launching simultaneously across Apple/Google/Amazon:

- Submit Apple first (longest review time)

- Submit Google 5 days later (faster, aligns with Apple approval)

- Submit Amazon 10 days later (slowest; coordinate final approval)

- Aim for all 3 platforms live within same week

Examples

Example 1: Seasonal Release (Black Friday)

• Goal: Launch promotional Custom Product Pages (CPP) on Black Friday (Nov 29)
• Timeline:

- Oct 30: Finalize metadata, CPP design, promotional screenshots

- Nov 10: Submit to Apple (3+ weeks for review + potential rejections)

- Nov 17: Submit to Google (1+ week before Apple approval expected)

- Nov 22: Submit to Amazon (7 days before launch; buffer for rejection)

- Nov 28–29: All platforms approved; metadata goes live

- Metric: 80K+ installs on launch day (Black Friday promotional collection feature)

Example 2: Critical Bug Fix

• Goal: Fix crash affecting 5% of user base
• Timeline:

- Day 1: Identify bug; fix in codebase

- Day 2: Build new version; submit to Google (fast track)

- Day 2 (evening): Google approves; fix goes live

- Day 3: Submit to Apple (parallel review)

- Day 4: Apple approves; fix goes live

- Day 5: Submit to Amazon

- Day 10: All platforms have fix live

- Impact: Day 2 Google fix prevents further churn on Android

Example 3: In-App Events Launch

• Feature: New limited-time battle pass (30-day event)
• Timeline:

- 3 weeks prior: Content complete; servers ready

- 2 weeks prior: Submit to Apple with version notes highlighting event

- 1 week prior: Submit to Google

- 6 days prior: Submit to Amazon

- Event launch day: All platforms approved; In-App Events visible

- Result: Coordinated cross-platform event drive +40% DAU during event window
