How to Launch an App on the App Store: Step by Step
How to launch an app on the App Store: prepare assets, complete Apple's review requirements, and submit through App Store Connect.
Launching an app on the App Store requires preparing all required assets (screenshots, description, privacy policy), completing Apple's technical and content review requirements, and submitting through App Store Connect for review, which typically takes 24-48 hours. Missing metadata, broken links, or unclear functionality are the most common reasons first submissions get rejected.
Key takeaways:
- App Store review typically takes 24-48 hours, but rejections can add days or weeks
- A privacy policy is mandatory even for apps that don't collect obvious personal data
- Metadata and screenshot quality significantly affect post-launch download rates
- Testing on real devices before submission catches issues automated testing misses
App Store Launch Checklist
| Requirement | Details |
|---|---|
| Apple Developer account | Active enrollment ($99/year) required before submission |
| App icon and screenshots | High-resolution assets meeting Apple's exact size specs |
| App description and keywords | Clear, accurate description; relevant App Store search keywords |
| Privacy policy | Required even for apps with minimal data collection |
| Age rating questionnaire | Completed accurately within App Store Connect |
| Test build (TestFlight) | Recommended before final submission to catch bugs |
How Long Does Apple's App Store Review Actually Take?
Most app submissions are reviewed within 24 to 48 hours, though this can extend during high-volume periods or if the app requires additional manual scrutiny for sensitive categories like health or finance apps. Building in buffer time before a planned launch date — rather than submitting right up against a deadline — avoids unnecessary launch-day stress.
What Are the Most Common Reasons Apps Get Rejected?
Common rejection reasons include incomplete app functionality, crashes during review testing, missing or inadequate privacy policies, and misleading screenshots or descriptions that don't match actual app behavior. Apps that link to features not yet available, or that request permissions without clear justification, are also frequently flagged.
A fitness app that requests location access without explaining why in the permission prompt, for example, is a common and easily avoidable rejection reason — a one-line justification in the permission dialog often resolves it.
Do I Need a Privacy Policy Even If My App Doesn't Collect Personal Data?
Yes — Apple requires a privacy policy URL for every app, regardless of how much data it collects, even if the policy simply states that no personal data is gathered. This is one of the most commonly overlooked requirements for first-time app submitters and an easy rejection to avoid with basic preparation.
How Is Publishing on Google Play Different From the App Store?
Google Play's review process is generally faster and more automated, often completing within a few hours, though it still requires similar assets — screenshots, descriptions, privacy policy, and content rating. Google Play also allows staged rollouts, letting you release an app update to a small percentage of users before a full release, which Apple doesn't offer in the same way.
“"Most first-time app rejections aren't about the app being bad — they're about missing a specific piece of documentation or a permission explanation Apple's reviewers expect to see clearly stated." — the pattern behind most avoidable rejection delays we see.”
Pre-Submission Testing Checklist
- Test on multiple real devices, not just a simulator, across different iOS versions
- Verify every link and button functions as expected, with no placeholder content
- Confirm permission requests include clear, contextual explanations
- Double-check screenshots accurately represent current app functionality
- Complete the age rating and content questionnaire accurately

Preparing for a Strong Launch, Not Just Approval
Getting approved is only the first milestone — a strong launch also depends on App Store Optimization (ASO): relevant keywords in your app title and description, compelling screenshots, and early reviews. Many businesses focus entirely on passing review and neglect the discoverability work that determines whether anyone finds the app once it's live.
Frequently Asked Questions
Q: How much does it cost to publish an app on the App Store?
A: The Apple Developer Program costs $99 per year, separate from any development costs incurred building the app itself.
Q: Can I update my app after it's approved without going through full review again?
A: Most updates still go through App Store review, though the process is typically similar in length to the initial submission review.
Q: What happens if my app gets rejected?
A: Apple provides specific rejection reasons through App Store Connect; addressing the cited issue and resubmitting usually restarts a standard review cycle.
Q: Do I need a separate submission for iPad and iPhone versions?
A: No, a single universal app submission can support both iPhone and iPad if built with responsive layouts for both screen sizes.
