Launching an app means registering an Apple Developer and Google Play Console account, preparing store listing assets and privacy disclosures, submitting your build for review, and going live once approved. Apple’s review typically takes 24–48 hours; Google Play is usually faster but requires new accounts to complete a mandatory closed test first.

 TL;DR

  • Accounts & fees: Apple Developer Program is $99/year; Google Play Console is a one-time $25 fee. Both are required before you can submit.
  • Assets you need: app icon, screenshots per device size, a written description, a privacy policy URL, a support URL and a content/age rating questionnaire.
  • Apple submission + review: builds go through App Store Connect and App Review, which averages 24–48 hours for a clean submission but can take longer for finance, health or kids’ apps.
  • Google submission + testing: new personal Play Console accounts must run a closed test with at least 12 opted-in testers for 14 continuous days before they can apply for production access.
  • Common rejections: crashes, missing or inaccurate privacy policies, no in-app account deletion, mismatched screenshots, and payment-flow violations.
  • UK privacy disclosures: you need a UK GDPR-compliant privacy policy, Apple’s privacy “nutrition label”, Google Play’s Data safety section, and — if your app might be accessed by under-18s — consideration of the ICO’s Children’s code.

What does launching an app actually involve?

App launch process

Launching isn’t a single event — it’s a sequence of administrative, creative and review steps that typically run in parallel across both platforms. Realistically, budget 2–4 weeks from “app is built” to “app is live” for a straightforward, policy-compliant app on iOS, and slightly longer on Android if you’re a new Google Play developer working through the mandatory testing period. The sequence is broadly: register your developer accounts, prepare your store listing assets and legal disclosures, build and upload your release, complete platform-specific testing or review, then publish. Regulated categories — finance, health, and anything likely to be used by children — tend to take longer on both platforms because they’re routed to more thorough review.

Before you submit: accounts, assets and policies

Before either store will accept a submission, you need an active developer account on that platform, a complete set of store listing assets, a live privacy policy, and — where relevant — a content rating for your app.

Apple Developer account & fee

The Apple Developer Program costs $99 (USD) per year for an individual or organisation account, renewing annually, and covers unlimited app submissions and updates under that account. It also gives you access to App Store Connect, Test Flight (for internal and external beta testing), certificates and provisioning profiles. There’s no separate per-app fee — one membership covers everything you publish. Apple typically verifies identity and, for organisation accounts, your company’s legal registration, which can take a few days, so it’s worth starting this step early rather than leaving it until the build is ready.

Google Play Console account & fee

Google Play charges a one-time $25 registration fee for a Play Console account, with no annual renewal. The bigger consideration for new developers is Google’s closed-testing requirement: personal developer accounts created after 13 November 2023 must run a closed test with at least 12 real, opted-in testers who stay opted in continuously for 14 days before Google will grant production access. Testers who opt out and back in reset that continuous window, so it’s worth recruiting slightly more than 12 to allow for drop-off. This requirement doesn’t apply to organisation (business-verified) Play Console accounts, which is one reason many agencies and studios register as an organisation from the outset.

Store listing assets (icons, screenshots, description)

Both stores require a finished icon at the correct resolution, a set of screenshots sized for each supported device (phone and, where relevant, tablet), a short and long description, keywords, a support URL, and a marketing/promotional text field. Get these details wrong — blurry screenshots, placeholder text, a description that doesn’t match what the app actually does — and you risk a rejection that has nothing to do with your code. Both platforms also require you to complete a content/age rating questionnaire (Apple’s age rating system and Google’s IARC-based rating), which determines how your app is labelled to users and, in some markets, restricts distribution outright if answered inaccurately.

Publishing on the Apple App Store

Once your Apple Developer account is active, the process runs through App Store Connect: create your app record, complete the store listing and age rating, upload your build via Xcode or Transporter, and submit for review. Apple states that most submissions are reviewed within 24 hours, historically around 90% in under a day, though third-party trackers report more variance in 2026 as submission volumes have climbed sharply. Regulated or child-directed categories — Finance, Kids and Health in particular — are routed to senior reviewers and often require licensing or compliance evidence, which adds days rather than hours. If Apple rejects your build, you’ll get a specific guideline reference and a description of the issue; fixing and resubmitting puts you back in the review queue, so a single avoidable rejection can easily add several days to your timeline, and two rejections can add a week or more.

Publishing on Google Play

In Play Console, you create your app, complete the store listing, Data safety section and content rating, then upload your release to a testing track before it can go to production. For accounts created after November 2023, that testing track must be a closed test meeting the 12-tester, 14-day rule described above — this is not optional, and there’s no way to bypass it for a personal account. Once the testing period is complete, you apply for production access through the Play Console dashboard, answering questions about your app’s design, testing process and readiness. Google’s own review of production releases is typically faster than Apple’s, often completing within a few hours to a few days, but the 14-day testing clock is usually the longer pole in the tent for first-time Android publishers.

Common reasons apps get rejected — and how to avoid them

Most rejections on both platforms are preventable with preparation rather than a sign of an unreasonable reviewer. On Apple, crashes and bugs top the list — reviewers test your core user flows manually, and any crash or unresponsive screen triggers an immediate rejection, so a thorough pass on the exact build you’re submitting matters more than testing an earlier version. A missing, inaccessible or inaccurate privacy policy is the next most common cause, closely followed by the absence of an in-app account-deletion flow — required since 2022, and specifically tested for, with an email-based workaround no longer accepted. Screenshots or metadata that don’t match the actual app, broken login or checkout flows, and payment flows that bypass Apple’s or Google’s own in-app purchase systems (routing users to external payment links) round out the biggest categories. A useful habit before every submission: test the exact build you’re uploading end-to-end, re-read your privacy policy against what the app actually collects, and confirm every third-party SDK you use ships an up-to-date privacy manifest — outdated or undisclosed SDK tracking is an increasingly common, and entirely avoidable, rejection trigger.

Rejection trigger Which platform How to avoid it
Crashes or broken core flows Both Test the exact submitted build end-to-end before uploading
Missing/inaccurate privacy policy Both Publish a live, accurate policy URL matching actual data use
No in-app account deletion Apple (Guideline 5.1.1(v)) Add a visible, functional in-app “Delete account” option
Screenshots/description mismatch Both Update listing assets every time the app’s features change
Payment flow bypasses store billing Both Route all digital purchases through StoreKit / Play Billing
Undisclosed third-party SDK tracking Apple (privacy manifests) Audit every SDK’s privacy manifest before each submission

 

 UK-specific requirements

Every app distributed to UK users needs a privacy policy that meets UK GDPR requirements — written in plain language, easily accessible from within the app and the store listing, and accurately describing what personal data you collect, why, and how long you keep it. Both stores also require their own structured disclosures on top of a general policy: Apple’s privacy “nutrition label” in App Store Connect, and Google Play’s Data safety section, both of which ask you to declare, category by category, what data your app collects and whether it’s shared with third parties — and both stores can reject or later remove an app if the declared label doesn’t match what the binary actually does. If your app is likely to be accessed by under-18s in the UK — which the ICO interprets broadly, not just apps explicitly aimed at children — you should assess it against the ICO’s Children’s code (the Age-Appropriate Design Code), which sets 15 standards covering age-appropriate defaults, data minimisation and profiling. Apps with a PEGI rating of 16 or lower generally need to conform to the code; higher-rated apps need robust age assurance to keep under-18s out rather than code conformance for them.

 Launch-day and post-launch checklist

  • Confirm your build is live in both App Store Connect and Play Console, and spot-check the listing on a real device in each store, not just the dashboard preview.
  • Verify your privacy policy URL, support URL and any in-app legal links resolve correctly from the published listing.
  • Check your app’s category, age rating and pricing display correctly for UK users specifically, not just your default market.
  • Set up crash reporting and basic analytics before go-live if you haven’t already, so day-one issues surface immediately rather than via user reviews.
  • Monitor early reviews and ratings closely in the first 48–72 hours; a fast response to a legitimate bug report can prevent a pile-on of low ratings.
  • Plan your first update cycle — Apple and Google both reward apps that ship regular, policy-compliant updates with better visibility than apps that go quiet after launch.
  • Keep your closed-test group (Android) or TestFlight group (iOS) active after launch; you’ll want it again for your next release.

 Frequently asked questions

How long does it take to get an app approved?

Apple's App Store review averages 24–48 hours for a clean submission, though finance, health and kids' apps often take longer due to senior review routing. Google Play's production review is typically faster, but new personal developer accounts must first complete a 14-day closed test with at least 12 testers before applying.

How much does it cost to publish an app?

The mandatory platform fees are $99/year for Apple's Developer Program and a one-time $25 for Google Play Console — around $124 combined in year one, then $99/year after that. Beyond fees, budget for design assets, a hosted privacy policy, and possibly recruiting closed testers for Android.

Why do apps get rejected from the App Store?

The most common causes are crashes or broken flows, a missing or inaccurate privacy policy, no in-app account deletion, screenshots or descriptions that don't match the app, and payment flows that bypass Apple's in-app purchase system. Apple rejects roughly one in four submissions, and most reasons are fixable within a day.

Do I need a privacy policy to launch an app?

Yes — both Apple and Google require a live, accurate privacy policy URL before they'll approve your app, and UK GDPR requires one regardless of store policy if you process any personal data. It must be written in plain language and genuinely reflect what your app collects and shares.

What are Google Play's testing requirements?

Personal developer accounts created after 13 November 2023 must run a closed test with at least 12 real, opted-in testers who stay continuously opted in for 14 days before Google grants production access. Organisation (business-verified) accounts are exempt from this requirement.

Can I launch on one platform first?

Yes, and many teams do — launching iOS or Android first lets you validate demand and fix issues with a smaller footprint before doubling your review and testing overhead. Just bear in mind Google's 14-day closed-testing clock if Android is your second platform, since it needs to run regardless of how polished iOS already is.

What do I need to disclose about data under UK GDPR?

You need to tell users what personal data you collect, your lawful basis for processing it, who you share it with, how long you keep it, and how they can exercise their rights (access, deletion, and so on) — via a plain-language privacy policy, plus the store-specific privacy label (Apple) or Data safety section (Google) that must match it exactly.

What should I do on launch day?

Spot-check the live listing on a real device in each store, confirm your privacy and support links resolve correctly, make sure crash reporting is switched on, and monitor early reviews closely for the first 48–72 hours so you can respond fast to any genuine bugs before they affect your rating.
