Publishing to App Stores

When your app is ready for real users, AppX handles the hard part. You submit in AppX, and our team builds the native apps and delivers them to the App Store and Google Play under your developer accounts.

No Xcode, no Android Studio, no native build setup on your side.

How it works​

You submit your app in AppX
    ↓
Our team reviews it for quality and store compliance
    ↓
We build the native apps (iOS and Android)
    ↓
We submit to the App Store and / or Google Play under your accounts
    ↓
You're notified once it's live

Before you submit​

Developer accounts​

The stores require apps to be published under a developer account that you own:

You provide access securely during submission so we can publish on your behalf.

App identity​

In Project Settings → Publishing, set:

  • App name — what shows under the icon on the home screen
  • Bundle ID (iOS) — e.g. com.yourcompany.yourapp
  • Package name (Android) — e.g. com.yourcompany.yourapp
  • Version — e.g. 1.0.0

Icon and splash screen​

In Project Settings → Assets:

  • Upload a 1024×1024 PNG app icon — no transparency, no rounded corners (the OS rounds them for you)
  • Upload a splash screen image (around 1284×2778 PNG works well)

AppX generates every icon size iOS and Android need from your 1024×1024 source.

Submitting​

  1. Open your project
  2. Go to Project Settings → Publishing
  3. Confirm your app identity, icon, and splash screen are set
  4. Click Submit for Review

We'll review your app and reach out if anything needs a tweak before we send it to the stores.

How long it takes​

Turnaround depends on your plan and how complex the app is — paid plans are faster, and Pro gets priority handling. See Plans & Pricing for details.

note

After we submit, Apple and Google run their own reviews on their own schedules. Apple typically takes a day or two; Google Play is often a few hours.

Shipping updates​

  1. Make your changes in AppX
  2. Bump the version in Project Settings → Publishing
  3. Click Submit for Review again

We handle the rebuild and resubmission.

Store screenshots​

The stores need screenshots at specific sizes:

iOS

  • iPhone 6.9" (e.g. iPhone 16 Pro Max): 1320×2868
  • iPhone 6.5": 1242×2688
  • iPad Pro 12.9": 2048×2732

Android

  • Phone: at least 320×568
  • Tablet: optional but nice to have

The easiest way to capture them: open your app in Expo Go and screenshot right from your phone.
