Publish to App Stores

Wrap your published PWA with PWA Builder to generate Android, iOS, and Windows packages. A guided in-builder flow is on the roadmap.

Proyecta builds web apps. To distribute through the App Store, Google Play, or Microsoft Store, you wrap your published app as a PWA and use a tool like PWA Builder to generate native packages.

Step 1: Make sure your app is a PWA

Before generating store packages, ask the AI to add PWA support:

Add PWA support to my app:
- Web app manifest with name, short name, icons (192px and 512px), theme color
- Service worker that caches the app shell for offline use
- Install prompt

Then publish to your *.proyecta.live subdomain (or a custom domain).

Step 2: Generate store packages

1. Open pwabuilder.com
2. Enter your published URL
3. PWA Builder runs a manifest/service worker/security audit
4. Click Package for Stores and pick a target:
   • Android — generates an .aab (Android App Bundle) for Google Play
   • iOS — generates an Xcode project you build and submit via Xcode + Transporter
   • Windows — generates an .msix for the Microsoft Store

Step 3: Submit

Each store has its own developer console:

Store	Developer fee	Notes
Google Play	$25 one-time	Generally permissive of PWA wrappers
Apple App Store	$99/year	Apple may reject apps that are just a webview without native functionality. Add native features (push, share, camera) via web APIs to strengthen your case.
Microsoft Store	$19 one-time (individual)	Most permissive

Critical: save your Android signing key

When PWA Builder generates an Android package, it issues a signing.keystore file. Save this somewhere safe — Google Play requires every future update to be signed with the same key. Lose it and you can’t update your app, only republish under a new package name.

The same applies to iOS provisioning profiles and Windows certificates.

Updating after launch

Most updates don’t require a new store submission. Because the wrapped app loads from your published Proyecta URL, content and functionality changes are live the moment you publish. You only need to re-submit a new package when you change:

• App name, icon, splash screen
• Manifest entries the wrapper bakes in
• Native permission declarations
