How to Convert Your Website into an Android or iOS App

Many businesses want their website "as an app" so customers can open it from their home screen and get notifications. There are four honest ways to do it, from free and quick to expensive and powerful, and the app stores reject some shortcuts outright. This guide explains each option, what it costs, and how to choose.

1. The four options at a glance

2. First, fix the website

Every option shows your website inside an app frame, so the app is only as good as the site. Before anything else:

• make the layout fully responsive, with buttons large enough to tap;
• serve every page over HTTPS;
• make pages load quickly on a mid-range phone and a mobile connection;
• remove pop-ups and elements that only work with a mouse.

Many businesses find that a fast mobile website is all they needed, and skip the app.

3. Option 1: make it a Progressive Web App

A PWA is a normal website with two extra files: a web app manifest (the name, icons and colours) and a service worker (a script that caches files and can receive push notifications). Browsers then offer to install it, and it opens full-screen from the home screen like an app.

A minimal manifest, saved as manifest.webmanifest and linked from every page's head section:

{
  "name": "Sharma Sweets",
  "short_name": "Sharma",
  "start_url": "/",
  "display": "standalone",
  "background_color": "#ffffff",
  "theme_color": "#b91c1c",
  "icons": [
    { "src": "/icons/icon-192.png", "sizes": "192x192", "type": "image/png" },
    { "src": "/icons/icon-512.png", "sizes": "512x512", "type": "image/png" }
  ]
}

On Android, Chrome shows an install prompt and PWAs support push notifications. On iPhone and iPad, users install from Safari with Share › Add to Home Screen; web push works for PWAs added to the home screen on recent iOS versions, but there is no automatic install prompt. WordPress sites can add PWA support with a plugin.

4. Option 2: publish your PWA on Google Play

A Trusted Web Activity (TWA) is a small Android app that opens your PWA full-screen in Chrome, with no browser address bar. Google's Bubblewrap command-line tool and the free PWABuilder website generate the Android project from your PWA's address.

To prove you own the website, you publish a Digital Asset Links file at https://yourbusiness.in/.well-known/assetlinks.json, containing your app's package name and signing-key fingerprint:

[{
  "relation": ["delegate_permission/common.handle_all_urls"],
  "target": {
    "namespace": "android_app",
    "package_name": "in.yourbusiness.app",
    "sha256_cert_fingerprints": ["AB:CD:...:EF"]
  }
}]

If the file is missing or wrong, the app still opens but shows a browser bar at the top. Use the fingerprint of the key Google Play signs with, shown in Play Console under app integrity.

5. Option 3: a WebView wrapper

A wrapper is a small native app whose only screen is a WebView showing your site. Frameworks such as Capacitor make this straightforward, and paid conversion services build one from your URL.

If you build a wrapper yourself, keep it secure:

• load only your own HTTPS domain, and open other links in the system browser;
• never disable Apple's App Transport Security or allow plain-HTTP traffic to fix a loading problem; switch the site to HTTPS instead;
• only expose native functions to JavaScript that your own pages need.

6. Option 4: a cross-platform or native app

A real app gives the best performance, full device access (camera, location, background tasks, payments through the stores) and the strongest store listing.

• Cross-platform: Flutter or React Native build Android and iOS apps from one codebase.
• Native: Kotlin with Android Studio, and Swift with Xcode on a Mac.

Your website's data then reaches the app through an API. If your site runs on WordPress, its REST API can feed a simple app; a custom site needs its own API. Backend APIs for mobile apps explains the options. This route costs the most in development time and needs ongoing updates for new Android and iOS versions.

7. Publishing to the stores

Store rules and fees change; check the current Play Console and App Store Connect requirements when you start.

8. Which option should you choose?

9. Running the website side on Domain India

Whichever option you choose, the website behind it is what matters, and it can run on any Domain India hosting:

• HTTPS: PWAs and service workers need HTTPS. Domain India hosting includes free SSL certificates.
• The .well-known files: upload assetlinks.json, the manifest and icons with the control panel's File Manager. See How do I use the File Manager.
• An API for a native app: a Node.js backend can run on the App Platform, where Node.js is detected automatically and other languages deploy with a Dockerfile. App Platform: getting started shows how.
• No website yet? The AI Website Builder creates a website you can check in a live mobile preview before you publish.
