How to turn your website into an app

There are three honest ways to do it. Two of them take months and an app-store account. The third takes minutes and uses the website you already have. Here is how to pick, and how to ship the fast one today.

The three options, compared

Rebuild it natively

Write a Swift/Kotlin or React Native app that talks to the same backend.

Time: 3–9 months
Cost: Highest — two codebases plus store fees and ongoing review cycles.
Best when: You need deep hardware access: Bluetooth, background location, NFC on iOS, ARKit.
Catch: Every content change now ships through app review.

Wrap it in a shell app

A native container renders your website in a webview and is submitted to the stores.

Time: Days to weeks, plus review
Cost: Moderate — one-off build fee or subscription, plus developer accounts.
Best when: You specifically need a store listing users can search for.
Catch: Apple rejects thin wrappers that add nothing beyond the website (App Store Review Guideline 4.2).

Make the site installable

Add a manifest, a service worker and an install prompt so browsers offer "add to home screen".

Time: Minutes
Cost: Lowest — no second codebase, no store account.
Best when: Your product already is the website and you want repeat visits.
Catch: No store listing unless you also package it later.

The fast route, step by step

1
Serve the site over HTTPS
Browsers only offer installation on secure origins. Almost every host does this already.
2
Add a web app manifest
A manifest.webmanifest file declares the app name, icons, theme colour and display mode so the installed app has a real identity.
3
Register a service worker
A service worker is required for installability and is what lets the app open when the network is slow or offline.
4
Show an install prompt
Capture the browser install event on Android and desktop, and render a guided Add to Home Screen sheet on iOS.
5
Measure installs
Track prompt impressions, accepts and dismissals so you can tune the trigger instead of guessing.

What it looks like per platform

iPhone and iPad

Safari does not show an automatic install banner. The visitor taps Share, then Add to Home Screen. A prompt has to explain that visually, which is what most sites get wrong. Once installed, the app launches full screen with no browser chrome and can receive push notifications (iOS 16.4+).

Android

Chrome fires a beforeinstallprompt event when the site meets the install criteria. You can capture that event and show your own branded prompt at a moment that makes sense instead of relying on Chrome’s mini-infobar.

Desktop

Chrome, Edge and Arc all show an install icon in the address bar and support the same prompt event. Installed sites get their own window, dock/taskbar icon and can be launched without opening a browser first.

Common questions

Can I turn my website into an app without coding?

Yes. Making a site installable needs a web app manifest, a service worker and an install prompt. A tool like InstantPWA adds all three with one script tag, so no rebuild or app-store submission is required.

Does the app work on iPhone?

Yes. iOS supports installed web apps from the home screen, and since iOS 16.4 they can also receive push notifications. iOS has no automatic install banner, so the site must guide the user through Share then Add to Home Screen.

Will it be in the App Store or Google Play?

Not by default. An installable web app is added straight from the browser. If store listings matter, a packaging tool such as PWABuilder can wrap the same site for submission.

How long does it take?

A native rebuild is typically months. A wrapper is days to weeks plus store review. Making the existing site installable takes minutes because nothing about the site itself changes.

Does turning a website into an app slow the site down?

It should not. The install layer is a small script that runs after the page loads; the InstantPWA embed is under 15 KB gzipped and defers all work until the browser is idle.
