What you're actually building
Creating an app from a website means wrapping your existing web content in a container that runs on phones and tablets. You are not rewriting your website — you are packaging it so it works like a native app, with an icon on the home screen and the ability to work offline or send notifications.
The simplest approach is a web wrapper: a thin layer that loads your website inside an app shell. More involved approaches involve progressive web apps (PWAs), which add offline functionality and installation directly from the browser, or hybrid frameworks like React Native or Flutter, which let you write once and deploy to both iOS and Android. The route you choose depends on whether you want a quick launch, native performance, offline capability, or all three — because you cannot have all three without significant work.
Key Takeaways
- A web wrapper is the fastest path: it packages your website in an app shell and launches in weeks, but performs like a website inside an app.
- Progressive web apps (PWAs) add offline functionality and home-screen installation without requiring app store submission, and work on both iOS and Android.
- Hybrid frameworks like React Native let you write code once and deploy to both platforms, but require learning a new framework and more development time.
- App store submission (iOS App Store or Google Play) takes one to two weeks per platform and requires annual fees, code signing, and privacy policies.
- Your website's backend does not change — the app simply displays your existing pages in a mobile-optimized container.
Web wrappers: the fastest route
A web wrapper loads your website inside a native app container. Tools like Capacitor (made by Ionic), Cordova, or WebView Studio take your website's URL and package it as an iOS or Android app. The user sees an icon on their home screen, taps it, and your website loads in a full-screen browser window.
The advantage is speed: you can have a working app in two to four weeks. You do not rewrite anything. Your website's performance, design, and functionality stay exactly the same. The disadvantage is that it performs like a website — scrolling may feel slightly less smooth than a native app, and offline functionality requires extra setup.
Capacitor is the most common choice because it integrates with existing web frameworks (React, Vue, Angular) and handles the packaging for you. You point it at your website's domain, configure app icons and splash screens, and submit to the app stores. The cost is usually under $500 if you do it yourself, or $2,000 to $5,000 if you hire a developer.
Progressive web apps: no app store required
A progressive web app (PWA) is a website that behaves like an app without needing to be installed from an app store. Users visit your website in a browser, see an "Add to Home Screen" prompt, and your site appears as an icon on their phone. Tapping it opens your site in full-screen mode, and it works offline if you set up service workers.
PWAs work on both iOS and Android without separate builds. They update automatically when you update your website, so you never deal with app store review processes. The trade-off is that iOS PWAs have fewer capabilities than native apps — they cannot send push notifications or access certain hardware features — and some users do not know they can install them.
Building a PWA requires adding a manifest file (a JSON file that tells the browser your app's name, icons, and colors) and a service worker (a script that caches pages for offline use). If your website already uses a modern framework like React or Vue, tools like Workbox automate most of this. The cost is usually $1,000 to $3,000 for a developer to set up, or free if you do it yourself with documentation.
Hybrid frameworks: write once, deploy everywhere
React Native and Flutter let you write app code once and deploy to both iOS and Android. Instead of wrapping a website, you write in JavaScript (React Native) or Dart (Flutter), and the framework converts your code to native components. The result performs like a true native app and can access phone features like the camera, location, and notifications.
The cost is higher: you need developers experienced in React Native or Flutter, and development takes three to six months for a basic app. You are also maintaining two codebases (web and app) unless you share significant code. This approach makes sense if you need native performance, offline-first functionality, or access to phone hardware.
React Native is more mature and has a larger community, but Flutter is faster to develop in and produces smoother animations. Both require learning a new framework if your team only knows web development. If your website is already built in React, React Native lets you reuse some components and logic, cutting development time.
Submitting to app stores
Whether you use a web wrapper, hybrid framework, or PWA, iOS and Android have different submission processes. Google Play (Android) is faster and cheaper: $25 one-time fee, review takes one to three days, and you can push updates immediately. Apple App Store costs $99 per year, review takes three to seven days, and you must resubmit every time you update your app.
Both stores require a privacy policy, terms of service, and screenshots. Apple requires code signing (a certificate that proves you built the app) and may reject your app if it is too similar to a website or if it duplicates functionality already in Safari. Google is more permissive but may reject apps that are purely promotional or contain misleading descriptions.
PWAs skip app store submission entirely — users install directly from your website — but they reach fewer users because most people do not know the feature exists. Web wrappers and hybrid apps must go through both stores if you want to reach both platforms.
Comparing the three approaches
Each method trades off speed, cost, and performance differently. A web wrapper gets you to market fastest but performs like a website. A PWA avoids app stores but reaches fewer users. A hybrid framework delivers native performance but costs significantly more and takes longer to build.
| Approach | Development Time | Cost | Performance | Offline Support | App Store Required |
|---|---|---|---|---|---|
| Web Wrapper | 2–4 weeks | $500–$5,000 | Website-like | Requires extra setup | Yes |
| Progressive Web App | 2–4 weeks | $1,000–$3,000 | Website-like | Built-in | No |
| React Native / Flutter | 3–6 months | $15,000–$50,000 | Native | Built-in | Yes |
Choose a web wrapper if you need something fast and your website already performs well on mobile. Choose a PWA if you want to avoid app store fees and do not need push notifications. Choose React Native or Flutter if you need native performance, offline-first design, or access to phone hardware like the camera or GPS.
What happens to your website
Your website does not change. The app simply displays it in a mobile container. If you update your website, the app shows the updated version the next time the user opens it (unless you are using a web wrapper with aggressive caching). This means you maintain one codebase instead of two.
The downside is that your app is only as fast as your website. If your website takes five seconds to load, your app takes five seconds to load. If your website has performance problems, your app inherits them. Before building an app, optimize your website's speed — compress images, minimize JavaScript, and use a content delivery network (CDN) to serve assets from servers near your users.
You also need to ensure your website is mobile-responsive. If it is not, the app will be unusable on phones. Test your website on actual phones before wrapping it, not just in a browser's mobile view. A responsive design is not optional — it determines whether your app is usable.
Frequently Asked Questions
Can I make an app without rewriting my website?
Yes. A web wrapper or PWA packages your existing website as-is. You do not rewrite anything. The app loads your website's URL and displays it in a full-screen container. If you want native performance or access to phone hardware, you will need to rewrite parts of your code in React Native or Flutter.
Do I need to submit my app to the App Store?
Only if you want users to find it there. PWAs skip app stores entirely — users install from your website. Web wrappers and hybrid apps must go through the App Store or Google Play if you want broad distribution. App Store submission takes one to two weeks and costs $99 per year for iOS, $25 one-time for Android.
Will my app work offline?
Web wrappers do not work offline by default — they need a service worker to cache pages. PWAs include offline support if you set them up correctly. React Native and Flutter apps work offline if you build offline functionality into them. If offline is critical, PWA or hybrid frameworks are better choices than a basic web wrapper.
How much does it cost to build an app from my website?
A web wrapper costs $500 to $5,000 depending on whether you do it yourself or hire help. A PWA costs $1,000 to $3,000. React Native or Flutter costs $15,000 to $50,000 because you are building a new app, not wrapping an existing website. Add $99 per year for iOS App Store fees.
What if my website is built in WordPress or Shopify?
You can still wrap it. Tools like Capacitor work with any website, regardless of how it was built. Point the wrapper at your WordPress or Shopify domain, and it packages your site as an app. The app will perform like your website — if your WordPress site is slow, the app will be slow. Optimize your site first.
