Cost to Convert a Website into a True Native iOS App
What it really costs to turn a website into a native iOS app, why a genuine app is not a wrapped website, and how to scope it.
Short answer
Converting a website into a true native iOS app typically costs 20,000 to 80,000 dollars, because a real app is not a wrapped website, it is a native experience built for the phone. A cheap webview wrapper exists but risks App Store rejection and feels second-rate. The price depends on how much of the site becomes native, what the app adds beyond the web, and the backend it reuses. For the general cost picture, see our guide on how much it costs to build an app.
Why a native app is more than a wrapped website
The cheapest way to turn a website into an app is to wrap it: put the website inside a webview, a browser with no address bar, and ship that as an app. It sounds like a shortcut, and it is, but it produces a poor result for two reasons.
First, Apple often rejects it. The App Store Review Guidelines look for apps that offer genuine native value, not just a website in a shell, and a thin wrapper with nothing native is a common cause of rejection. Second, users can tell. A wrapped website feels slow, scrolls oddly, and lacks the smoothness, gestures, and instant response of a real app. It sits in the uncanny valley between a website and an app, doing neither well, and users who expected a real app notice the difference within seconds of opening it.
A true native app is a different thing. A phone is not a small browser; it is a device with gestures, offline capability, push notifications, and hardware features. A real conversion rebuilds the experience natively for the phone, following Apple’s Human Interface Guidelines so it feels right, while reusing your existing backend and data. That is where the cost, and the value, lives.
What you reuse, and what you rebuild
Conversion is cheaper than building from scratch because you reuse part of what you have. Knowing which part is key to the cost:
| Layer | Reuse or rebuild | Why |
|---|---|---|
| Backend and API | Reuse, if clean | The app connects to the same server |
| Database and data | Reuse | Same data, new front end |
| Business logic on the server | Reuse | Lives in the backend, not the app |
| Front-end screens | Rebuild natively | A browser layout is not an app layout |
| Interactions and navigation | Rebuild natively | The phone has its own conventions |
The headline is that the backend is the big reuse and the front end is the rebuild. If your website already has a clean API and database, the app connects to them and you save significant work. If your site is a tangle with no clear backend, part of that has to be sorted out first, which raises the cost. So the honest first question in a conversion is: how reusable is your existing backend?
What drives the conversion cost
Three things move the price of a website-to-app conversion:
- How much of the site becomes native. Converting the core flows is cheaper than recreating every page and feature. Often the app should deliberately do less than the website, focused only on what people actually do on a phone rather than at a desk.
- What the app adds beyond the web. Push notifications, offline support, and device features are why an app is worth having, but each is new native work the website never had.
- The state of your backend. A clean, API-driven backend is a big reuse; a messy one is a cost to untangle before the app can connect.
This is why conversions vary so widely in price. A focused native app over a clean backend is far cheaper than a full recreation over a backend that needs untangling and rebuilding before the app can even connect to it.
Cost by approach
| Approach | Rough cost | What you get |
|---|---|---|
| Webview wrapper | 3,000 to 10,000 | The website in a shell; rejection risk |
| Focused native app | 20,000 to 45,000 | Core flows rebuilt natively, clean feel |
| Full native app | 45,000 to 80,000+ | Full experience, offline, notifications, features |
Two notes. The wrapper is cheap but a false economy for a serious product, because a rejection or a second-rate experience costs more than the saving. And the focused native app is usually the sweet spot: it delivers a real app at a sensible price by doing the core of the website well rather than everything.
The smart approach: convert the core, add native value
The best conversions are not a page-for-page copy of the website. They rethink what belongs on a phone:
- Convert the core flows. The things people actually do on mobile, done natively and well, rather than every page the website has.
- Reuse the backend. Connect the app to your existing API and data, in native Swift, so you build the front end, not the whole system again.
- Add what only an app can do. Push notifications, offline access, and device features, the reasons to have an app at all.
- Cut what does not fit a phone. Not every website feature belongs in the app; a focused app beats a bloated one.
This approach gives a real, fast native app for a sensible cost, and it launches on the App Store cleanly because it offers genuine native value rather than a wrapped page. Publishing it needs the Apple Developer Program account and passing Apple’s review.
The hidden costs of the cheap wrapper
The webview wrapper deserves a closer look, because its low price hides real costs that arrive later. The first is rejection risk: Apple’s reviewers are experienced at spotting an app that is just a website with nothing native, and a rejection means lost time and a rebuild, which erases the saving. The second is the user experience: a wrapper feels sluggish, handles gestures poorly, and lacks offline behaviour, so reviews suffer and users delete it. The third is that a wrapper cannot easily add the native features, notifications, offline, device access, that justify having an app, so you end up rebuilding natively anyway to get them.
Added together, the wrapper often costs more than a focused native app over the life of the product, not less. It is the classic false economy: cheap on the quote, expensive in rejections, poor reviews, and the eventual proper build. For a throwaway or internal tool a wrapper can be fine, but for a product you want users to keep and rate well, it rarely is.
How long a conversion takes
A focused native conversion over a clean, reusable backend typically takes 8 to 14 weeks from design to App Store, similar to building a fresh MVP, because the front end is new even though the backend is reused. A full conversion with offline support, notifications, and many native features runs longer, 4 to 6 months. The single biggest variable in the timeline is the state of your backend: a clean, API-driven backend lets the app team move fast, while a backend that has to be untangled or partly rebuilt first can add weeks before the app work even starts. This is why an honest look at your existing system is the first step in scoping a conversion, and why two conversions of similar-looking websites can differ substantially in both time and cost. A short technical review of your backend before quoting saves everyone from a surprise later, because the app team can see exactly what it will connect to and what it will have to work around, and price the work on evidence rather than a guess.
When you might not need an app at all
Be honest about whether you need a native app before paying to convert. A good responsive mobile website is enough for occasional, browse-style use, and if you already have one, it costs nothing more. A native app earns its cost when you genuinely need push notifications, offline use, device features, better performance, or a presence on the App Store where users look for apps. If none of those clearly applies, improving the mobile website may serve you better and cheaper than converting it, and a good partner will tell you so rather than sell you an app you do not need.
When a native app does make sense, what you buy is a fast, native experience your users prefer to a browser, built on the backend you already have. A team that designs and builds under one roof, as we do, converts the core of your site into a real native app and reuses what you have rather than rebuilding it.

FAQ
How much does it cost to convert a website into an iOS app?
Converting a website into a true native iOS app typically costs 20,000 to 80,000 dollars, depending on how much of the site becomes native and what the app adds. A basic native app covering the core of the site sits at the low end; a full app with offline support, notifications, and native features sits higher. A cheap webview wrapper costs less but risks rejection and feels second-rate.
Can I just wrap my website in an app?
You can technically wrap a website in a webview, but Apple often rejects apps that are just a website in a shell with no native value, and users can tell. A wrapper feels slow and out of place, with none of the smoothness of a real app. For a serious product, a true native conversion is worth the difference, because a rejected or second-rate app costs more in the end.
Why is a native app more than a wrapped website?
Because a phone is not a small browser. A native app has smooth navigation, gestures, offline support, push notifications, and access to device features, none of which a wrapped website has. It follows the platform's conventions so it feels right. Converting properly means rebuilding the experience natively, reusing your backend and data, not embedding the website in a shell.
What can I reuse from my website when building the app?
Usually the backend and the data. If your website already has an API and a database, the app can connect to the same backend, which saves significant work, that is the biggest reuse. The front end, the actual screens and interactions, is rebuilt natively for the phone. So conversion cost depends heavily on whether your site has a clean, reusable backend.
Do I need a native app at all, or is a good mobile website enough?
It depends. A responsive mobile website is enough for occasional, browse-style use and costs nothing extra if you have it. A native app earns its cost when you need push notifications, offline use, device features, better performance, or a presence on the App Store. Be honest about whether those benefits justify the conversion before committing to it.
