How Much Does It Cost to Turn a Website Into an App? An Honest Breakdown
Wondering how much it costs to turn a website into an app? Here's an honest breakdown of build vs subscription pricing, the store fees you can't avoid, and what actually drives the total.
The short answer: it depends on the pricing model
There is no single sticker price for turning a website into an app, and anyone who quotes you one number without asking questions is guessing. The cost swings enormously based on how the work is priced and what you actually get.
At the top end, a custom native app built from scratch by an agency is the most expensive route: you're paying developers to design, code, test, and ship two separate apps (iOS and Android), which is why quotes there run into five figures. At the other end, no-code platforms that convert your existing site into an app cost a fraction of that because the heavy engineering is already built and reused across every customer.
So before comparing prices, separate three things: the build cost, the ongoing costs, and the store fees. Bundle them and every quote looks confusing. Break them apart and the real total becomes clear.
One-time build vs monthly subscription: the two models
Most website-to-app services fall into one of two pricing models, and the difference matters more than the headline number. A monthly subscription looks cheap up front, but you pay it forever, and in many cases the moment you stop paying, your app stops updating or stops working entirely. Over two or three years, a modest-looking monthly fee can quietly cost more than a one-time build.
A one-time payment flips that: you pay once for the app, and it's yours. There may be an optional maintenance plan for updates, but continued ownership doesn't depend on a recurring charge. This is the model Transform To APP uses — a single one-time payment across three plans, with maintenance offered as an option rather than a requirement.
When you compare offers, always annualize the subscription over three to five years. That's the only fair way to see which model is actually cheaper for your situation.
The store fees you can't avoid
Whatever platform or agency you use, two fees go straight to Apple and Google and are never included in a builder's price because they simply aren't the builder's to charge.
The Apple Developer Program costs 99 USD per year, billed annually for as long as you want your app on the App Store. A Google Play developer account is a one-time 25 USD fee — you pay it once and the account is yours. Together, that's your unavoidable cost of admission to both stores in year one, and 99 USD per year after that for Apple.
The important detail: these accounts should be registered in your own name. When your app is published under your own Apple and Google developer accounts, you own the store listings, the reviews, the download data, and the relationship with your users. Transform To APP publishes under the client's own accounts, with the client's brand and icon — so nothing is locked behind a middleman.
Ongoing costs beyond the build
The build price is only part of the picture. Apps need upkeep: Apple and Google change their rules, release new OS versions, and periodically require apps to be rebuilt against newer SDKs. Ignore that maintenance and, eventually, your app can be pulled from the store or start crashing on new phones.
Here's where the architecture of the app changes your ongoing cost dramatically. If the app simply wraps your live website inside a native container, then any content you publish on your site appears in the app instantly — no new build, no app-store resubmission, no fee. That kills one of the most common hidden costs: paying someone every time you change a price, add a product, or post an article.
Only genuine native changes — a new push-notification flow, a new widget, a new store requirement — need a rebuild. With Transform To APP those native rebuilds are handled for you, so day-to-day content updates never generate a bill.
What you're actually paying for: native app vs web wrapper
Two apps at the same price can be worth wildly different amounts. The cheapest "website to app" tools produce a thin web wrapper: a basic browser window with your URL loaded inside. It technically installs from the store, but it often feels slow, looks dated, and can't do the things users expect from a real app.
A real native app is different. Transform To APP builds in Swift for iOS and Kotlin for Android — actual native code — and runs your live site inside a high-performance native container connected to a JavaScript bridge. That bridge unlocks native capabilities on every plan: push notifications, offline mode, biometric login, deep links, camera and file access, background audio, native bottom navigation, app shortcuts, widgets, Live Activities, AR product view, and text-to-speech, plus support for ads and in-app purchases.
So when you compare costs, compare capabilities too. A slightly higher price for a genuinely native app can be far better value than a cheap wrapper you'll want to replace within a year.
How to budget and decide
To estimate your real total, add three lines: the build (a one-time fee, or a subscription annualized over the years you expect to run the app), the store fees (25 USD once for Google Play, 99 USD per year for Apple), and any maintenance you choose. That single figure — not the advertised headline — is what you're comparing between providers.
Then ask ownership questions that don't show up on a price tag. Is the app published under my own developer accounts? Do I keep it if I stop paying? Do routine content updates cost extra? Is it a real native app or a web wrapper? The answers often matter more than a few euros of difference.
Because plans and features vary, check the current Transform To APP pricing page for exact figures rather than relying on a number quoted in an article — pricing can change, and the page is always the source of truth.
FAQ
Is there a monthly fee to keep the app running?+
It depends entirely on the provider's model. Subscription services charge every month and often stop your app from updating if you cancel. Transform To APP uses a one-time payment instead, with a maintenance subscription offered only as an option. Separately, Apple charges 99 USD per year for its Developer Program regardless of which builder you use.
Do I need my own Apple and Google developer accounts?+
Yes, and that's a good thing — it means you own your store listings and user relationship. An Apple Developer Program membership is 99 USD per year and a Google Play account is a one-time 25 USD fee. Transform To APP publishes your app under your own accounts, with your brand and icon.
Will I have to resubmit the app every time I update my website?+
No, if the app shows your live site inside a native container. Content you publish online appears in the app immediately, with no rebuild or app-store resubmission. Only native changes — like a new widget or push flow — require a new build, which Transform To APP handles for you.
Why are custom-built apps so much more expensive?+
A custom native app pays developers to design, code, and test two separate apps from zero. No-code platforms reuse a native engine already built and maintained across many customers, so the same native features cost far less. You're paying for shared engineering rather than a bespoke project.
How much does Transform To APP itself cost?+
It's a one-time payment offered across three plans, with an optional maintenance subscription — not a recurring fee to keep the app alive. Because plans and features can change, check the official pricing page for the current, exact figures rather than any number quoted elsewhere.
