App vs. website: The key differences for your business
Whether you should turn your website into an app depends on your industry and whether your product needs custom native interactions. Either way, converting a website into an app is a real path, not a workaround. With a web-to-app tool like Median, your site remains the source of truth; the app shell adds what a browser can't (e.g., push notifications, biometrics, offline access, etc.).
Should you turn your website into a mobile app?
If you're asking this question, you're probably one of two people:
You're a developer who's been asked to figure out whether your company's existing website can become an app, and you want to know what that actually involves before you commit engineering time to it.
You're a product marketer who's looking at app store presence as a growth lever and trying to understand what it would take to get there without derailing your entire roadmap.
Both questions point to the same starting fact: converting an existing website into a mobile app is now a standard path, not a workaround.
The tools for doing web-to-app conversion have matured enough that "build vs. convert" is a real decision rather than a euphemism for "build, but cheaper."
Let’s get into it!

What does it mean to turn a website into an app
Turning a website into a mobile app means taking your existing site (the same content, the same backend, the same logic you've already built), and wrapping it in a native app shell that runs on iOS and Android. The app pulls from your live site, so any updates to your website show up in the app without a new app store submission.
This is different from a progressive web app (PWA), which runs in the browser and can be added to the home screen without going through app store distribution at all. It's also different from building a fully native app from scratch, where a development team writes separate iOS and Android codebases that don't share infrastructure with your website.
The conversion category sits between those two and goes by a few names depending on who's talking about it. Developers tend to say “webview app” or “hybrid app,” and marketers and platforms usually say “web to app conversion.” They're describing the same thing.
Why a developer would look into a hybrid app
If you're the developer fielding this request, the honest version of the question isn't "can this be done," because it can. The real question is what you're trading away and what you're not.
You keep your existing backend, your CMS, your authentication, and your APIs. None of that changes. What you gain is access to things a mobile browser can't give you on its own such as push notifications, biometric login through Face ID or fingerprint, camera and GPS access without the permission friction of a browser prompting every session, and offline caching for screens that don't need a live connection to render.
What you give up depends on how the conversion is built.
A basic webview wrapper, the kind you could build yourself with WebView on Android and WKWebView on iOS, gets you an app icon and not much else. It still depends on the same internet connection your website does, and it won't feel meaningfully different from opening the site in a mobile browser.
Fortunately, the category has matured beyond that baseline, and most platforms built for this now handle native navigation patterns, gesture support, and device API access that a raw webview doesn't provide automatically.
The work that actually takes time is everything app stores require, regardless of how the app was built.
Apple's App Store guidelines and Google Play's policies don't grade on a curve for webview-based apps. You still need privacy disclosures, a working app icon and screenshots set, a support URL, and a build that doesn't trip their automated review for things like external link behavior or in app purchase handling if you sell anything through the app.
Tip: Test your deep linking setup with Median’s Deep Linking Validator before you submit, not after. Apple and Google both cache configuration files such as apple-app-site-association and assetlinks.json, so a misconfigured deep link can appear fixed in your testing and then fail in production because the platform serves a stale cached version.
Why a product marketer would look into web-to-app conversion
If you're the marketer evaluating this, the calculation usually starts with a gap you've already noticed. Your site gets traffic, your mobile web conversion is fine but not great, and you suspect that some portion of your audience would engage more often if there were an icon on their home screen instead of a bookmark they forget about.
That instinct holds up reasonably well. Apps create a return path that a website doesn't. A push notification gets noticed in a way a marketing email increasingly doesn't. And an icon on the home screen gets tapped in idle moments, a browser tab never gets opened for.
None of that is unique to native mobile app development, but simply a property of being installed on the device, rather than a choice about how the app was technically built.
Where the web-to-app calculation gets harder is the timeline and cost relative to what you'd get from building native from scratch. A from-scratch native app usually means hiring or contracting iOS and Android specialists, maintaining two codebases that can drift out of sync, and accepting that any new feature gets built twice.
That's the right call when your product genuinely needs custom native interaction, something such as a camera-based AR feature or a complex offline-first data sync that a converted app can't replicate well.
For most product and content-driven businesses, the calculation tilts the other way.
If your core value is already delivered through your website, you probably don't need native level performance on every screen. What you need to figure out is whether you need an app at all, and if you do, whether the fastest path to it is rebuilding what already works or wrapping it.
Key differences between mobile websites and apps
Understanding the key differences between mobile websites and apps is crucial for making an informed choice based on your business needs.
Accessibility
Mobile websites can be reached directly via a web browser, without the need for downloading or installing anything since they reside on a web server.
This means that as long as users have an internet connection and a mobile browser, they can instantly engage with these websites.
Mobile apps require users to download and install them on their devices for each operating system they intend to use. While this may seem less convenient than simply accessing a website, it allows apps to offer a more tailored and integrated experience for the user.
The personalized nature of mobile apps ensures that users receive content and features tailored to their needs, leading to higher engagement and satisfaction.
Mobile apps can also leverage the full capabilities of the devices, such as GPS, push notifications, and offline functionality, providing a richer and more immersive user experience.
Tip: Ensure your mobile website and app are designed to provide easy access, including features like intuitive navigation and quick load times to enhance user experience.
User interaction
Mobile apps outperform mobile websites in user engagement, using sophisticated gestures such as tap, swipe, and pinch to enhance functionality and create a more captivating user experience that facilitates efficient task completion.
Web browser limitations can restrict the capabilities of mobile websites. Although they can mimic certain app features, they usually don’t deliver as seamless or compelling an experience.
Tip: Enhance user interaction on your mobile app by integrating intuitive gestures and animations. These elements make navigation more engaging and responsive, encouraging users to spend more time on your app.
Cost and maintenance
Financially, while mobile websites are initially more cost-effective, investing in a mobile app can offer superior long-term benefits.
Apps require resources for development and maintenance but provide a personalized user experience, offline functionality, and device-specific features that boost engagement and customer loyalty long-term.
This ongoing investment should be seen as crucial for delivering a top-notch user experience. Businesses should weigh these advantages when deciding between a mobile website and an app.
Tip: Budget for both initial development and ongoing maintenance of your mobile app to ensure long-term performance and user satisfaction.
Which industries benefit most from a mobile app
Retail and e-commerce – Push notifications for cart abandonment and restock alerts usually outperform email on open rate and adding biometric login removes friction at checkout, which matters more for repeat purchase behavior than for first-time conversion. WTSO.com, a long running wine e-commerce business, shipped an app that kept its existing state-by-state compliance logic intact and added push through Cordial without rebuilding the backend that already handled that complexity.
Local service businesses – Bars, restaurants, salons, and similar businesses benefit from the home screen presence more than from any specific native feature. The win is being remembered, not a complex interaction model. Schedulefly, a scheduling platform built for restaurants, shipped to both app stores in two weeks after noticing that over 90 percent of its 225,000 users were already running the entire product from their phones anyway.
B2B SaaS – This is the category where the calculation most often points away from a customer-facing app and toward internal use cases, like giving field teams or account managers offline access to dashboards they'd otherwise need a stable connection to load. Whole Foods built an internal app called Innerview that gives 91,000-plus store associates shift schedules and company updates, and the team didn't hire a single native iOS or Android developer to do it. They kept building on the Vue.js stack they already had.
Media and content publishers – Offline reading and push notifications for new content matter more than any device-specific feature in this category, since the core product is already content consumption your website handles.
How do I turn my website into an app
The mechanical answer is to connect your existing site to a platform built for this conversion, configure the native features you want (e.g., push notifications, biometrics, deep linking, offline screens, etc.), and submit the resulting build to the App Store and Google Play.
The harder answer is the testing and compliance work that sits around that mechanical step.
You're testing across iOS and Android versions, validating deep links actually route to the right in app screen instead of just opening the website, and making sure your privacy policy and data disclosures match what the app actually does (since both app stores have strict requirements about this matching reality rather than being a generic boilerplate page).
FAQ rebuild, grounded in real questions
Is a web to app conversion the same as a Progressive Web App?
No. A PWA runs entirely in the browser and can be added to the home screen without app store distribution. A converted app goes through the App Store and Google Play, which gives it access to push notifications, biometric APIs, and other device features a PWA can't fully use yet, particularly on iOS.
What's a mobile app?
Mobile apps are software applications that users obtain by downloading from platforms such as Apple’s App Store or Google Play to their devices.
These apps are created specifically for certain operating systems such as iOS, Android, and Windows Phone and reside in the device’s memory. They can often work offline, giving them a clear advantage over mobile websites.
Developed with a variety of programming languages and frameworks designed for particular operating systems, mobile apps can harness the power of the device they’re installed on.
Why do webview apps get rejected from the App Store?
Apple rejects webview apps under Guideline 4.2, Minimum Functionality, when the app does nothing a mobile browser couldn't already do. A wrapper that just loads your site in a window with no native navigation, no offline handling, and/or no push notifications reads as a website with an icon, not an app. Adding genuine native elements on top of the webview, like a native tab bar or working push notifications, is what helps get these apps approved.
Will my app need to be resubmitted every time I update my website?
Not for content and most functional changes, since the mobile app pulls from your live site. You'd need a new submission for changes to native features such as push notification configuration or new permission requests, since those touch the app shell itself rather than the website content.
Do app stores treat webview based apps differently in review?
They review against the same guidelines regardless of how the app was built. What gets flagged is usually thin functionality, an app that's indistinguishable from opening a browser bookmark, or missing privacy disclosures, not the underlying technical approach.
How long does a website to app conversion actually take compared to building native?
A conversion can go from start to app store submission in weeks rather than the months a from scratch native build typically takes, mainly because you're not writing two new codebases or rebuilding backend integrations that already exist.
Why choose Median
Median takes your existing website and wraps it in a native app shell for iOS and Android, with push notifications, biometric login, deep linking, and offline access already built in instead of something your team has to code from scratch. Your site stays the source of truth, so most updates show up in the app without a new app store submission.
That matters most for the two people this post started with. If you’re a developer, you get the native capability without taking on a second codebase to maintain.
