How to Turn Your SITE123 Website Into a Mobile App (Without a Developer)
SITE123 has no App Store export. Here's how to turn your SITE123 website into a branded mobile app and publish it to the App Store and Google Play — no developer needed.

SITE123 builds clean, mobile-responsive websites in minutes. But a SITE123 mobile app — something your customers download from the App Store and keep on their home screen — is a different product, and SITE123 doesn't offer one.
The gap is real, and bridgeable. Here's exactly how to get your SITE123 site onto the App Store and Google Play without rebuilding anything, and what you need to check before you start.
Why a SITE123 Website Is Already Most of the Way to a Mobile App
SITE123's templates are mobile-responsive by design, and the platform generates clean, fast-loading HTML. That matters because the most common failure point for WebView apps is poor mobile performance — and SITE123 sites don't have that problem.
A WebView app works by packaging your existing website URL inside a native app container. The app opens your SITE123 site in a frame that looks and behaves like a native app — no browser bar, no back button, just your site with your icon on the user's home screen. What you built in SITE123 stays exactly as it is. The app is the delivery vehicle.
This is different from rebuilding your site from scratch in a native app framework. It's closer to putting your SITE123 site in a box, labeling it with your brand, and shipping it to the App Store. Any changes you make in SITE123 are live in the app immediately — no resubmission needed.
What You Need to Prepare Before Submitting a SITE123 App
Not every SITE123 setup is ready to submit out of the box. There are three things to check before going anywhere near Xcode or the Google Play Console.
Custom domain. This is the most common blocker for SITE123 apps. Apple's App Store requires apps to load from a legitimate custom domain — not a free SITE123 subdomain like yourbusiness.site123.me. If you're on a free or basic SITE123 plan, you'll need to connect a custom domain first. SITE123 supports custom domains on its paid plans, and the upgrade is worth doing before any app work starts.
Digital products and subscriptions. If you sell digital downloads, online courses, or paid membership access through SITE123, you'll need to address Apple's in-app purchase rule (Guideline 3.1.1). Apple requires that iOS users purchase digital content through Apple's payment system, which charges a 30% commission. The standard fix used by thousands of platforms — including Udemy and Coursera — is redirecting digital purchase flows to a browser tab, where users complete the transaction on your website outside the app. Physical products like merchandise, food, or handmade goods are exempt from this rule.
Pop-ups and consent banners. Some SITE123 sites use cookie consent pop-ups or email subscription overlays that can block the screen on small devices. Test your site in a mobile browser first. If a pop-up covers the content or isn't easily dismissed, either remove it for the app version or adjust its timing and positioning.
The App Store and Google Play Submission Process
Getting a SITE123 mobile app live on both stores requires two developer accounts: an Apple Developer account ($99/year) and a Google Play developer account ($25 one-time fee). Both are registered under your name or business name — you own the listing.
Once accounts are set up, the app binary (an .ipa file for iOS, .aab for Android) goes through each store's review process. Apple's review is manual and typically takes 24–48 hours. Google Play's is automated and usually resolves within hours to a business day.
The most common rejection triggers are preventable: a missing custom domain, thin content, and IAP compliance failures on digital goods. If you've addressed those three points, approval is predictable.
Services like Webvify handle the full submission end-to-end — they build the app from your SITE123 URL, configure push notifications, handle the compliance requirements, and submit to both stores under your developer accounts. If you'd rather do it yourself, our App Store submission guide walks through every step.
What You Get That Your SITE123 Website Can't Provide
Your SITE123 site already handles content and transactions. A SITE123 mobile app adds three things it can't.
Push notifications. You can message users directly on their lock screen — new arrivals, limited-time offers, appointment reminders, event announcements. Push notifications see 60–90% open rates. Email averages 20–30%. For any business that relies on repeat visits or re-engagement, that gap is significant.
Home screen presence. Your app icon sits next to the apps your customers open daily. That passive visibility is impossible to achieve through a website alone. It's not just branding — it's familiarity that drives repeat visits.
App Store discoverability. Users searching for businesses in your category on the App Store can find your app. A SITE123 website has no App Store presence. A published app does.
For a SITE123 site that mostly functions as a portfolio or brochure, the push notification benefit alone is usually enough to justify the conversion. For a SITE123 store or booking site, all three benefits apply.
What the Timeline Looks Like
The conversion from SITE123 to mobile app takes 3–7 business days in most cases, assuming your developer accounts are already set up. If you're creating accounts for the first time, add another 1–2 days.
The app build — wrapping your SITE123 site into a native container — takes a few hours. From there, you're in the App Store and Google Play review queues: Apple at 24–48 hours, Google typically same-day.

Frequently Asked Questions
Does SITE123 let you publish your site as a mobile app?
SITE123 doesn't provide a built-in way to publish your website as a standalone branded app on the App Store or Google Play. Their platform builds mobile-responsive websites, but the App Store requires a native binary — not a web URL. To get an app under your brand name, you need to package your SITE123 site using a WebView wrapper tool or service.
Will a SITE123 app need to be updated separately from my website?
No. Because the app loads your live SITE123 domain, any content changes you make in SITE123 — product updates, pricing changes, new pages — appear in the app automatically. You only need to submit an update to the stores if you change the app's icon, splash screen, or core technical configuration.
How much does it cost to publish a SITE123 app?
The developer accounts alone cost $99/year for Apple and $25 one-time for Google. Beyond that, you'll pay for the WebView app build — either a one-time fee or a subscription depending on the service. If you're on SITE123's free plan, you'll also need to upgrade to a paid plan that includes a custom domain. Total first-year costs for a managed end-to-end service typically run $300–$700 depending on the provider.
