    Base44 App To Mobile App: What Founders Need To Know

    Taking a Base44 app to a mobile app is a packaging, payments and compliance job — not a rewrite. Here is what changes, what breaks, and how to clear both app stores first time.

    Base44 App To Mobile App: What Founders Need To Know

    Quick answer

    Base44 apps convert to iOS well, but three things must be added before submission: native features so the app passes guideline 4.2, Apple in-app purchases in place of Stripe for digital goods, and proper handling of Base44's authentication in the native app. The build itself is rarely the blocker.

    You built a working product in Base44. It runs in a browser, people use it, and now you want a Base44 app to mobile app path that ends with a real install on the App Store and Google Play. This guide covers what actually changes when a Base44 app becomes a native mobile app: the native app, push notifications, in-app purchases, store listings, review rules, timelines and cost.

    What "Base44 App To Mobile App" Actually Means

    Base44 turns a prompt into a database-backed web project in hours. What it does not create is a signed binary the app stores accept. Apple takes an IPA uploaded to App Store Connect; Google takes an Android App Bundle uploaded to Play Console. Neither store accepts a URL. So the move from a Base44 project to a mobile app is a packaging, integration and compliance job layered on top of the product you already built — not a rewrite of it.

    Most founders assume the hard part is the code. It rarely is. The product logic survives the move almost untouched. The work sits in everything a web project never needed: a native app, push notifications, store-compliant purchases, an app icon and launch screen, privacy declarations, offline states, and a support footprint a reviewer can verify.

    The Gap Between A Web Project And An App Store Build

    Think of it as three layers. Your Base44 build is the product layer. On top sits the native layer — the device features a mobile app is expected to use. Around both sits the store layer: metadata, screenshots, privacy answers, age rating, legal pages. A submission fails when any one of those three is missing, and web-first teams almost always ship the first layer perfectly and the other two not at all.

    We wrote the full pre-flight list in our App Store Readiness For AI-Built Apps guide, and the same twelve gates apply whether you create your project in Base44, Lovable, Replit or anything else on the platform hub.

    Three Paths To A Native Mobile App

    There are only three realistic routes, and the right one depends on how deeply your product touches the device.

    Rebuild the app natively

    Highest fidelity, highest cost. Sensible only when your product depends on camera pipelines, background location, HealthKit or offline-first sync. For most Base44 projects it means throwing away a working product to solve problems you do not have.

    A native iOS app with Wanilla

    Wanilla builds a native iOS app with you, ready for you to submit from your own Apple Developer account, with push notifications, StoreKit purchases, biometrics, deep links and app lifecycle handled natively. You publish from your own account and ship in days, and any change to how the app behaves goes out as a new build that Apple reviews. This is the route we run at Wanilla, and it covers both the iOS app and the Android app from one codebase.

    Publish a progressive web app

    Free, and not on the app stores. Fine as an interim step, useless if you want store discoverability, subscriptions, push notifications or the credibility of a real listing.

    How The Native App Works

    This is not an iframe with a logo on it. It is a native iOS app ready for you to submit from your own Apple Developer account, with native code for the moments where the web cannot reach the device. Authentication, purchases, notifications, file access, haptics and share sheets are handled natively; everything else renders from your existing build. The user never sees a browser, an address bar or a page flicker.

    One rule matters more than any architecture choice: the app Apple reviews must be the app your users get. Any change to what the app does or shows ships as a new build that Apple reviews. Our features index breaks down each native capability individually.

    Native Features Your Base44 App Gains

    None of these are exotic. They are simply invisible from inside a web builder, which is why teams create a beautiful project and then discover the missing pieces on rejection day.

    Push Notifications Are The Highest-Leverage Native Feature

    Push notifications are the single biggest reason to leave the browser. Web push is unreliable on iOS and invisible to most users; native push notifications land on the lock screen and drive the retention curve that makes a subscription business work. Registering for push requires an APNs key on Apple's side and an FCM project on Google's, plus a permission prompt you should trigger after a user has seen value — never on first launch. Read the deeper treatment on the Base44 push notifications page.

    Face ID, Biometrics And Offline Behaviour

    Biometric sign-in is a small change with an outsized effect on daily active use, and a strong signal to a reviewer that this is more than a website. See Face ID login for Base44. Offline handling matters just as much: reviewers test in airplane mode. A blank white screen is an instant rejection under minimum functionality. Cache the last known state, show a friendly offline view, and queue writes. This single fix resolves a large share of first-round rejections for web-derived apps.

    In-App Purchases And Subscriptions

    This is where the most money is won or lost. Anything unlocked inside the app must be sold through In-App Purchase on iOS and Google Play Billing on Android. Apple's commission is 15% for most indie founders under the Small Business Program, and 30% above the threshold.

    Practically, you create products in App Store Connect and Play Console, wire StoreKit and Billing into the native app, then reconcile entitlements back to your Base44 backend so a user who subscribes on an iPhone is also premium on the web and on Android. A receipt layer such as RevenueCat or Adapty handles the plumbing — compare the options on the monetization hub and in our RevenueCat vs Adapty comparison.

    What Happens To Stripe

    Stripe keeps working on your website. Inside the app it does not: a Stripe checkout, or a link that says "subscribe on our site", is a Guideline 3.1.1 rejection. The compliant pattern is Apple in-app purchase for digital access sold inside the app.

    Shipping The iOS App

    You need an Apple Developer Program membership ($99/year) in the name of the entity that will own the app. Company accounts also need a D-U-N-S number, which can take a week to issue, so create that request before you need it. Then: bundle identifier, signing certificates, provisioning, an icon set, a launch screen, App Store Connect metadata, privacy nutrition labels, and a TestFlight build before the real submission. Full walkthrough on building a Base44 app for iOS and App Store submission.

    Shipping The Android App

    Google Play is a separate submission with its own rules. New personal developer accounts must run a 14-day closed test with at least 12 testers before production access unlocks, so start that clock early. You upload an Android App Bundle, complete the Data Safety form, and set content ratings. See Convert to Android and our playbook on how to publish an AI-built app to Google Play. Shipping to both app stores from one codebase is normal; shipping to both without planning the billing differences is not.

    Store Listing And ASO

    Your listing is the conversion step between discovery and install. Title, subtitle, the keyword field, the first two screenshots and the first three lines of description do almost all the work. Measure it objectively before you spend on ads — an ASO score will tell you whether the listing is pulling its weight or quietly leaking installs.

    The Rejections Base44 Founders Hit Most

    Guideline 4.2 — Minimum Functionality

    The build reads as a thin web app: no push, no biometrics, no offline state, browser-style navigation. Fix it by shipping real native features, not by arguing with the reviewer. See Base44 limitations and fixes.

    Guideline 3.1.1 — External Purchases

    Any external payment path for digital goods inside the app. Move it to In-App Purchase.

    Guideline 5.1.1 — Data Collection And Account Deletion

    Sign-up demanded before any value is shown, missing in-app account deletion, or a privacy label that does not match what your backend collects. All three are common in AI-built projects because the web version never had to declare anything.

    Two more show up constantly. Guideline 2.1 catches gated apps submitted with no demo credentials — the reviewer hits a login wall and rejects in minutes, so put working test credentials in the review notes. Guideline 4.3 catches template UI and copy indistinguishable from a dozen other submissions, so differentiate the first screen, the icon and the description.

    Timeline, Cost And Effort

    For a typical Base44 project with auth, a database and a subscription: one to two days to build the native iOS app, half a day for icon, screenshots and metadata, half a day for legal pages and privacy answers, then 24–48 hours in Apple review and up to a few days on Google Play. Fixed costs are $99/year for Apple, a one-off $25 for Google Play, and whatever your subscription tooling charges. Teams that run a readiness pass first are far better prepared for review; teams that submit blind average two to three rounds and lose a fortnight.

    Pre-Submission Checklist

    • The app renders full-screen with safe areas and swipe-back gestures
    • Push notifications register and deliver on a real device
    • All digital purchases route through In-App Purchase or Play Billing
    • Restore purchases works and entitlements sync to your Base44 backend
    • Offline state renders instead of a blank screen
    • Account deletion is reachable inside the app
    • Privacy labels match what your backend actually collects
    • Demo credentials and reviewer notes are filled in
    • Icon, screenshots, subtitle and keyword field are finished, not placeholders
    • Support URL, privacy policy and terms resolve on your domain

    Growth After Launch

    Shipping is not distribution. Once your mobile app is live, growth comes from three levers: store listing optimisation, paid acquisition and word of mouth. Pair that with push notifications that are useful rather than noisy, and a paywall placed after the first moment of value rather than in front of it.

    Frequently Asked Questions

    Can I publish a Base44 app directly to the App Store?

    No. Base44 creates a web project; the app stores require a signed native binary. You need a native iOS app ready for you to submit from your own Apple Developer account.

    Will my Base44 project keep working after launch?

    Yes. Your backend keeps running as normal, and any change to what the app does or shows ships as a new build that Apple reviews.

    Do I need both an iOS app and an Android app?

    No, but most founders launch iOS first for monetization and add the Android app once retention holds. One codebase can produce both.

    Can I keep charging with Stripe?

    Only for purchases made outside the app, such as on your website. Anything unlocked inside the mobile app has to use In-App Purchase or Google Play Billing.

    How long does the whole process take?

    Two to four working days of build and metadata work, plus store review. Most delays come from a missing D-U-N-S number or Google Play's 14-day testing requirement, not from engineering.

    How do I know my app is ready?

    Run the twelve gates in our App Store readiness checklist. If every gate passes, you are well prepared for submission, though Apple reviews and makes the final decision.

    Next Steps

    The distance between a working Base44 project and a live mobile app is shorter than most founders fear and more structured than they expect. It is a packaging job, a payments migration and a compliance pass. Get those three right and you are on both app stores this week.
