Key takeaways
- Google AI Studio builds web apps (React plus a Node.js server) and native Android apps – there is no iOS export, so the App Store route runs through the deployed web app or a rebuild.
- Give the app a stable home: your own domain or an ai.studio subdomain you never unpublish, plus at least one Cloud Run minimum instance against blank first launches.
- Firebase's default Google login fails in embedded WebViews. On iOS, native Google sign-in is the clean fix; email plus Sign in with Apple is the simple one.
- Prompts, photos and voice sent to Gemini are personal data shared with a third-party AI: ask for explicit permission first and run production on a paid Gemini tier.
- WebViewGold, built by our team, turns the deployed app into an Xcode project with native modules; appsubmitter.io handles signing, App Privacy details and the submission.
Our recommended solution
Turn your Google AI Studio app into a real iOS app with WebViewGold
WebViewGold wraps the Google AI Studio web app you already have in a native Xcode project and adds push notifications, a native offline screen, deep links, a QR scanner and more – the native value reviewers at the App Store look for. Built by our own team, and we submit WebViewGold apps all the time.
Can you convert a Google AI Studio app to an iOS app?
Yes, but not with an export button. Google AI Studio generates full-stack web apps and native Android apps; it has no iOS output. To convert a Google AI Studio app to an iOS app, you deploy the web version, wrap it in a native iOS project with real device features, fix sign-in and AI consent, and submit it from your own Apple Developer account.
That route keeps AI Studio as your editor: you keep prompting in Build mode, the web app keeps running on Cloud Run, and the iOS app adds a native layer on top. A native rebuild in Swift is the alternative when real-time voice, continuous camera use or offline work is the heart of the app. If App Review has already flagged your app for hidden features, start with our Guideline 5.6 guide for AI Studio apps.
Started in Firebase Studio? Google is sunsetting it on March 22, 2027; new workspaces and sign-ups have been disabled since June 22, 2026, and Google points users to Google AI Studio or Google Antigravity. Apps already deployed to Firebase keep running, and Firestore and Authentication are unaffected (Firebase docs), so the steps below apply to your deployed web app as well.
What AI Studio builds – and what each part means on an iPhone
| Part | What AI Studio sets up | Consequence for iOS |
|---|---|---|
| Front end | React by default; Angular is also mentioned | Runs in WKWebView: mobile layout, safe areas, no web-only chrome |
| Server | Node.js; Gemini calls run server-side, so the key is "never exposed in the browser" | The iOS app never needs the key. Re-hosting a ZIP export? Set GEMINI_API_KEY on the server, never in client code |
| Data and login | Firestore and Firebase Authentication with "Sign in with Google" | Google login fails in embedded WebViews – see the sign-in section below |
| Third-party services | Keys such as Stripe stored as server-side secrets | Fine for physical goods and services; AI credits need In-App Purchase |
| Hosting | Cloud Run, with a billing-enabled Google Cloud project or the Starter Tier (up to two services, one region) | Services scale to zero, so a first launch can be slow |
| Address | Optional your-app-name.ai.studio subdomain, first come, first served | Your start URL must stay stable for as long as the app is on sale |
| Code | ZIP download and GitHub sync | Version every release and know exactly what review saw |
| Native output | Kotlin and Jetpack Compose – Android only | Nothing to reuse on iOS |
One more line from the docs matters for an App Store app: when you share an app, its Gemini calls "count toward your usage limits", so every iPhone user spends your quota. Plan for paid usage before launch (Google AI Studio docs).

Four ways to turn your Google AI Studio app into an iOS app
| Route | How it works | Strengths | Trade-offs |
|---|---|---|---|
| WebViewGold wrapper | A ready-made Xcode project loads your deployed URL and adds native modules | AI Studio stays your editor; push, offline screen, scanners and In-App Purchase are configuration; Cloud Builder if you have no Mac | Needs native value for Guideline 4.2 and release discipline after approval |
| Capacitor | The React build is bundled into a native project; the Node.js server stays on Cloud Run | Full control, large plugin ecosystem | Developer work and a native project to maintain; Capacitor's remote server.url is "not intended for use in production" |
| Native Swift rebuild | A SwiftUI app; Gemini through your backend or Firebase AI Logic | Deepest camera, audio and offline integration | A full rebuild; AI Studio no longer edits the iOS app |
| Progressive web app | Users add the site to their Home Screen; web push works since iOS 16.4 | No review, no developer account | No App Store listing or In-App Purchase; AI Studio doesn't document PWA support |
For chat assistants, tutors, image tools and planners – the typical AI Studio app – the wrapper is the pragmatic route, because the product logic already lives in the web app and on the server. If you go native, Firebase AI Logic's Swift SDK keeps the Gemini API key on the server and protects your backend with Firebase App Check (Firebase docs).
What you need before you start
- An Apple Developer Program membership, as an individual or an organization. Apps in regulated fields such as finance or health should come from the legal entity that provides the service (Guideline 5.1.1(ix)).
- A Mac with Xcode – or WebViewGold's Cloud Builder, which configures, builds and uploads the app in your browser.
- A permanent URL. AI Studio's docs don't cover your own domain, but Cloud Run's do: Google recommends a global external Application Load Balancer, Firebase Hosting is another option, and Cloud Run's built-in domain mapping is a preview that Google calls not production-ready (Cloud Run docs). Staying on an ai.studio subdomain? Never unpublish – the subdomain is then released for others to claim.
- Paid Gemini usage. Under the Gemini API terms, prompts sent through unpaid services may be used to improve Google's products and read by human reviewers, and apps offered in the EEA, Switzerland or the UK may only use paid services.
- A privacy policy and a support URL that name Google's Gemini API as a recipient of user content.
- A demo account with email and password and realistic data for App Review.
Steps 1–5: get the AI Studio web app ready for an iPhone
- Deploy and pin the address. Deploy from AI Studio to Cloud Run and decide which URL the app loads. Universal links need an
apple-app-site-associationfile on that domain – one more reason to use your own. - Keep one instance warm. Google documents minimum instances as the fix for latency "when scaling from zero active instances". They are billed while idle, but a blank first screen invites a Guideline 2.1 rejection – see 2.1 for WebView apps.
- Make the React app feel native. Use
viewport-fit=coverwithenv(safe-area-inset-*)padding, keep the prompt field visible above the keyboard, hide web headers and footers when your custom user agent marks the app – keeping any cookie consent you need working, in the app's own style – and open external links in Safari. - Ask before Gemini sees anything. Guideline 5.1.2(i) requires you to "clearly disclose where personal data will be shared with third parties, including with third-party AI, and obtain explicit permission before doing so". Show one screen before the first request: what is sent to Google's Gemini API, why, and a link to your privacy policy. Under 5.1.1(ii), users also need an easy way to withdraw that consent later.
- Add account deletion. If people can create an account, they must be able to start deleting it inside the app (5.1.1(v)). Remove the Firebase user and their Firestore data, stored chats and uploads included, and – if you offer Sign in with Apple – revoke the user's tokens through Apple's REST API, as Apple's account deletion page asks.
Google sign-in in an iOS app: which option holds up in review
Firebase Authentication's default "Sign in with Google" breaks the moment it runs inside WKWebView: since September 30, 2021, Google has answered OAuth requests from embedded WebViews with a disallowed_useragent error (Google Developers Blog). Its OAuth policy is just as clear: a developer "must not direct a Google OAuth 2.0 authorization request to an embedded user-agent under the developer's control" – so faking a different user agent is not a fix. The real options compare like this:
| Option | Google's policy | App Review | Effort |
|---|---|---|---|
Native Google sign-in – Google's Sign-In SDK or ASWebAuthenticationSession – with the credential passed to Firebase Authentication | Compliant | Feels native; add Sign in with Apple for Guideline 4.8 | Custom native code in the Xcode project |
| Email and password plus Sign in with Apple in the app; Google only on the web | Not affected | Simple to review, no 4.8 question | Firebase settings, plus a way back in for existing Google users, such as a password reset to the same email |
Handing the login to Safari (WebViewGold's googlelogin:// prefix does this) | Compliant | Risky: Apple says linking out to the default browser to sign in "provides a poor user experience and isn't appropriate" under Guideline 4 | Low in the app, but the session has to find its way back |
| Google login inside the WebView with a modified user agent | Violates the policy | Sign-in can fail at any time | Don't |
Sign in with Apple is the easy part with WebViewGold: pages on appleid.apple.com are detected and handled automatically. Native Google sign-in is a customization of the Xcode project – one you can build yourself, since you own the code, or have us quote separately. Our Guideline 4.8 guide covers the button rules for Sign in with Apple.
The shortcut from Google AI Studio to the App Store
WebViewGold: your Google AI Studio app, native on iOS
Instead of building native features from scratch, start from WebViewGold. You get ready-made Xcode and Android Studio projects for your website, with native modules you switch on in the configuration:
- Push notificationsOneSignal or Firebase, for real, personal events
- Native offline screenNo browser error pages when the connection drops
- Native splash screenApp-like start instead of a loading web page
- Deep linksLinks open the right screen inside the app
- QR & barcode scannerDevice features the website alone can't offer
- In-app purchasesNative purchase flows where the store requires them
No tool guarantees an approval: Apple still judges what your app offers. Use the native features in your main user journey – our App Specialists review your WebViewGold app before it goes to the App Store.
Steps 6–10: build, test and submit with WebViewGold
- Set up WebViewGold. WebViewGold, made by our team, is a Swift Xcode project: put your URL in
Config.swift, set the custom user agent and switch on the modules an AI app needs – push notifications (OneSignal, Firebase or Pushwoosh) for results that take a while, the native offline screen, Face ID re-login, the native share dialog and file downloader for generated output, and the VisionKit document scanner if users ask Gemini about paperwork. - Write purpose strings. Voice prompts need
NSMicrophoneUsageDescription, photo questionsNSCameraUsageDescription. Guideline 5.1.1(ii) asks that purpose strings "clearly and completely describe your use of the data", so say that recordings or images are analyzed by Gemini. - Connect purchases through StoreKit – see the next section.
- Test through TestFlight on a real iPhone: a fresh install, every sign-in option, the consent screen, a failed Gemini request, Airplane Mode and a launch after hours of idle time.
- Complete App Store Connect: screenshots with real output, App Privacy answers covering prompts, photos, audio and stored chat history, and Notes for Review with the demo account and a sample prompt per AI feature.
Apple counts data as collected when it leaves the device and can be accessed longer than needed to serve the request in real time (App Privacy details) – chat history stored in Firestore clearly is. More on consent and labels in 5.1.2 for WebView apps.
Can you sell AI credits with Stripe in an iOS app?
Not for digital goods. Credits, generations, premium models and longer chats unlock functionality, and Guideline 3.1.1 says that requires In-App Purchase. Credits bought this way "may not expire", so allowances that reset each month fit better into an auto-renewable subscription, and restorable purchases need a restore option.
Stripe, which AI Studio keeps as a server-side secret, stays fine for physical goods and real-world services. External purchase links for digital goods are only allowed in certain storefronts under specific conditions – the Guideline 3.1.1 guide tracks the current rules. WebViewGold's In-App Purchase API (Extended license) lets your web code start purchases and restores; verify each transaction on your server before you add credits in Firestore, and show the reviewer the same prices and paywall your users see.
Rejections AI Studio apps meet on the App Store – and how to avoid them
| Guideline | Typical AI Studio trigger | Prevention |
|---|---|---|
| 4.2 Minimum Functionality | A web chat box in a frame | Native navigation, push, scanning and offline handling around the AI feature – 4.2 for WebView apps |
| 4.3 Spam | A remixed App Gallery project that looks like others | Your own design, icon, copy and use case |
| 4.2.6 | An agency or service submits from its own account | Publish from your own account – 4.2.6 for WebView apps |
| 2.1 App Completeness | Cold starts, quota errors, a login the reviewer can't pass | Minimum instances, paid tier, password demo account |
| 4.8 Login Services | Google as the only login | Sign in with Apple or another equivalent option |
| 5.1.2 Data Use and Sharing | Prompts reach Gemini without consent | Consent screen, privacy policy, App Privacy answers |
| 5.1.1(v) Account deletion | Firebase sign-up without a delete option | In-app deletion – account deletion guide |
| 3.1.1 In-App Purchase | Stripe checkout for credits | StoreKit products |
| 5.6 Developer Code of Conduct | Features that change or fail during review | Release discipline and a paid Gemini tier |
| 1.2 User-Generated Content | Shared generations or multiplayer sessions | Filtering, reporting, blocking and contact details |
Where appsubmitter.io fits in
WebViewGold gives you the native app; appsubmitter.io handles everything from code signing to the conversation with App Review. Our App Specialists set up certificates, provisioning profiles, code signing and a CI/CD pipeline with fastlane and GitHub Actions, GitLab CI, Bitrise, Codemagic or Xcode Cloud. We prepare the store listing with screenshot guidance and the App Privacy details – Gemini data flows included – run an AI-powered pre-submission check with a human review on top, submit the app and handle the communication with App Review.
Everything happens in your own Apple Developer account, where our specialists work as members of your team – the setup Guideline 4.2.6 expects. Your app doesn't have to be finished when you book. Code changes such as native Google sign-in or a consent screen aren't part of the packages; we discuss and quote them upfront. Book the iOS submission or talk it through in a free consultation call. Planning Google Play as well? See how to convert Google AI Studio to an Android app.
Checklist before you submit
- The web app runs on Cloud Run at a URL that won't change, with at least one minimum instance.
- Production Gemini calls use a paid tier, and the API key exists only on the server.
- Google login never loads inside the WebView – it runs natively, or the app offers email and Sign in with Apple instead.
- Sign in with Apple (or another login that meets Guideline 4.8) is offered wherever Google sign-in is.
- A consent screen explains what goes to Google's Gemini API before the first request, and consent can be withdrawn.
- Microphone and camera purpose strings say that recordings or images are analyzed by Gemini.
- AI credits and subscriptions use In-App Purchase and are verified on your server.
- Users can start account deletion in the app, and it removes their Firestore data.
- A TestFlight build on a real iPhone survives a cold start, a failed Gemini request and Airplane Mode.
- Notes for Review contain a demo account and one sample prompt per AI feature.
