Native features for ChatGPT & Codex apps
Each feature page explains the native part (one setting or one URL call) and the web-app part for your ChatGPT & Codex stack, with a prompt to paste.
Push notificationsBrowser web push on iOS only works for home-screen web apps and most users never see it. As a native app built with WebViewGold, your ChatGPT & Codex app gets the real thing: system push notifications on iOS and Android, sent from your backend, from a dashboard, or scheduled by your own JavaScript.In-app purchasesYour ChatGPT & Codex app probably charges through Stripe. On the web that stays. Inside the iOS app, Apple requires In-App Purchase for digital goods (Guideline 3.1.1), and Google Play Billing applies on Android. WebViewGold handles both through RevenueCat with one URL call from your web app.Google login and Sign in with AppleChatGPT & Codex apps typically use Whatever you built: Supabase, Clerk, Auth.js, Firebase. Email and password login works unchanged inside a WebViewGold app. Google and other OAuth providers block embedded WebViews, and Apple adds a rule of its own. Here is how to make every login method work in the app without changing your auth code.Biometric loginA password field feels like a website. Face ID feels like an app. WebViewGold adds biometric authentication to your ChatGPT & Codex app in two flavors: a simple app lock switched on in the config, or a JavaScript API (
bioauth://) that returns the result to your web app so you can gate exactly the screens you want.QR code and barcode scannerBrowser-based QR scanning in a WebView is slow and permission-hungry. WebViewGold opens the native camera scanner from a link (qrcode:// or barcodescanner://) and hands the result straight back to your ChatGPT & Codex app: a URL is opened automatically, a barcode value lands in a JavaScript variable.GeolocationYour ChatGPT & Codex app already calls navigator.geolocation. Inside a WebViewGold app that call triggers the real system permission dialog, and the position comes from the device GPS instead of a browser approximation. No native code: you only write the purpose string and answer the store questionnaires.AdMob adsWeb ad networks pay little inside apps and often break in WebViews. WebViewGold integrates the native AdMob SDK: a banner below your ChatGPT & Codex app, interstitials after a number of interactions, and rewarded videos you trigger from JavaScript when the user wants extra credits or content.Offline modeReviewers switch on airplane mode. Users ride the subway. A ChatGPT & Codex app that shows a white page offline looks broken; a native offline screen with a retry button looks like an app. WebViewGold gives you three levels of offline support, and the right one depends on your stack (Any web stack generated or edited by ChatGPT/Codex: Next.js, React, Vue, Flask, Express).Deep linksA user taps the magic link from Whatever you built: Supabase, Clerk, Auth.js, Firebase in their email and lands in Safari, logged in on the web but not in the app. Universal Links and App Links fix that: https links to your domain open the ChatGPT & Codex app directly. Here is the complete setup, plus custom scheme links for QR codes and other apps.Native share and hapticsTwo small things make a ChatGPT & Codex app feel native in the first minute: a real share sheet (AirDrop, Messages, WhatsApp, Mail) instead of a copied link, and a subtle vibration when something succeeds. WebViewGold exposes both as URL calls you can wire into existing buttons.File downloads and camera uploadsA plain WebView silently ignores a PDF download and shows a bare file picker. WebViewGold saves images to the camera roll (savethisimage://?url=…), downloads PDFs, audio, ePub and Office files, and opens the native camera or gallery for every <input type="file"> in your ChatGPT & Codex app.In-app ratingRatings decide whether a store listing converts. WebViewGold lets your ChatGPT & Codex app show the native rating dialog (rateapp://) exactly when a user is happy: after a completed order, a finished workout, a saved project. You decide the moment in your web app; the native part is one call.Custom CSS and JavaScriptThe website needs a cookie banner, a footer with 30 links and a "Download our app" badge. The app needs none of them. WebViewGold injects a custom.css and custom.js file into every page your ChatGPT & Codex app loads inside the app, so the website stays untouched and the app looks like an app.NFC tag readerSafari gives websites no NFC access at all, and Web NFC only exists in Chrome on Android. Wrapped with WebViewGold, your ChatGPT & Codex app starts a native NFC scan with one link and receives the tag content in a JavaScript function: on Android through the documented NFC API, on iPhone through the WebViewGold NFC plugin. Check-ins, equipment tags and tap-to-save contact cards become a few lines of code.Document scannerIf your ChatGPT & Codex app has a file upload, it can have a real document scanner. WebViewGold adds a Scan document entry to the native upload dialog: Apple VisionKit on iPhone and Google ML Kit on Android find the page edges, crop and enhance each page, and hand the result to your existing file input like any other upload.Printing and AirPrintThe print button that works in the browser usually goes quiet inside an app, because app WebViews do not handle window.print() the way Safari or Chrome do. WebViewGold gives your ChatGPT & Codex app a native alternative: printitem:// downloads a PDF or image from your server and opens the system print dialog, AirPrint on iPhone and the Android print service, with Save as PDF as an option.Clipboard copy and pasteCopy buttons that silently fail and paste fields that never fill are classic WebView annoyances. In a WebViewGold app, your ChatGPT & Codex app reads the device clipboard on demand with getclipboard:// (the content lands in the clipboarddata variable), and copying uses the standard web Clipboard API with a fallback. Here is the pattern, plus the privacy rules both platforms enforce.Contacts accessFind-your-friends screens, group invites and split-the-bill apps often want the address book. In a WebViewGold app, your ChatGPT & Codex app asks for permission with requestcontactpermission:// and receives names and phone numbers as JSON in the contacts variable after readcontacts://. The code takes minutes; how you use the data decides whether the app passes review.Video and audio playbackAn HTML5 video tag works inside the app, but long lessons feel cramped and playback usually stops when the user switches apps. With WebViewGold your ChatGPT & Codex app hands a stream URL to the native player with one link (startnativevideo://), so viewers get fullscreen and Picture-in-Picture on both platforms and AirPlay on iPhone. On iOS you can also keep HTML audio playing in the background for podcasts, radio and audio courses.Screenshot protectionPaid lessons, private chats, account balances, single-use coupons: some screens should not end up in a group chat. WebViewGold can block screenshots and screen recordings on Android and detect them on iOS, then call a JavaScript function in your ChatGPT & Codex app so you can react. The same toolkit also works the other way round: takescreenshot:// saves a screen to Photos on purpose, for tickets and receipts.HealthKit and Health ConnectFitness trackers, habit apps and coaching tools built with ChatGPT & Codex can show the user's real step count, heart rate or weight instead of asking them to type it in. WebViewGold reads and writes Apple Health (HealthKit) on iOS and Health Connect on Android with the same two URL schemes. The code is the easy part; the store rules for health data deserve most of your attention.Calendar eventsA booking that is not in the user's calendar is a no-show waiting to happen. On iOS, WebViewGold lets users add an event to the Calendar app from a plain link to an .ics file, so your ChatGPT & Codex app needs nothing more than a URL that returns the event. Android has no dedicated calendar API in WebViewGold; here is what works there instead.FlashlightReading a serial number in a dark storeroom, checking a meter in a basement, finding a seat at a concert: sometimes your ChatGPT & Codex app just needs light. WebViewGold switches the phone's torch on and off from two links, enableflashlight:// and disableflashlight://, on iOS and Android. It is a small feature that works best as a helper inside a bigger workflow.Share extensionA bookmarking tool, a recipe box or a moodboard is only useful if saving takes one tap. With WebViewGold your ChatGPT & Codex app appears in the iOS and Android share sheet, and whatever the user shares (a link, a piece of text, a photo) arrives in your web app as the JavaScript variable sharedData. Your code decides what happens next: prefill a form, save it to your backend, or open an editor.Widgets and shortcutsThe home screen is where an app proves it is more than a bookmark. On iOS, WebViewGold gives your ChatGPT & Codex app four ways to live there: an image widget your server keeps current, quick actions on a long press of the icon, Siri phrases that run your JavaScript, and alternate app icons. Android has no WebViewGold equivalent for widgets and quick actions, so this guide also covers the honest alternatives there.Apple Wallet passesIf your ChatGPT & Codex app sells event tickets, runs a loyalty program or hands out coupons, the pass belongs in Apple Wallet, on the lock screen when it matters. WebViewGold adds the missing link: replace https:// with addpkpass:// in your .pkpass URL and iOS shows the native Add to Apple Wallet sheet. You still create and sign the pass yourself, and on Android, Google Wallet works through its own web save link.Native storage and device IDUsers expect an app to remember them. Cookies and localStorage usually keep your ChatGPT & Codex app signed in, but they are web storage and go away with the cache. WebViewGold adds two small native helpers: a persistent value store (writevalue:// and readvalue://) for settings and session restore, and a device UUID (get-uuid://) for device-bound licenses, trusted devices and per-device settings on your server.Meta Audience Network adsIf your audience lives on Facebook and Instagram, Meta Audience Network can be an alternative to AdMob. WebViewGold integrates the native Audience Network SDK: timed or page-triggered interstitials on iOS, banners and interstitials on Android, configured in Config.swift and Config.java and steered from your ChatGPT & Codex app. Here is the setup, the privacy paperwork and where ad apps get rejected.Native tab bar and navigationA hamburger menu and a website header are the fastest way to make a ChatGPT & Codex app feel like a bookmark, and that is exactly what reviewers judge under Guideline 4.2. WebViewGold adds a native tab bar or sidebar on iOS and a Material bottom navigation or drawer on Android, each configured in one file, while your web app keeps doing the routing.Splash screen and loading indicatorA white screen for two seconds after launch is how a ChatGPT & Codex app collects a Guideline 2.1 note or a one-star review. The native app opens instantly; your web app needs a moment. WebViewGold covers that moment with a branded splash, a native loading indicator and pull-to-refresh, and a few lines in your web app make the hand-off invisible.Safe area and status barA ChatGPT & Codex app that looked perfect in the browser can lose its header under the Dynamic Island, its tab bar under the home indicator, or its clock to white-on-white in dark mode. WebViewGold keeps your page inside the safe area by default and colors the status bar natively or from JavaScript. Here is when to rely on that and when to go edge-to-edge with CSS.Force update and version checkYour ChatGPT & Codex web app updates with every publish, but the native shell around it only changes when users install a new store version. When a new feature depends on a newer shell, or old builds point at a URL you are retiring, you need to know who is behind. WebViewGold hands your web app the installed version; a few lines of code turn that into a gentle banner or a hard update screen.External links and URL handlingOn the web, a link to Stripe, Google login, WhatsApp or your help center just works. Inside an app every link needs a destination: the app itself, an in-app browser tab, Safari or Chrome, or another app such as Mail, Phone or WhatsApp. Get it wrong and users end up stranded on a third-party page with no back button, logged in in the wrong place, or paying in a browser while the app waits.ChatGPT & Codex at a glance

Example: from ChatGPT & Codex project to approved app
Say you built a recipe scaler and grocery list app with ChatGPT and Codex: it scales any recipe to the number of guests, and a "What can I cook?" chat suggests dishes from what is in the fridge via the OpenAI API. Codex moved the API call into a serverless function, added a /privacy page and a report button on chat answers, and you deployed the repository to Netlify on your own domain. WebViewGold wraps it, with the share sheet for sending the grocery list to a partner and haptic feedback when items are checked off. A short demo flow in the review notes shows the reviewer how to try the chat without an account. Both stores approve it, and each merged pull request updates the app.
Your first week after launch
- Let Codex pick up bug reports as tasks and review its pull requests; merged and deployed fixes reach the apps immediately.
- Track OpenAI usage daily in launch week and add per-user limits if a few users drive most of the cost.
- Read reported chat answers and tighten the system prompt or the filters.
- Record the WebViewGold bridge calls in AGENTS.md, so future Codex tasks keep them intact.
- Ask for a rating with rateapp:// after a user checks off a complete grocery list.

Frequently asked questions
How do I publish a ChatGPT-built app in the App Store?
Deploy the code to a public HTTPS URL, insert it into WebViewGold for iOS, build with Xcode or the Cloud Builder and submit via App Store Connect. The same URL powers the Android app.
Does Apple accept apps that use the OpenAI API?
Yes, with content moderation, a privacy policy that describes the processing and keys kept on the server. Many WebViewGold apps use AI backends.
Do I need the OpenAI Apps SDK to put my ChatGPT-built app in the App Store?
No. The Apps SDK is for apps that run inside ChatGPT itself. A store app is your own web app on your own URL, wrapped with WebViewGold; it can call the OpenAI API from your server, but it does not need ChatGPT to run.
My ChatGPT Canvas app is a single HTML file. Is that enough for the stores?
Usually not on its own. Host it on a permanent HTTPS URL first, then add what an app needs: several real screens, a privacy page, an offline state and at least one native feature such as push notifications or the share sheet. Codex can turn the file into a small project with those pieces.
