System share sheet
Navigate to shareapp://message?=Check this out&url=https://app.yourdomain.com/item/42 and the native share dialog opens with your text and link. Users pick the app they want.
What you get
Haptic feedback
Call lighthaptic://, mediumhaptic://, heavyhaptic://, successhaptic://, warninghaptic:// or errorhaptic:// from a hidden iframe or window.location to give tactile feedback on key actions.
Receive shares (Android)
With the ShareIntent API your app can also appear as a share target in other apps and receive text, links or images into your ChatGPT & Codex web app.
Prompt for ChatGPT & Codex
Paste this into ChatGPT & Codex to implement the web-app side. Review the result, publish, then test inside the WebViewGold app.
Prompt for ChatGPT or Codex
Add native share and haptic feedback for the mobile app wrapper. Create lib/native.ts exporting isNativeApp() (navigator.userAgent includes "WebViewGold"), share(text, url) which in the native app sets window.location.href to 'shareapp://message?=' + encodeURIComponent(text) + '&url=' + encodeURIComponent(url) and otherwise uses navigator.share or clipboard copy with a toast, and haptic(kind) mapping light, heavy, success, warning and error to lighthaptic://, heavyhaptic://, successhaptic://, warninghaptic:// and errorhaptic://, queued 300 ms apart. Replace existing share buttons with share(), call haptic('success') after successful mutations, and add an "Invite friends" flow using a server-generated referral code and APP_URL/join?ref=CODE. Add the schemes to AGENTS.md and open a pull request.
Great way of converting your web app to a native app! Fast turn-around, and a great way to get your apps into the app stores without the need to develop a full native app!

Find the share moments
Invite a friend, share a result, send a listing, recommend the app. Each gets a button that calls
shareapp://inside the app and the Web Share API or a copy-link fallback in the browser.Detect the app
Check for the WebViewGold user agent (configurable in Config.swift / Config.java) and only then use the native schemes; otherwise fall back to
navigator.share.Add haptics to confirmations
successhaptic://after a saved form or completed order,errorhaptic://on validation errors,lighthaptic://on toggles. Keep it rare so it stays meaningful.Track shares
Append
?ref=shareto shared URLs so Your own API or serverless functions can attribute sign-ups to sharing.
A share helper for your web app
Works in the app and in the browser:
javascript
function shareItem(text, url) {
var inApp = navigator.userAgent.indexOf("WebViewGold") !== -1;
if (inApp) {
window.location.href = "shareapp://message?=" + encodeURIComponent(text) + "&url=" + encodeURIComponent(url);
} else if (navigator.share) {
navigator.share({ text: text, url: url });
} else {
navigator.clipboard.writeText(url);
}
}
function haptic(kind) {
if (navigator.userAgent.indexOf("WebViewGold") !== -1) { window.location.href = kind + "haptic://"; }
}Frequently asked questions
Does the Web Share API work inside the app?
Partially, depending on the system WebView. The shareapp:// scheme is the reliable way and gives you the full native sheet on both platforms.
Do haptics work on Android?
Yes, the same haptic schemes trigger the vibration motor on Android devices that support it.
Is sharing relevant for App Store review?
It is one of the native capabilities reviewers see; combined with push notifications and offline handling it supports the Guideline 4.2 argument.
Three ways to get your app into the stores
Same result, different amount of work on your side. All three come with the approval guarantee and 24/7 human support.
