How to Distinguish Safari and WebViews on iOS Devices Using JavaScript?

Detect Safari and WebViews on iOS Devices with JavaScript

Determining whether a website is running within the iPad's Safari browser or inside an application WebView is crucial for tailoring user experiences. This can be achieved through a combination of window.navigator.userAgent and window.navigator.standalone JavaScript properties.

By analyzing the user agent string, we can identify the device as an iOS device. If it's indeed an iOS device, we further check for the presence or absence of window.navigator.standalone to distinguish between different scenarios:

• Browser: The website is running in the Safari browser; standalone is false, and the user agent contains "Safari."
• Standalone: The website is running as a standalone application; standalone is true, and the user agent does not contain "Safari."
• WebView: The website is running within an app's WebView; standalone is false, and the user agent does not contain "Safari."

This JavaScript code provides a complete solution for detecting the iOS environment and differentiating between Safari and WebView modes:

<code class="javascript">var standalone = window.navigator.standalone,
    userAgent = window.navigator.userAgent.toLowerCase(),
    safari = /safari/.test(userAgent),
    ios = /iphone|ipod|ipad/.test(userAgent);

if (ios) {
    if (!standalone && safari) {
        // Browser
    } else if (standalone && !safari) {
        // Standalone
    } else if (!standalone && !safari) {
        // WebView
    }
} else {
    // Not iOS
}</code>

This method allows you to adapt your web application's behavior to different environments, ensuring optimal user experiences. For instance, a navigation bar could be hidden when the app is used in standalone mode, or specific features could be disabled when running within an app's WebView.
