FAQ

Q How do these terms relate to each other?

WebView is the core technology for web-to-app conversion, APK is the final product, PWA is an alternative approach, and Hybrid App is the broader architectural category. ToApp uses WebView technology to package websites as APKs, generating a type of hybrid app.

Q Do I need to understand these terms to use ToApp?

No. ToApp is designed so anyone can easily convert a website to an app without any technical background. These terms are for users who want to understand the underlying technology.

Q What's the difference between a WebView app and a PWA?

A WebView app embeds web pages in a native app shell and requires APK installation. A PWA is added to the home screen via the browser without installation. ToApp generates WebView apps that provide a more complete native experience (custom icon, navigation bar, splash screen, etc.).
