AppForge Studio

Convert any website into a native-ready mobile app • Upload icon & splash screen • Smart offline handling

App Branding

App Package

How it works: Generate a zip containing an offline-capable web app wrapper (HTML/JS/CSS + manifest). The generated app includes automatic offline detection + redirect, your icon & splash screen. Ready to wrap with Capacitor / PWABuilder or use as PWA.

App Name

Short Name (for launcher)

Current saved assets:

No assets uploaded yet

Built-in offline detection: The generated app will show "No Internet" screen automatically & redirect when offline.
⭐ After ZIP generation, you can use Capacitor, Cordova, or simply host as PWA.
