HTML to APK Builder

Turn your HTML projects, local files or web sites into the Android apps - without a computer, Android Studio, or build servers. Compiles and signs directly on your device.
Supported imports:

• Single HTML file with embedded CSS and JavaScript
• Folders or ZIP archives with HTML, CSS, JS, images, audio, and custom fonts
• Live URLs or web portals
• Built-in code editor for writing and editing HTML with live preview, syntax highlighting, search and undo/redo
• PDF files (turned into an app with its own reader)

PDF reader and editor:
• Read your PDFs in the built-in library with zoom, bookmarks and night mode
• Edit them too: rotate, delete or move pages, merge files, draw or add text

App properties:
• Set the desired app name, package name, version and Min SDK, with an auto-increment version code toggle for Google Play
• Upload an App Icon (with built-in 1:1 cropper) or generate a unique letter/emoji icon
• Set a custom splash screen, choose background color and screen orientation (Portrait, Landscape, or Auto), request fullscreen or hide the top-bar/notch, use the 'keep-screen-on' mode for kiosks/dashboards/games
• Desktop mode toggle and deep links with custom URL schemes (myapp://)
• Pick status/navigation bar colors and light/dark mode

WebView advanced settings:
• Offline support: bundle HTML, CSS, scripts, images, and other content into the APK
• JavaScript, LocalStorage, SessionStorage, IndexedDB are enabled by default
• Native JS Bridge is available to control hardware: vibration, toasts, flashlight, system dialogs, alarms, sensors, audio recording, files, clipboard and more; call window.AndroidAPI from your web code
• A custom download manager is available: save any file, blob URLs, canvas images, or PDFs
• Pull-to-refresh and back-button history navigation (navigate back before closing the app)
• Hardware permissions: Camera, Microphone (WebRTC calls), GPS, Vibration
• Custom cache modes, User-Agent, a 'No internet' dialog and mixed content support
• AndroidAPI only works on your app's own pages, so ads or other sites can't call it
• window.open popups work, so OAuth logins and payment pages open fine. navigator.share works too

Google AdMob monetization (optional):
• Sticky banners at the top/bottom of WebView
• Interstitials shown on timer or page views counter
• Rewarded video for games and apps.
• Test ads mode (Google demo IDs) to avoid account bans.
• Google UMP consent form for GDPR, plus TFCD/TFUA settings

Signing and publishing:
• 1-click direct installation: launch built APK on your device immediately
• Two build modes: Simple (build an APK in 10 seconds) and Advanced (fully customizable)
• Keystore manager: create or import RSA 2048 .jks (or auto-create one for test builds), sign your APKs, and manage them
• APK signing schemes: v1, v2, and v3 are supported.
• Android App Bundle (.aab) export for Google Play, plus a PEPK export tool for Play App Signing
• Export the entire Gradle + Kotlin code ZIP for editing in Android Studio at any time.

Your projects:
• Organize projects in folders, duplicate them, find old builds and export many at once
• A quality check before building catches missing files; in-app user guide and Google Play publishing guide

App templates:
• All essential templates are included: HTML5 mini-games, device API binders (flashlight, vibration, GPS), and Google AdMob demo app.
• Library templates (React, Vue, Phaser, PyScript and more) and showcase apps, each with an AI prompt for ChatGPT or Claude
• Advanced templates come with Pro

Pro account (optional):
The free version allows you to create and test as you wish. The Pro version is required to export unlimited apps, Google Play AABs, or Android Studio projects. It also includes splash screen support, and no-watermark features and more.

All your data is stored locally on your device. No accounts, analytics, or cloud storage.

Recent changes:
• New app options: Block screenshots, pause sound in the background, or keep your app running off screen.
• Advanced Build: Settings are grouped and explained, and the summary shows every step at a glance.
• Fixes: The Next button stays above the keyboard, and devices without a document picker no longer crash.
