AppDF file is a ZIP archive with an .appdf extension. This archive must contain the description.xml file with application description (title, description text, category, price, requirements, etc.). This description.xml file contains links to the other files in the archive such as APK file(s), screenshots, promo graphics, video, etc. The main sections of the description.xml file are:

• Category information
• Text description (title, short description, full description, keywords, etc.)
• Images (app icon, screenshots, promo images)
• Videos
• Content rating information
• Availability (country list, etc)
• Price
• Requirements (you can specify supported devices if different from the APK file manifest)
• Testing instructions
• Consent
• Customer support information
• Store-specific section

There are more than 36 alternative Android app stores. All of them have their own audience. Submitting your application to only one store, even if it's the market leader, significantly limits your potential user audience. But submitting an app to all app stores could take you several days, and then you also need to upload each update to every store. AppDF makes submitting your application as easy as uploading one file. You simply create an AppDF file using the HTML5 AppDF Editor and submit the generated AppDF file to all app stores.

1. Create an AppDF file for your application using the AppDF Editor or just follow the specification to create an AppDF file manually
2. Submit your AppDF file to the supporting app stores

AppDF is an open file format. It is not an aggregator. There is no middleman in the process. The app developers work directly with the app stores as before. The only difference is a common file format that makes the whole process easier.
