Downloader by AFTVnews is a handy app that lets you download files directly onto your Fire Stick and Fire TV devices. Simply enter a URL to download files without opening a webpage. The app also features a built-in browser for downloading files from websites and general web browsing, complete with favorites and bookmarks.
Downloader is especially useful for downloading and side-loading APK files for third-party apps not available on the Amazon Store. Once an APK file is downloaded, the app automatically starts the installation process, eliminating the need to use a separate file manager.
After installation, Downloader offers the option to delete the APK file to free up device space. In short, Downloader makes side-loading apps incredibly convenient.
