No package is needed to browse
UpMovies works through a browser for searching titles, reading episode guides and keeping My List. There is no native APK download on this site. Adding a home-screen shortcut does not require an APK file.
A name is not a publisher
App stores and download pages can list products with similar names. Their developer, purpose and feature set may differ. Do not assume that a package labeled UpMovies contains your existing saved list or provides the same catalog. The app guide explains the browser option available here.
Moving from an older app
If an app no longer works, keep a record of the series and episode you reached. Search the production here, save its title and add a checkpoint. You can restore an UpMovies text backup from this website, but backups from unrelated apps use their own formats.
