The app installs from the browser
"alluc app", "alluc android app" and "alluc apk" are searched every month. On Android, open the site in Chrome and choose Add to Home screen; on iPhone, tap share in Safari and choose Add to Home Screen. It installs in two taps with the blue icon, opens full-screen with your list, your country and your episode marks inside it, and updates itself every time you open it. Nothing from APKPure, nothing sideloaded.
The add-on, the API and the key
"alluc addon", "alluc kodi", "alluc api key" and "alluc api key for terrarium tv" are the questions of a generation of media-centre users who pointed their add-ons at the old engine's API. Everything that API answered is on the page now: type the title, open its page, press Watch now, and the licensed services carrying it in your country are listed with a link into each. The Watch now list works inside a television browser and casts from the service's own app, which the devices page explains, and the addresses page tells the story of the 2018 closure the key searches come from.
What the installed app keeps
The list, the viewing country and the episode marks, in the browser the app was installed from; Export from My List carries them to another device.
