Open the catalogue first
There is no installation step between you and the Cinebloom movie search. Open the homepage in your usual mobile browser and try a title. The menu contains Movies, TV Series and the other main sections; My List keeps the films you save in that browser.
Put Cinebloom within reach
A bookmark is the simplest way back. If your browser offers an Add to Home Screen or similar option, you can use it for a shortcut. The wording depends on the browser and device. A shortcut opens the website; it does not add a separate library of downloaded films.
About Cinebloom APK results
This website does not provide a native Android package. Search results can show newer apps with the same name and different publishers. Check the publisher and the app's function rather than assuming that matching names mean matching services. You do not need one of those apps to use this catalogue.
Moving to another screen
If you save films on your phone, create a list backup before moving to another browser. For video on a TV, use the chosen viewing service's supported app. The catalogue shortcut and the app that plays a film do different jobs.
