It seems like you're asking about an app or tool that can identify movies based on certain inputs, like a scene or a description. The term "What Movie Is This App?" could refer to several different services, but the most notable among them is likely "Shazam for Movies" or similar movie recognition apps.
These apps typically allow users to identify movies by capturing audio clips or using visual recognition technology. For instance, if you play a movie scene or show a picture from a film, the app analyzes it and provides information about the title, cast, and other relevant details.
In addition to standalone applications, there are also platforms integrated into services like IMDb or Google, where you can search for movies based on keywords, quotes, or images. If you're looking for specific features, such as recognizing quotes or matching scenes, some dedicated movie trivia apps might also fit the bill.
If you can provide a bit more detail about the specific app or service you're referring to, I'd be glad to give you more tailored information!
