Movie Recommendation App vs JustWatch: The Difference

Free on iPhone

Last updated November 13, 2026

What2Watch AI is a free iPhone recommendation app that starts with your mood and picks what you should watch. JustWatch handles availability. Give JustWatch a title you've already chosen, and it tells you where it's streaming. You can also start with your services on JustWatch.

Two different questions

What2Watch AI answers "What should I watch?" with a suggestion engine. JustWatch answers "Where can I watch this?" with a catalog of streaming availability. JustWatch's About page describes that job: showing where to legally watch movies and TV shows, with filters, tracking and notifications when a title reaches your services.

What2Watch AI does a little of both. It suggests a pick, then lists the US services that carry it.

Which one first?
