Rakuten TV is the official app from the streaming platform for movies and series. It's a subscription-based service, though, so you'll need to pay a monthly fee in order to access all the content it hosts.
Rakuten TV-s content includes thousands of different movies and series, including both must-see classics for film buffs and the latest releases. You can access most of the content by paying the monthly fee, but the latest movie releases typically cost a little extra to rent.
The app is fully compatible with Chromecast, so you can cast whatever you're watching on your device to a larger screen. In the app settings, you can even adjust the subtitle size, which may come in handy.
Rakuten TV is an essential app for anyone with a Rakuten subscription. With this official app, you can enjoy your favorite movies and series whenever and wherever you want.
