So i looked inside the app, and you can preview the content that's available.
Smartly, they made sure the app only gives audio through the headphones.

There are 22 movies available, not particularly new ones, although a handful are from the last 12 months. About a third are Israeli movies.

There are also TV series, including some HBO TV shows, Music, audiobooks, and even Daf Yomi in Hebrew and English.

So it's a reasonable collection of content, but nothing fantastic.
