Both macOS and iOS have excellent built-in support for subtitles. And many video player apps will play a subtitle file for you if you just drop it into the same folder as a movie, or even drag and drop it onto a movie that’s already playing.
But if your hearing is fine, why should you bother with subtitles? I came up with a short list:
- The audio on the movie/TV show is unclear.
- English isn’t your first language, and you appreciate the help.
- You want to watch a movie with the sound low.
- You don’t understand the accents in that British TV drama.
The good news is that subtitles are easy. And the bad news? There is none.
