Part 1. Why You Need a Caption and Subtitle App

People used to think of captions and subtitles primarily for films or television, but they're now important for all kinds of videos—be it for social media posts, vlogs, educational tutorials, or promotional content. And since people today make videos on their phones, apps that add subtitles and captions on iPhones help make your videos accessible without extensive setup or expertise.

But why should you bother adding captions anyway? There are actually several key benefits when you do this:

  1. Increase Accessibility: Approximately, 20% of the world's population have some degree of hearing loss, which equates to around 1.5 billion people who may struggle to access your content without captions. By including captions, you make your content more inclusive and can be enjoyed by a wider audience.
  2. Easier Viewing Anytime, Anywhere: People often watch videos in places where playing audio isn't practical. Captions let viewers follow along even if they can't turn on the sound—whether in a quiet library, on a noisy bus, or simply prefer to read along. This flexibility makes it easier for your audience to stay engaged.
  3. Boost Engagement and Watch Time: Captions help capture and keep the viewer's attention. Research shows that videos with captions tend to have higher watch times, as they make it easier for people to follow the content. The longer your viewers stay engaged, the better your video performs on social media and search engines.
