I made an iOS app called "Caption This" that adds real-time captions to videos for Instagram stories.

If you've ever tried to watch Instagram stories in a public space, then you already know the problem I’m trying to solve. The “Caption This” app solves this problem by using speech recognition to automatically add closed-captions to videos.

Instagram stories with captions get more engagement. They're also more accessible to deaf members in your audience.

You can edit the captions in case the speech recognition thinks you meant "ducking". You can also change the font and text/background colors of the captions.

The app is built with React Native. At this point it's about 2/3 React Native and 1/3 native iOS and Objective-C. It's also open source (GPL v3) so you can check out the source too if you're into that kind of thing!
