FAQ

What is a scrubber?

A Scrubber is a component used for audio or video to choose where in the media the user wants to navigate to.

Why can't I just use a slider?

I tried implementing a slider in my app at first and the problem with a slider is new values will be constantly coming in due to the audio or video playing, and a slider will jerk around while the user is scrubbing. Also a user can't fine tune the exact value on large values. Also also the React Native Slider has a limiting styling and no nice animations.
