This app has two main functions.

The first is a video player for analyzing videos on Twitter. Since it is difficult to view videos on the Twitter app, we created this function to analyze videos by stopping and fast-forwarding.

The second function is to change the speed of videos on "your" iPhone and save them. If the playback time of a video on Twitter is too long, it may not be uploaded, or the user may get bored with the video. This is a demand to prevent it from happening.
