Just found out about this app and was amazed by the example videos.
Aside from the UI of the app is ugly and there is no saved videos, or folder how to organize the videos that we copy from youtube. I tested several websites, and it works smoothly!

There are many points to improve for the app, as the function is too basic. Otherwise, many people will ask the sustainability. And I hope they improve it fast as they gain traction here.

Good luck with the deals!
