iOS video player app with short skip forward/backward feature I like the feature that YouTube has in their mobile app where you can double-tap the left and right edges of the player and it'll skip ahead slightly in that direction. Netflix has a similar feature that I also like. 

Both the scrubbing feature and the tiny player buttons in the iOS default Videos UI just feel awful in comparison.

Is there an alternative video player that has a similar "do this simple action to nudge the active timestamp in the video a couple seconds" feature? 

I am using an iPhone SE running iOS 12.
You can use VLC for iOS.

The app has host of features (just like the Desktop counterpart). You can simply swipe to skip back/forward.
