I am new to iPad with an iPad Air 3rd generation running iPadOS and I love it! However, I think the the default video player in the files app in iPadOS is lacking and limited. So, I have gone through many video players lately trying to find the best replacement. I have found that with infuse! It has all the features I need: iPadOS 13 dark mode support, folder sorting and local file system support, touchID locking support, good touch gestures for play/pause, and a nice modern UI all in the free version. And you can get more features in pro version!
