I have tried over the years a fair number of apps claiming to do what this app does. Those apps fell short of this app performance. This app has given me the tool to use that does its job extremely well in a difficult environment. It bridges a big gap in a need to move from being bound to a site on the internet to allow an indivdual an option of offline viewing in an organized way as it suits a person individual needs. This app’s creator has shown a desire and ability to update as needed to maintain this app function in response to Youtube changes. My experience has been positive responding to my concerns by this app’s creator. Who has to response to a changing programming environment that he doesn’t control so there will be glitches in performance. The alternative to these glitches is not having this service. I am a former system programmer. You the users will determine that outcome. Me, I can highly recommend this app to you. 😎
