Used to be the best. Now it downloads in a fair amount of time, then says it is going to take an hour+ to aggregate a 9.5 minute youtube video which is a still screen and music. If you cancel the aggregating, you lose it all, and I can find no way to stop it. All this since the companion app requirement although you can go without but the downloading seems to have been capped further then.
I'll find something else now.

Came back a year later and it has improved in time it takes and still tells me it requires a companion app, however, now there is a huge QR code all through the video. Is there a point?
