Shaun T is great and the Insanity plus T25 are very motivating. My wife uses them a lot.
We did look at the Apple Fitness one's yesterday and they looked pretty good. We didn't do the free trial yet (she got a new Apple watch for Christmas), but we'll probably do it next weekend. The bits you could see looked good though.
It would be cool if they brought Shaun T on board for Apple too.
i just updated my iOS and went through them too. While the production values and even the workouts themselves look good - I am quite bummed that it does not have a program or a workout calendar kind of an approach. For me one big reason the Shaun T workouts worked was having a 60 or so day calendar to follow. And then switch it up with some other workout.
over the last 5 years or so I and my wife have done workouts of almost everyone on beachbody roster (Shaun T is my favourite) Their workouts are really, really good, and their library is truly massive. If you can keep yourself away from the MUlti-level-marketing stuff their workouts are top grade with pretty good production values. They have a streaming product too, but it does have technical issues I hear. I have their DVDs collected from long time back though.
