I'd advise against watching yourself while you lift. e.g. during a deadlift you want to keep a mostly neutral neck position so trying to watch yourself during it is going to compromise your form.
I mostly just lean my phone against my water bottle. I film pretty much all my working sets of my main lifts.
Interesting - I tend to keep eyes forward and neck in line with back, which I'm now wondering means I maybe have the bar too far forward...maybe time I get the phone/water bottle out :)
