Apparently you can use Android and iPhones as webcams (e.g. see https://reincubate.com/camo/ ).

have you used these apps before? what's the experience like?

I've tried a few of them on iOS and they have all worked well. Some work over wifi and some over a connected USB cable. I tested these: http://iriun.com (open source, free, works over wifi) https://reincubate.com/camo/ (free, upgrade for more features, works over cable) https://neural.cam/live/ (free, upgrade for more features, works over cable)

I have not, though my coworker does sometimes (Camo) and the video quality is quite good.
