Foaling monitoring apps?

Hi all! Has anyone had any experience with the foaling monitor system FoalApp? I pasted the link below. From what I’ve seen you attach a smartphone to the mare’s halter with a special $50 pouch and download the app on “her” phone and yours. Then pay the $20/week subscription and you can check on her via video (and it will alarm if she lays down).

If you have never heard of this what is your favorite/s method or systems?? Looking for experiences with this or anything similar! Foaling out a mare in Feb and am looking for advice on practical monitoring systems (to be used in conjunction with good old eyeballs and sleep deprivation of course :lol:)!!!

Piggybacking on this thread… Anyone used one of these Nest outdoor security cameras as a foal game camera? There are some great sales going on right now and my mare is due sometime in April.

Oh I hadn’t thought of nest! We have the thermostats and love them
