A Prince Edward Island, Canada, farmer is using an iPhone app to help him care for his cows.

Derwin Clow had seven cameras installed in his barn in Freetown, east of Summerside, and he can keep an eye on his most valuable assets from pretty much anywhere.

An app on his iPhone allows him to tune into any of the cameras for a live look at his herd.

Clow said he has watched his cows from the movie theatre, from home when he's with his family or even in the middle of the night from bed.

Cows can also get trapped or caught in equipment, meaning frequent checks are important. Farmers also want to know when the animals are going into heat.

"Maybe I'm out on the tractor, or gone to town. I can look at it and see if there's any cows showing heat and then I can use the same phone to call the artificial inseminator and have her bred," Clow said.

Though I don't know Derwin, my family has been friends with the extended Clow family for many years.
