A co-worker was just asking about something like this yesterday. Unfortunately, it uses only Apple products, and my co-worker wanted a mix of devices.

No idea how I went this long without knowing this app existed. I've spent plenty of money to tools like Place It and this one is only $4.99 and lives right on your Mac toolbar. They have everything from iPhone 4 through 6+, to watches, to desktops. Score.

There are a number of these floating around, what's good about this one in particular is it looks like it returns you a transparent image so you don't need to settle with whatever backgrounds ones like http://dunnnk.com/ are giving you (not that Dunnnk.com isn't good)

Can you set different backgrounds like in Place-It?
