We can’t say with 100% certainty, but we believe what makes Cardiio work is witchcraft. It’s either that or some technology our brains can’t quite wrap around yet. Basically, the five buck app measures your heart rate by you simply looking at your phone. By using your iPhone’s front-facing camera, Cardiio tracks the light reflect off your face and (presumably with black magic) gives you an accurate reading of your heart rate. It also lets you track your fitness level, estimate your potential life expectancy and compare your data to others. For some reason an app that costs $5 seems insanely expensive to us, but this is one that is actually worth the dough.

Unzip your coat and have some mulled wine on the house—you’ve arrived at your final gifting destination: The Holiday Gift Guide. It’s like your friendly neighborhood one-stop holiday shop, except instead of balsa wood ornaments, ours is packed with thoughtful gifts for everyone on your list. Future heirlooms, small-but-significant stocking stuffers, and gear for getting out there (or staying in)—are all right here. There’s no music playing in the background though, so you’ll just have to hum Bing Crosby while you click around instead.
