Sure, you're a pro at booking cabs and swiping right on Tinder, but you can do so much more with your smartphone than just get a ride or a date (and you know, make calls). Here's a list of 12 unexpectedly cool things that the mini-computer in your pocket can do: Work as a sci-fi thermal camera. Seek Thermal gives you the thermal technology that was once only available for the military and other professionals. It's a tiny camera that attaches to your smartphone so you can get a thermal image of anything around you, showing you a temperature snapshot of your environment.

Monitor your heart rate.

You don't need to invest in a Jawbone or a Fitbit to monitor your heart rate. All you have to do is download and fire up the Instant Heart Rate app, place your fingertip over your phone's camera lens for 10 seconds and voila... You'll get a detailed report right on your screen!

Project a cool augmented reality map on the windscreen of your car!

If you're driving in the dark, the rain, fog, or just unfamiliar conditions, download Hudway, enter your destination and put your phone on your dashboard. Your phone will project a GPS-enabled map on your windshield without the need for any extra equipment required.
