You already knew your smartphone could be more awesome with all sorts of apps, but did you know that you can turn your phone into a breathalyzer, metabolism measurer, thermometer, credit card machine, and activity tracker? Here are 5 gadgets that turn your phone into something completely different.
1. Breathometer: Love cocktail hour but live in a city that requires you to drive everywhere you go? Quit risking it and get a portable breathalyzer… that attaches to your phone! No joke. The Breathometer measures your blood alcohol content and shows you what’s what on the app. It even tracks your activity so that you can make sure the proper amount of time passes before you get behind the wheel.
2. Thermodo: This one’s a teeny tiny electrical thermometer for your smartphone that lets you measure the temperature right where you are. Measure the temperature indoors or outdoors and track to see how it drops and rises through the day. This is definitely a gadget for weather nerds and budding meteorologists.
3. Square: If you love handmade products as much as we do, then you’ve likely swiped your credit card through a Square reader at a flea market or craft fair. This gadget makes it easy to accept credit card payments anywhere you go. We really love the flexibility it affords folks who love to make and sell their wares.
