We've got scores of electronic gadgets and apps to help us keep track of our fitness — but there's few things you can do as beneficial to your health as quitting smoking. So where's the app for that? The Quitbit Lighter has your answer. This rechargeable lighter uses a heating element to light up your smoke, keeping track of every time you do, and displaying that information on the built-in display and in the companion app that syncs over Bluetooth and can let you see when you smoke, how much you smoke, and lets you view trends over time. It might be the smartest purchase you make all year.
