There are two kinds of people in this world -- those who love Krispy Kreme doughnuts, and those who are wrong. For those in the former group, there's now a "Hot Light" app for Android. Using sophisticated doughnut technology, it triangulates your position relative to nearby Krispy Kreme eateries and then notifies you whether the "Hot Now" sign is on -- and it'll alert when you the switch is thrown.
It is simultaneously the most happy (for when that sweet, sweet notification comes in) and sad (light no blinky) Android app we've ever used.
We've got download links after the break.
