The oral thermometer probably didn’t need to be reinvented, but if you’re the kind of person who likes everything to be smartphone-connected, Kinsa’s smart thermometer works with both iOS and Android, and is down to $10 today.

Kinsa markets this as a kids thermometer, mostly because it only takes 10 seconds to get a reading, and its smartphone app includes a little bubble popping minigame that kids can play while they wait, but it’s a neat little gizmo for sick people of any age.

The app automatically tracks your temperature over time, and you can add your own metadata about symptoms and medication if you want a more complete record of your illness. Plus, if you own an iPhone, the temperature data is compatible with Apple’s HealthKit.

Obviously, nobody really needs this thing, but if you’re intrigued, $10 is the best price we’ve ever seen, and is also not a terrible price for a good oral thermometer, smart or otherwise.
