Today at NYU's ITP Spring Show, Katie Bauer is showing off the Ovu fertility tracker. This frilly little armband includes an electronic thermometer powered by a 12-volt battery, which tracks the wearer's body temperature day to day. When a sudden change in temperature signals ovulation, the armband plays a little tune, letting the woman (and apparently anyone else standing nearby) know she's ready for action.
