24 New Gadgets Every Parent Needs to See

Peeing on a stick to see your most fertile days may soon be a thing of the past. Ava ($199) is a fertility tracker that analyzes temperature, pulse rate, and seven more biological factors to determine your five most fertile days each month. The wearable, which is only worn at night, looks similar to the Apple Watch, but weighs next to nothing. The beauty of Ava is that it identifies your fertile days on the first day of the cycle, rather than once it is almost over, as many other fertility tracking methods do.
