We had the chance to cover YONO a while ago here. It is a smart wearable thermometer that measures Basal Body Temperature and helps women trying to conceive make better decisions. YONO is a silicone earpiece that is designed to be worn during the night. It measures and records body temperature data every 5 minutes.
The device gathers data to help women understand their ovulation cycles and predict their fertility window. The device has started shipping after its successful Kickstarter campaign.
