Amazon's new Halo health wearable has no screen and a steep hill to climb

Amazon unveiled its first wearable on Thursday and it's not what you think. Instead of a cheap smartwatch with Alexa, the Amazon Halo is a minimal wearable with no screen that's designed to keep your body and your relationships healthy. While the Halo connects to your smartphone, you won't be using it to listen to music or get directions. It doesn't have GPS or Wi-Fi or NFC. It has 50-meter water resistance so you can wear it while swimming and 7-day battery life so it can monitor your sleep at night.
