Meet the Coaster Talk: a smart coaster that connects to your smartphone via Bluetooth. It tracks and analyzes your water intake. It can also be used to track milk intake for babies. The companion app provides you with a personalized plan to make sure you get the amount of water your body needs. Users can always enter their information manually to change things.
The coaster keeps track of your data for a week and can sync it to your smartphone via Bluetooth. The app puts your data on a graph to help you make better sense of it. The rechargeable battery (250 ma) lasts up to 4 days. The device is water rated at IP65. You can recharge the Coaster Talk using a mini USB cable. The idea certainly sounds interesting as long as people remember to use a device like this. You can find out more information about it on Kickstarter.
