8Cups is a smart water bottle that syncs with an app on your mobile phone to track your water intake and remind you to drink more. 8Cups integrated sensors trigger an LED display to remind you drink water on a regular, timed basis. When you drink, the amount is synced to your app so that you can track how much you have ingested and how much you have left to drink that day to meet your water intake goal. Plus you can even earn money for staying hydrated! It doesn’t get any better than that.
