Tto calculate the amount of water you need each day, a new 'smart' water bottle has been designed. It can be linked with your smart-phone to help you stay hydrated.

The bottle keeps a track of the time and amount of water that has been consumed during the day, and sets off an alert sounds along with a specific LED color code, when its time to have water.
Also, the system can be customized to help a user obtain specific goals.
The glass bottle is dishwasher safe and comes in a rubber sleeve for protection and easier grip if out running, along with a ten-day rechargeable battery.
