The Smart Lid measures liquid intake and provide real-time temp readings. Data is sent to an iOS app via Bluetooth. The app keeps track of hydration levels for daily, weekly, and monthly comparisons. The app also works with Fitbit® and can send data of your hydration levels to your health monitoring system.
The bottle can hold up to 700ml of liquid; no hot liquid for this one, though.
The Smart Lid has a rechargeable battery that takes 3 hours to charge to full capacity. Battery life can last up to 12 days which varies according to usage. The lid and bottle can both be hand-washed with soap and water.
