Sometimes drinking more water is all we need to feel energized and brighten our mood. HidrateSpark smart water bottle will keep track of how much you drink and help you meet your daily hydration goal by indicating subtle reminders through an internal glowing light. The bottle works via an Internal sensor which monitors how much water (ml or oz.) you drink throughout the day. The glowing light reminds you when to drink more water and signals that you've met your customizable daily intake goal. The bottle syncs to the app in your IOS or Android Bluetooth device, and integrates with fitness trackers including Fitbit, Apple Watch, Apple Health Kit, Google Fit, Under Armour Record and Nokia/Withings.
