A smart water bottle is a high-tech container designed to help users stay hydrated. It often features built-in sensors that track water intake and remind users to drink more water throughout the day. Many models connect to smartphones via Bluetooth, allowing users to monitor their hydration goals through an app. These bottles may also include additional features such as temperature control, LED lights that indicate hydration levels, and even integration with fitness trackers like Fitbit or Apple Watch. Smart water bottles aim to promote healthier habits by making hydration more engaging and easier to manage.
