The REBO Drink water Save the sea app is designed to help users drink more water and contribute to saving the ocean from plastic waste. With daily reminders, a hydration coach, and a water tracker, this app aims to improve users' health while making a positive impact on the environment.

The app acts as a personal hydration coach, creating a personalized hydration plan based on users' daily physical activity and personal characteristics. Whether you're an athlete, a regular exerciser, or simply someone who walks to work, REBO will calculate your dehydration levels and adjust your water intake target accordingly. By guiding and coaching users, the app ensures they drink the right amount of water to stay healthy and feel better.

One unique feature of REBO is its commitment to environmental sustainability. For every bottle of REBO SMART or REBO GO that users drink, the app funds the collection of a plastic bottle from the oceans. Users can track their plastic savings, the number of plastic bottles collected, and the CO2 emissions avoided through the app.

The REBO water tracker app helps users monitor their daily water intake and achieve their hydration goals. The calendar feature allows users to view their daily, weekly, and monthly performance, enabling them to track their hydration habits and challenge themselves to maintain a high streak rate. By drinking the right amount of water every day, users can enjoy the benefits of improved hydration.
