The Hidrate Spark Steel Smart Water Bottle ($70) comes with an app that is the hub behind the analytics of your hydration habits and goals. The home section tracks your daily water intake, shows your progress, current target for the time of day, and how much you have left to achieve the daily goal. You can view your monthly progress in the history tab. You can share your progress and results with friends and join app-driven challenges in the social tab. Customise your glow reminders, your Hidrate Spark smart water bottles, and more under the bottles or settings tab. You can even set up the exact times you wake up and go to bed, so the bottle doesn't randomly light up when you are asleep. The app calculates your hydration goal based on the specific parameters you put in, such as your age, weight, height, activity level, and if you are pregnant or nursing. However, you can manually decide your own hydration goals.
