The sensor puck tracks your water intake by measuring the amount of water in the HidrateSpark Steel Smart Water Bottle ($70). When you first get the bottle, you have to calibrate it so the puck can accurately detect the weight of an empty bottle, full bottle, and everything in between. The puck will send water intake data to the app via Bluetooth throughout the day, and you can view your progress in real time with numerical results. By far, this feature is what makes the bottle worth it! Seeing how much water I actually drank throughout the day was eye-opening and, in turn, motivating. Just like how you want to close all three fitness rings on your Apple Watch, the HidrateSpark Steel Water Bottle pushed me to complete my hydration goals. Although you can manually add water intake like traditional habit-tracking apps, the real-time data kept me accountable for my water intake, thus motivating me to reach for my bottle regardless of a glow reminder.
