The HidrateSpark PRO STEEL is a stainless-steel, vacuum-insulated chug that keeps drinks cold for up to 24 hours. The LED smart sensor “puck” glows to remind you when it’s time to drink and tracks your water intake by syncing via Bluetooth to the HidrateSpark App. The HidrateSpark PRO STEEL bundle includes both a chug and a straw lid. Throughout each day, HidrateSpark PRO STEEL calculates and adjusts a personalized hydration goal based on your body and activity level. The sensor puck tracks how many ounces or millimeters you drink and then records it via the app on your iPhone, iPad, and Apple Watch. The free HidrateSpark App syncs seamlessly with the HidrateSpark PRO STEEL. Once you create an account, the app can access Apple Health for your personal info and step data—which it uses to adjust your daily hydration goal. The app also pushes every sip it records back to Apple Health, allowing you to see all your data in one place. You can also keep track of your consumption on the Apple Watch and easily add amounts of water that you drink from sources other than the HidrateSpark PRO STEEL bottle.
