I use a lot of tech in many areas of my life. This smart water bottle checks all the boxes. It shows where I need to be at any time of day to meet my goal, allows for the use of ice and/or flavoring products, it’s easy to clean, keeps the water cold (or hot), has a lockable flip cap (won’t open accidentally), a very handy but simple strap to carry (I pinch it between my thumb and forefinger), the battery puck lasts for ~1 week before needing a charge (they sell just the puck if/when it stops taking a charge someday in the distant future), the mobile app provides you with current information (e.g., battery level, amount I’ve drink, my goal, color options, control reminders, put reminders temporarily to sleep which is good for mtgs, …), and it looks good (not that I’m trying to show off my water bottle). Pardon the run-on sentence, the HidrateSpark Steel and companion iOS app are very well done and have helped my create a habit of drinking water daily. One last item, the fireworks that go off in HidrateSparkWaterTracker when you meet your goal are just icing on the cake.
