How does it work? 

The Hidrate Spark Steel bottle syncs with the Hidrate Spark hydration app.

The app will ask a series of questions to calculate your personal daily water goal.

Factors that are used to calculate your daily hydration goals include: 

  • age
  • height
  • weight
  • sex
  • elevation
  • exercise
  • and lifestyle habits

The app syncs with your water bottle to track how much water you drink. It will glow to remind you to drink, and you can also enable phone notifications. 

The sensor puck battery lasts about ten days before you have to recharge it. 

The sensor puck is removed to charge and twists in to stay in place.

Is Hidrate Spark Steel accurate?

Clinically proven accuracy within 3% of manual readings through Mayo Clinic trials

Care instructions? 

The lids are dishwasher safe, but the bottle should be hand-watered. Be sure to remove the sensor puck before washing the bottle.
