What is Pryme? What does it measure?

Pryme is a dynamic, unique estimate of your personal hydration needs throughout the day. We combine a variety of personal and environmental factors to determine your optimal state of hydration as you go about your day.

The Pryme line (on the cup and in the app) will rise and fall based on how well you've met your current hydration needs. When you reach your Pryme (your optimal state of hydration for that time) the Pryme dot on your cup will turn blue. The blue light means you’re Prymed for your moments of greatness.
