Mark One, the company that's currently working on the Vessyl smart cup that can measure the nutritional content of any liquid, today launched an interim product that's designed to track how much water a person drinks in a day.

The Pryme Vessyl is a smart cup that measures all of the water that a person drinks during the day, using the data collected with a proprietary hydration algorithm that lets users know if their hydration needs are being met. It uses decades of research on hydration to determine an optimal or "Pryme" hydration level for every person based on factors like age, weight, sex, and activity level. The data collected by the Pryme Vessyl is compatible with the Jawbone UP and Apple's own Health app.

Many of us still follow the 8 cups per day, one-size-fits-all approach to water consumption, but everyone's hydration needs are unique--fluctuating day-by-day, and even hour-by-hour. Pryme captures a variety of factors such as height, age, weight and sex, as well as changing variables like sleep and exercise, to help you understand your personal hydration needs.

Design wise, Pryme Vessyl is a 16-ounce cup that has a glass interior with a soft-touch white exterior and a nickel-plated bottom. It includes a spill-resistant lid that can be flipped back with a thumb, and the Pryme Vessyl team tells MacRumors that it's both highly durable and reliable.

There are sensors built into the cup to detect each time a person takes a sip. In addition to water, it can hold any hot or cold beverage, so it can be used with other liquids like tea or juice. Though it's safe to use with hot liquids, the electronics inside prevent it from being dishwasher safe.

A blue line on the side of the cup, activated with a tilt, lets users keep an eye on their hydration levels throughout the day to make sure they're getting enough water. Pryme Vessyl uses inductive charging and attaches to an included base, so it's simple to charge. Its built-in battery is able to last for up to five days per charge.

Pryme Vessyl can be purchased from the Vessyl website for $99 and it's also available online at Apple.com and from select Apple retail stores in the United States and Canada.


All customers who previously pre-ordered the Vessyl will receive a Pryme Vessyl for free. The Vessyl remains in development with no prospective launch date as the Mark One team works to transition from prototype to production while maintaining accuracy.

Honestly for $100, just drink a bit more water and judge by the color in your toilet

I have been working on a device to measure my water intake too! It's called a Bottle. To be more specific, a two liter transparent plastic bottle. Thanks to recent software update it is easy to read my hydration level. Unfortunately it does not adapt to gender or age automatically (BottleOS 2 coming soon) so you have to google your ideal daily water intake and... gasp... remember it. Once you completed that step, Bottle will help you stay hydrated no matter what.

I am going to introduce Bottle on Kickstarter soon, you should expect the price to be approx $89.

Drink when you're thirsty. Sip a little more for good measure.

I just saved you $99.
