SleepWise™

Wake up to better days.

Sleep affects how you feel and how well you perform when you’re awake. SleepWise™ gives you daytime alertness insights that help you perfect a bedtime routine so you can face your daily challenges sharp and ready.

See your daytime alertness forecast.

Understand when it’s the optimal time for sports, work, winding-down, or a nap. SleepWise™ predicts how your sleep boosts your energy for each hour of the day.

SleepWise™ doesn’t just keep track of the amount and quality of your sleep. It also analyzes how well your sleep-wake cycle aligns with your body’s internal circadian rhythm to determine your mental alertness for the day ahead.

Adjust your sleeping habits.

Sticking to a regular bedtime and wake-up time is great for your sleep. When your sleep and internal circadian rhythms are in harmony, you’ll be more focused, think clearly, and perform better in sports and in life.

SleepWise™ visualizes the effects of sleep debt and irregular sleep-wake rhythm, helping you make small adjustments to find your ideal sleeping schedule.

The Science

The SleepWise™ algorithm uses a biomathematical model to assess how recent sleep, time awake, and the body’s internal circadian rhythm impact on your day’s alertness levels.

To predict how sleep boosts your alertness during waking hours, the algorithm evaluates sleep amount, quality, and timing against personal sleep need and internal circadian rhythm.

Biomathematical modeling is a generally accepted method to predict the effects of sleep loss on sleepiness and performance during waking hours.
