Already Wear a Smartwatch? Why Do You Need an Sleep AI Lamp?

When we started building Shuibao, our app for Apple Watch, we discovered just how much people care about their sleep. Many wear their watch to bed every night.

But we also heard plenty of complaints. Wearing a watch around the clock can leave the skin underneath feeling stuffy and prone to irritation. Finding time to charge it becomes a hassle, too.

More importantly, understanding sleep takes more than data from your wrist. A watch can track sleep, but its ability to support the full experience—from winding down and feeling comforted to waking up—is limited.

That is why we decided to build the Sleepal AI Lamp.

Whether we are developing the Shuibao app or the Sleepal AI Lamp, we are working toward the same goal: interpreting more comprehensive sleep data, sharing health knowledge, and helping people achieve better sleep more naturally and effectively.

Put simply:

The Shuibao app helps you understand your Apple Watch sleep data. It turns the sleep, naps, trends, and sleep stages recorded by your watch into clear insights, so you do not have to stare at a jumble of numbers and worry about them every day.

The Sleepal AI Lamp is our exploration of the future of more specialized, unobtrusive sleep intelligence. It watches over your nights quietly, recording sleep data more accurately and comprehensively without anything to wear.

Sleepal connects with Apple Health and Android Health Connect, bringing daytime and nighttime data together. You can wear your watch during the day and leave your nights to the Sleepal AI Lamp, designed specifically for sleep.

Not everyone wants to wear a watch to bed. Even if you are used to it, we encourage you to take it off at night: give your wrist a breather and your watch time to recharge.

There is more to sleep than the data your wrist can capture.

Snoring, sleep position, breathing patterns, the bedroom environment, light, sound, and when you are woken in the morning are all better understood from the bedside. Sleepal aims to build a fuller picture of what actually happens in your bedroom, including:

Are you asleep, or simply lying still?

How severe is your snoring? Is it related to your sleep position?

Are temperature, noise, or light affecting your sleep?

For sleep intelligence to be taken seriously, accurate data monitoring must come first. As pioneers in this new category, we spent nearly three years working toward that goal—and finally achieved it.

In our arXiv paper, co-authored with Professor Thomas Penzel, President of the World Sleep Society, Sleepal was validated against 1,022 nights of hospital PSG data and achieved κ = 0.695. This is higher than the corresponding figures publicly reported for Apple Watch (0.68) and Oura Ring (0.65). If you are interested in the technology, we invite you to read our paper.

More importantly, a bedside device can also help improve sleep. Using accurate sleep-stage detection, it can turn off the lights after you fall asleep, adjust the air conditioner, humidifier, and curtains as your sleep and environment change during the night, and wake you with gentle light when you are in lighter sleep and better ready to wake.
