Sleep Routine: Tracker and Alarm, $7/month or $60/year (iOS/Android): There are several sleep tracking apps, so you don't necessarily need a new gadget. We tested the sleep routine on an iPhone 14 Pro. The app provides a nightly report dividing your sleep into wake, light, deep, and REM. The results were accurate and seemed to closely match the Ultrahuman Ring Air. As you add notes to better understand your sleep, sleep pattern analysis builds and shows you statistics over time. The smart alarm function gently wakes you up. You can try out the sleep routine for a week before you have to subscribe. problem? The app can be a bit unstable. Several times a week, I would get an error message in the morning with no reports or very little sleep. Annoyingly, no reason was given for the failure.
Withings ScanWatch 2 for $350: Sleep with the Withings ScanWatch 2 (7/10, WIRED Recommended) and get a sleep score out of 100 in the morning. It covers the same four stages as other trackers (awake, REM, shallow, deep), but it has a PPG sensor to measure your breathing rate. You can also track your heart rate, body temperature, and blood oxygen levels. ScanWatch 2 provides rich data and advice in the Withings app. However, some people may find it bulky and difficult to sleep on, and there is also the problem that it is difficult to distinguish between light sleep and when you are awake and lying in bed.
Google Nest Hub 2nd generation for $79: The second-generation Nest Hub uses radar to track your sleep. That means you don't have to wear anything, but it also has a microphone to track snoring, sleep talking, and other nighttime sounds. I love having a Nest Hub on my nightstand for smart home control, family photos, and listening to sleep sounds and podcasts in bed, but sleep tracking always overestimates my REM phase. I was missing the wakefulness period recorded by other trackers. Nest Hub was an outlier when using multiple trackers at the same time.
Muse S Gen 2 headband, $400: This headband is equipped with sensors that can track brain activity similar to electroencephalograms (EEG), as well as accelerometers and gyroscopes, as well as PPG sensors that measure heart rate and blood circulation. It's a meditation aid primarily designed to help you relax, but it also tracks your sleep, recording your heart rate, breathing, time to fall asleep, and how much you move around to provide an overall sleep score. can also do. Sadly, I found it uncomfortable to wear and often woke up to find that sleep tracking was failing. This was usually because I took it off at night. It's too expensive.
Kokoon Nightbuds $285: Combining earbuds with sleep tracking is a smart idea, but I found it hard to fall asleep with Nightbuds on. These small earbuds plug into a curved control unit designed to fit into the back of your head. Everything is covered in flexible silicone, so it's relatively comfortable. A companion app can play meditations, soothing sounds, and sleep stories to help calm down or drown out a snoring partner. You can also connect via Bluetooth and play your own content. Sleep tracking is limited, showing the familiar four stages of her sleep, sleep efficiency, and consistency, but I often found those to be off when I woke up in the middle of the night, cutting my sleep tracking short . I'm about to test the Philips Sleep Headphones, which appear to be a rebranded version.
Biostrap Kairos $900: This lightweight wrist-worn band has a PPG sensor and accelerometer to track heart rate, breathing, and HRV. It tracks your sleep by waking, light sleep, and deep sleep (REM sleep will be added soon) and combines it with biometrics to provide a sleep score. We'll also ask you about your sleep quality and how refreshed you feel each morning, as well as how you felt when you woke up and before you went to bed. Although it appears to be very accurate, it is designed for researchers, medical staff, and organizations who want to monitor the health of their employees or study the impact of new services or products, so most people will not cannot be purchased.
