The Best Sleep Gadgets for 2025

Gaining insight into your sleeping patterns is the first step toward identifying problems and fixing them. Fortunately, sleep is a standard health metric among fitness trackers and smartwatches. When you are evaluating your options, look for a device that can track your sleep stages, overnight heart rate variability (HRV), breathing/respiration rate, blood oxygen saturation level (aka SpO2 or Pulse Ox), and skin temperature.

The Fitbit Charge 6 ticks all those boxes. It tracks the amount of time you spend in light, deep, and REM sleep, and its companion app offers graphs of your sleep stages, sleeping heart rate, and more. It also gives you a daily Sleep Score that can help you quickly gauge the quality of your shut-eye. These insights can be a good wake-up call if you’re not getting enough rest.

The Charge 6 and other Fitbit devices also track your estimated oxygen variation, or the changes in your breathing as you sleep. This information can potentially help you identify signs of sleep apnea and other sleep disorders.

Garmin and Polar wearables also generally do an excellent job of tracking your rest. The Garmin Venu Sq 2 and Garmin Vivoactive 5 both have a Pulse Ox sensor that can monitor your blood oxygen saturation on demand, throughout the day, and while you sleep. They also track your overnight respiration and report your average, highest, and lowest number of breaths per minute.

If wearing a tracker on your wrist to bed is too uncomfortable, you might prefer a smart ring like the Oura Ring 4. It looks like a basic metal band, but it houses small sensors that monitor your activity, physical and mental health, and sleep.

Smartwatches are also capable of sleep tracking, but they tend to be bulkier and have shorter battery lives, which makes them less suitable for overnight use.

Overnight, the Apple Watch Series 10 monitors your sleep and other key health stats like wrist temperature and respiration. Apple’s temperature sensing feature doesn’t support on-demand readings like a basic thermometer, but it frequently samples your wrist temperature overnight and tracks changes from your baseline (such as +0.25 Fahrenheit) to let you know whether you’re running hotter or colder than usual.

Blood oxygen saturation monitoring remains unavailable on Apple Watch models currently being sold in the US, but the Series 9, the Series 10, and the Ultra 2 support a new overnight metric introduced as part of watchOS 11 called breathing disturbances that can be used to detect sleep apnea. The Apple Watch also supports a range of third-party apps that can help you get a more complete picture of your sleep patterns such as such as AutoSleep or Pillow.

When it comes to sleep tracking, Samsung smartwatches have a slight advantage over the Apple Watch. The Galaxy Watch 7 supports sleep apnea detection, SpO2 monitoring, and shows your actual overnight skin temperature readings instead of just your devitations. Moreover, the Galaxy Watch can work together with your smartphone to listen for snoring and even record it, a feature that is only available on the Apple Watch via third-party apps. In the morning, the Galaxy Watch offers a sleep quality score and tips for improving your rest. 

Many fitness trackers and smartwatches also let you set silent alarms that wake you up with a gentle vibration on your wrist. This is handy if you share a bed with someone or have roommates in a home with thin walls. You can find this feature on the Apple Watch, the Fitbit Charge 6, the Garmin Venu Sq 2, and others.

As for contactless alternatives, we highly recommend the second-generation Google Nest Hub, which uses imperceptible motion-sensing technology to track your sleep from a bedside table without physically touching you. The SleepScore Max is another contactless bedside sleep tracker.

Another option is to throw out your old spring mattress and upgrade to a high-tech smart bed like the SleepNumber 360 i8. But what does a smart mattress offer over a traditional one?

The Sleep Number 360 i8 features built-in sensors that track your sleep and other health metrics such as respiration, heart rate, and HRV. Some smart mattresses can even pick up sound and elevate your head to stop you from snoring. The other component is a companion app, which lets you view your sleep data, overnight health metrics, and trends. This information can help you determine what is and isn’t working so you can adjust your lifestyle accordingly. You might, for instance, notice that you sleep worse on the days you drink coffee in the afternoon or better if you work out during the day.

Sleep Number’s SleepIQ app also lets you adjust the firmness of your mattress, from ultra-soft to extra-firm and anywhere in between. Sleep Number’s FlexFit 3 adjustable mattress base can even warm your feet to help you drift off faster and elevate them to improve circulation.

The big catch with smart mattresses is that they cost a pretty penny. If you’re not that much of a high roller, there are more reasonable options that work with your existing mattress. The Withings Sleep is a thin pad that goes under your mattress and tracks your sleep cycles, heart rate, and snoring. It even lets you control compatible smart lights and thermostats by simply getting into and out of bed.

If temperature issues keep you up, a smart mattress topper like the Eight Sleep Pod Pro Cover or the Perfectly Snug Smart Topper may provide some relief. Both let you adjust your existing bed’s climate from hot to cool via your phone. The Eight Sleep cover offers a wider temperature range, sleep-tracking abilities, and smart alarms, but we found that Perfectly Snug’s air-based system is better for combating night sweats. 

To deal with snoring, you also might want to consider a pillow insert, like the Smart Nora. It contains a pump that inflates when a bedside companion device hears snoring.

If noisy neighbors are your biggest problem, there are plenty of solutions that can drown out those distractions.

The Ozlo Sleepbuds are earbuds that aim to help you drift off and sleep soundly. We haven’t yet tried them, but they promise to block out noise, such as snoring and outside traffic, with active noise cancellation while playing your music of choice until you fall asleep. They’re also specifically designed to be squishy and comfortable in your ear, even if you’re a side sleeper.

A white noise machine can also block out the world and offer some peace of mind. The Dreamegg has 24 built-in white noise, fan, and nature sounds, as well as a nightlight function. You can leave it on all night or set a 30-, 60-, or 90-minute timer with a memory function that lets you automatically use your last sound each time. The Hatch Restore 2 is a smart alarm clock that can lull you to sleep with soothing sounds and wake you up with a sunrise-simulating light.

Virtual assistants like Alexa and Google Assistant can play soothing sounds, guided sleep meditations, restful music, or tell you a bedtime story to help you get to sleep. Besides the sleep-tracking Google Nest Hub, our favorite virtual assistant-powered bedside companion is the Amazon Echo Show 5. It’s the most affordable smart display available, and its small size makes it a good fit for your nightstand. If you don’t want another screen in the bedroom, you might prefer a smart speaker. The Amazon Echo Dot With Clock features an LED display that shows the time and other useful information. It also integrates motion sensors that let you snooze alarms with a tap.

Before settling in for the night, you can try winding down with a relaxing meditation. The Smiling Mind app (available for Android and iOS) is free and offers guided sleep meditations. The Calm app, another favorite, features a sleep section with slumber-inducing stories and much more.

If you’re new to meditation or easily distracted, you might want to check out the Core Meditation Trainer. You hold the orb-like device in your hands as you stream guided meditations via its companion app, and it gently vibrates to help you relax and focus. As you meditate, sensors on top of the device measure the electrical activity of your heart through your thumbs to quantify the benefits of each session on your body. It offers a selection of guided meditations specifically designed to help you prep for sleep.

Smart home tech can also help you make sure that your bedroom environment is conducive to rest.

Try using smart bulbs for soothing lighting. Most color or ambient white bulbs, such as the AiDot Linkind Matter Smart Light Bulb, let you create bedtime and wake-up routines. Since blue tones keep you up, you can adjust your lights to a warmer, yellower tone past a certain time. Likewise, you can program a gradual fade-in to intense blue-tone lighting that mimics natural daylight to slowly wake you up in the morning.

A smart fan can keep you cool at night while offering the convenience of voice and app control. The Dreo Smart Ceiling Fan (CLF521S) has a sleek design, built-in Wi-Fi, adjustable LED lighting, and multiple fan speed settings, all for a reasonable price. If you don’t want to install something new, the Dreo Polyfan 704S is a smart pedestal fan that allows for omnidirectional oscillation.

For more precise temperature control, consider springing for a smart thermostat or a smart air conditioner that you can adjust with your phone or voice so you don’t have to get up after you’re already comfy. The Ecobee Smart Thermostat Premium has a customizable sleep setting for easy adjustments, and you can schedule it to automatically set your preferred sleeping temperature in the evening. Our favorite smart air conditioner, the Wi-Fi-enabled GE ClearView PHNT10, is impressively quiet and does a superb job of cooling without blocking the view from your window.

If your allergies flare up at night, a smart air purifier could help. The Dyson Purifier Cool TP07, one of our favorite air purifiers, tracks pollution levels and doubles as a fan that can keep you cool.

If you don’t want to spend much, countless free and affordable mobile apps can also help you get more sleep. They tend to fall into one of three categories: tracker, smart alarm, and white noise.

Your iPhone can help you create a nightly routine, limit which apps you use at bedtime, and automatically put itself into Do Not Disturb mode before you drift off.

SleepCycle is a free app that uses your phone’s microphone to track your sleep patterns and can wake you up at an optimal time when you’re in a light sleep.

For smart alarms, we can attest to the effectiveness of Alarmy (available for both Android and iOS). If you use it properly (no cheating), there is no defeating it other than to delete it from your phone. The gist is that the app requires you to take a geo-specific photo, shake it furiously, or solve a math puzzle to turn it off. You can’t turn down the volume, you can’t hit snooze, and rebooting does nothing.

Moreover, there are myriad white noise apps to choose from, and for some people, a little whirr is all they need. All in all, sleeping smarter doesn’t have to be rocket science. No matter your budget, there’s plenty of sleep tech available to help you get a better night’s rest.
