Go2Sleep Review: The Ultimate Sleep Solution?

By Oktay Ozadam

GO2SLEEP Home Test Device

The Go2Sleep is the latest in wearable technology promising to deliver big results in a sleek, compact design. With so much of our lives spent sleeping, I was immediately interested in this product. As someone who regularly suffers from restless nights, I wanted to see if the Go2Sleep ring could back up the boasts. How much can Go2Sleep benefit you if your nights are less than refreshing? Let's find out.

Innovative Design with Easy Set Up

Directly out of the box Go2Sleep makes an impression. Sporting a weight of only 6 grams, I was immediately drawn in by design. The cylindrical shape of the device is lightweight and easy to wear.

Where I started to have my doubts was when it came to wearing the device all night. I'm already a light sleeper so I questioned whether or not Go2Sleep would cause problems.

SleepOn, Go2Sleep's developer, states that the device is light enough to cause no added discomfort to the user. I found this to be a large claim as I know that some people may have trouble getting used to the feel of a ring initially. Luckily, Go2Sleep is available in three different sizes of silicone ring holders so finding the right fit for you shouldn't be difficult. This leads me to believe that the design of the ring won't be much of a problem for most people, so Go2Sleep wins a point there.

Go2Sleep's included charging station also possesses a pleasing, user-friendly design. Featuring a magnetic strip that the ring attaches to, it's easy to keep the device charged. By placing the charging base on your bedside table, for example, it's easy to drop the ring to charge each morning.

Go2Sleep wins another point for easy setup. Upon first time use, you merely download SleepOn's iOS/Android app, set a few preferences, and sync your phone. Set up takes little more than two minutes and then…BAM… your new ring is ready to collect data.

User-Friendly Experience and Innovative Features

Let's get more in-depth with those big results promised by Go2Sleep.

From sleep apnea to insomnia, Go2Sleep is said to not only track your zzz's but also deliver complex data in a digestible format. With use, Go2Sleep supposedly improves sleeping habits.

Despite the fact that there are similar devices on the market (more on that later), SleepOn promotes their product as the proactive sleep innovation technology that helps you sleep better. Have you finally found something to rid yourself of those sleepless nights forever? Well, not quite.

The first thing I wanted to find out was exactly how Go2Sleep monitors and delivers user results. Using the capillaries on the human hand, SleepOn promises accuracy tested to medical device benchmarks. I have my own gripes with these claims. After all, SleepOn is marketing a product. Your average user may take these statements at face value. But should you?

Sleep Quality

Go2Sleep's built-in sensors monitor the quality of your sleep each night taking factors such as movement into consideration. While these sensors are accurate for the most part, it is a common problem for some sleep ring trackers to have trouble sensing when the user is actively sleeping as opposed to just lying awake in bed.

When a device promised to improve your sleeping habits has trouble detecting exactly how long you spent sleeping, it can be discouraging. Some users report that they end up staring at the ceiling for 30 minutes or more only to have their sleep tracker report that these 30 extra minutes were spent sleeping. Unfortunately, it seems this problem may also occur with Go2Sleep.

While Go2Sleep's observations do run the possibility of being skewed, it isn't altogether unimpressive in ability. One of the sleep quality features that I find most interesting is the device's "Toss and Turn" measurements. Many users report that the collected data of their movement at night was surprisingly accurate. Go2Sleep tends to get these findings right and used them to compile an in-depth report of your sleeping patterns.

What is included with Go2Sleep?

Sleep Apnea Screening

Sleep apnea currently affects approximately 18 million people in the United States alone. When left untreated, sleep disorder can lead to health risks such as an increased risk of obesity, heart attack, and high blood pressure. SleepOn strives to help Go2Sleep users uncover this disorder via the results of their unique sleep report data.

While you may not suffer from sleep apnea personally, you can likely observe some obvious drawbacks in Go2Sleep's ability to detect sleep apnea. For example, Go2Sleep possesses no way of directly monitoring the respiration rate or measurement of airflow. While other features of the ring can certainly help identify symptoms of sleep apnea, you shouldn't take it as a full diagnosis. When it comes to distinguishing Obstructive Sleep Apnea from Central Sleep Apnea, for example, it's a better idea to visit a physician.

Heart Rate/Blood Oxygen Level Monitoring

There are some things that Go2Sleep does remarkably well, and the heart rate/blood oxygen level monitoring features are at the top of that list.

With Go2Sleep's haptic sensors, you can gain valuable insight into your BPM measurements when asleep. Although this feature is pretty commonplace in today's wearable devices, Go2Sleep does exceed in its ability to explain what these reports mean.

I'd be willing to bet that you don't obsess over your blood oxygen levels on the regular. I can relate! But you may be surprised to see just how much Go2Sleep can teach you about any issues present in your own blood oxygen levels. Thanks to easy-to-read reports and suggestions, you may get a better grasp of your current health quality.

Go2Sleep notifies you instantly when your blood oxygen levels drop too low. When Go2Sleep observes this, it will lightly vibrate to alert you. If you're a light sleeper, you may hear this and immediately assume this feature would annoy you. You'll be happy to know that many users who also describe themselves as light sleepers report that these vibrations were so subtle that they were never fully awakened by them.

SleepOn did a great job of making this feature useful without being bothersome. Go2Sleep's developer clearly aims to increase the chances of natural body repositioning in order to reduce sleep apnea risk. After reading several instances of positive user experience with this feature, I'm confident that this is one promise that Go2Sleep can deliver.

Integrated Reports

Nobody likes trying to make sense of complicated charts and graphs. It's clear that SleepOn took this into consideration when creating Go2Sleep. I found the format of the integrated reports to be very easy to use. Navigating through the data was simple, and I'm sure you will find enjoyment in checking your daily reports.

In each report, Go2Sleep compares your sleeping activity by day, week, and month. This format is especially cool because it makes pointing out trends in your sleep activity easy. You are able to log your daily activities within the app. With this feature, the user can track how their actions during the day later affect their sleep at night.

The tips and recommendations that Go2Sleep offers as ways to improve quality of sleep are interesting, but I can't say that every user will experience a confirmed benefit. While suggestions to read before bed and avoid scrolling through social media are helpful, I feel that the app's advices may not be as personalized as advertised. Most of the tips provided seem to be fairly generic and are easily found in any Google search of the topic.

So Just How Accurate is Go2Sleep?

Let's get to the real question: how accurate is Go2Sleep?

In wearable technology that claims to do as much as Go2Sleep, accuracy is an essential factor. SleepOn is adamant that their device delivers accurate results based upon their own "SleepFit algorithm". Not so fast.

I found some user reviews that are eye-opening at the least. In one review on Amazon, a mother writes that she purchased Go2Sleep in an attempt to monitor her daughter's breathing during sleep. She calls the device "wildly inaccurate" due to testing the low pulse ox levels it reported against verifiable sources. This user claims that her sleep monitor was fully charged, dismissing that as an explanation for such stark inaccuracies.

In another negative review, a user reports very similar results. She also tested the Go2Sleep next to other sources and found different measurements. Even if you give SleepOn the benefit of the doubt and assume that these users may have had defective devices, you can't be sure. Sure, this could be a rare thing- but what if it's not?

It should also be noted that SleepOn's website presents no scientific data to support Go2Sleep's accuracy. While my own testing of the ring presented no major inaccuracies, this is something to consider before buying one for yourself.

Where You Can Find Go2Sleep

If you've decided that Go2Sleep is worthy of your hard-earned cash, the best place to make the purchase is at Go2Sleep's official Indiegogo page. This is where the product received over $90,000 in crowdfunding. You can also get it at the lowest price- $119.

You could also find Go2Sleep on Amazon at the full retail price but it is not available currently.

Other Sleep Tracking Rings To Help You Sleep Better

Every market has competition, and the sleep tracking ring is no exception. Want to weigh your options before making a decision? Here are some other choices. While these rings don't screen for sleep apnea like Go2Sleep, they do have their own unique features.

THIM Smart Ring

THIM Smart Ring aims to assist you in "sleep re-training".

While THIM boasts many of the same features, it differs in execution. As I mentioned, it is a common problem for sleep tracking rings to track sleep when you are actually still awake. THIM solves this problem by seemingly verifying that you're asleep. THIM vibrates every thirty seconds, and you respond by tapping your fingers. If you don't tap, THIM assumes you're asleep and starts collecting data.

When you start to fall asleep, THIM vibrates every three minutes during the first hour, waking you and letting you fall back asleep. THIM's developer states that this encourages you to fall asleep more quickly over time.

Oura Ring

The Oura Ring resembles a typical ring with sensors visible only on the inner band of the ring.

Oura covers a more broad scope of health factors while THIM and Go2Sleep focus predominantly on sleep tracking. With features like a body temperature sensor, infrared LEDs, and a 3D accelerometer, Oura may be the best fit for someone interested in activity tracking alongside sleep.

That being said, Oura tracks sleep stages such as REM, deep, and light as well as sleep trends and quality measurements. If you like the idea of a sleep tracking ring that looks a little less like one, Oura may be an option to consider.
