Owlet Smart 2 & 3 Sock Review

To have a happy healthy baby is the dream for all parents and they would do anything to keep their baby safe. Parents want to monitor their babies remotely without risking waking their sleeping children.

But, how do you know your baby is safe when you put them in their crib? What if they suddenly have breathing difficulties, and they can’t get any help because you are not around them? It’s a common anxiety for any parent, especially new parents – but thanks to technology you can get some much-needed peace of mind, because of this very special baby monitor, an Owlet Smart Sock.

What Is An Owlet Smart Sock?

The Owlet Smart Sock is the first home baby monitor to track oxygen level and heart rate as well as sleep trends of healthy babies. The Owlet Smart Sock has a user-friendly design and is easy to use for new parents: you simply place it on the baby’s foot so that it is in contact with the baby’s skin. It even fits under a regular sock or a set of footie pajamas.

Owlet Sock has an essential feature that sets it apart from standard baby monitors. It has a built-in pulse oximeter, which allows parents to know about their baby’s oxygen levels and heart rate. You can use the Owlet monitor to track and record your baby’s levels and quality of sleep for up to 30 nights. The Owlet sock is suitable for babies of 5lbs-30lbs and should only be used whilst your baby is sleeping.

Parents can use the Smart Sock with the knowledge that the Owlet monitor has been clinically tested and approved as safe for babies. Although it’s not machine-washable, Owlet Smart Sock is easy to clean by hand using a mild detergent and lukewarm water.

Owlet App works perfectly with both Android and iOS devices, and the base station can also display alerts so parents can continue to monitor their baby day and night, even when the app is closed. Your Smart Sock needs to be connected to Wi-fi to receive the baby’s well-being history.

Disclaimer: Owlet Sock isn’t a medical device, and Owlet itself never recommends using this product to replace a medical device that your baby needs. Keep in mind Owlet does not cure, treat, diagnose, or prevent any disease.

Who is Owlet?

Eight years ago, Owlet co-founder Kurt Workman began work on an in-home infant pulse oximeter. His reason was very simple: as a parent, he wanted his kids to be completely safe when they were in their crib alone.

Workman was concerned about the potential of a hereditary heart condition that could impact his children. Workman has dedicated his time and energy to creating a safer world for infants and a better quality of life for parents ever since and then.

In 2015, Owlet shipped the Owlet Smart Sock unit to their first customer. By 2016, it was nominated for the “Best Startup of CES” award. The Owlet Smart Sock received thousands of good reviews across the United States, and since 2017, the Owlet Smart Sock has been available internationally.

Why Do You Need A Baby Monitor?

A baby monitor is a useful device for tracking your baby’s respiration from their movement and oxygen levels. It helps you to see or hear your baby from anywhere in the house. It is also easy to use because parents only need to clip it into their baby’s clothing or diaper.

In most cases, parents use a baby monitor for their own peace of mind. Parents who know all of that information feel more relaxed and it’s also a good way to keep your baby healthy and safe. 

The Owlet Smart Sock is a baby monitor that fits on the foot of your baby, just like a regular sock. Safe for newborns and up to eighteen months, the Owlet monitor provides a warning to the parents when your baby needs attention because their well-being has left the recommended ‘safe’ zone. 

More than 1,000 parents have admitted that when they purchased the Owlet Smart Sock their life changed for the better, and it makes them feel safer and sleep better – both for themselves and their babies.

The Benefits of An Owlet Smart Sock?

Aim of Owlet Smart Sock

Although Owlet Smart Sock has many functions and being able to monitor your baby’s oxygen rate is unique to the Smart Sock. The soft fabric fits securely on your baby’s foot and won’t slip off during their sleep, however much they toss and turn. Your baby won’t even feel the Owlet Smart Sock, so it will have no adverse effects on their sleep schedule.

Owlet Smart Sock also uses the same technology of pulse oximetry that you will find in the office of any health professional. It only uses low-energy Bluetooth that is completely safe for your baby.


Parents can be hesitant to try new technology. When you have a new baby to care for, it’s hardly the time to try to get to grips with a new device! But the Owlet Smart Sock is incredibly easy and fast to install, making life that little bit easier.

During setup, you can set the specific low and high zone levels for heart rate and oxygen level. This means you can use your pediatrician’s advice to tailor the alerts to your individual child. When your baby’s oxygen levels and heart rate stay within these zones, the base station glows green. A change in any of the levels will make the base station turn yellow, this indicates that there’s been a change, but the levels are still safe.

When the oxygen levels and/or heart rate are higher or lower than the programmed highs and lows, the base station and Owlet App will notify you with an alarm and you should check your baby immediately.

The Owlet Smart Sock 2 versus Owlet Smart Sock 3

Every time you purchase a new Owlet Smart Sock 2 or 3, you will get:

  • 2 fabric socks, both suitable for 0-18 months, for babies of 5lbs-30lbs.
  • Owlet App Information, which Owlet App works with Android 4.4 and newer, or iOs 8 and newer.
  • Smart Sock Sensor.
  • Charging Cords.
  • Base station.

Additionally, with the Owlet Smart Sock 3, you will get new features with more benefits in addition to those above, such as:

  • “Drop & Go” faster charging, where you only need to place your smart sock into the base station to charge it.
  • More accurate readings through babies’ gentle motion.

The Owlet App

One of the reasons that the Owlet Smart Sock is unique compared to other baby monitors is the Owlet phone App. Parents can download Owlet App both on their Android or iPhone. Keep in mind to connect the Owlet base station to your Wi-Fi network so it works smoothly.

To set up the Owlet App, you have to answer some basic questions about your baby, including the limits for heart rate and oxygen levels, and your baby’s age. Then you are fully set up to monitor your baby.  The Owlet app is set to your child’s individual levels giving you peace of mind that any variations will be caught by the monitor.

Owlet App

After you finish the installation, the app shows you the base station status, battery level, as well as the baby’s blood oxygen and heart rate. Not only that, but you can also review your baby’s sleep history and trends, so you will know about your baby’s sleep quality and be reassured that they are getting what they need. It’s great to have all that information at your fingertips in a phone app.

Battery life

Both Owlet Smart Sock 2 and 3, have a battery life of up to 16 hours on one full charge. You can fully charge your Owlet Smart Sock in just 90 minutes. If you don’t have that long, a 20-minute charge will give you 8 hours of use. Whenever you need to charge the smart sock, you need to put the sock’s monitor onto the base station.

Helping parents sleep better at night

Most parents want to sleep well, especially after long days of work and baby chores, sometimes without a break. The Owlet Smart Sock gives parents the peace of mind that their baby is being monitored whether they are napping or asleep in their crib.

Although the Owlet Smart Sock can’t replace a medical device, these smart socks feature an oxygen pulse meter and will show you accurate percentage points every time. Parents can use it for different babies or twins, but you will need to create different accounts for each baby because of their different characteristics and needs.

Different from another baby monitor, you still can use Owlet Smart Sock without Wi-Fi because it connects to the base station via Bluetooth – so you would still be able to monitor your baby even when there’s a technical error on your Wi-Fi.  Keep in mind that you won’t get any notifications from Owlet App if you set your phone on airplane mode.

False alarms of Owlet Smart Sock

Some reviews say using the Owlet Smart Sock is not worth the money because it can give false alarms. However, false alarms might occur due to incorrect fitting of the Owlet Smart Sock. If you are unsure about how to use the Owlet Smart Sock properly, you can watch the video through the Owlet App or read the instruction manual.

They can also occur when your baby is crying because their heart rate and oxygen level are increasing and their distress causes their rates to leave the safe zone. To avoid this, you can remove the sock or turn off the monitor through the Owlet App or the base station while you are tending to your baby.

Cost of An Owlet Smart Sock

Parents can purchase the Owlet Smart Sock package for under $500. The good news is Owlet offers a payment plan with Affirm, so you can pay off the device slowly with a payment as low as $25 each month.
