What does a smart ring do?

A smart ring is an electronic device worn around your finger and can collect many different types of data. Smart rings are useful for many reasons, such as sleep tracking, blood pressure, blood oxygen levels, heart rate, activity tracking, and other features. A smart ring can connect to your mobile devices with Bluetooth capabilities and help the user monitor sleep, track sleep apnea, body temperature, and other biometric data.

A smart ring can also provide other functionality, such as using an NFC chip connected to your bank cards to make contactless payments.

Smart rings can also be useful for providing notifications from other devices, such as updates from online accounts, phone calls, or reminders for to-do lists.

How to use a smart ring?

A smart ring can be worn on the index finger, ring finger, or any finger of your choosing. All you need to do is wear your ring like normal, and the smart ring will automatically track your data and utilize its features.

Smart rings require little to no additional setup to track your data. You need to wear your ring like a traditional ring and go about your life like normal.

Depending on the battery power of your smart ring, you will need to place your ring on the charging dock occasionally to charge the battery.

How accurate are smart rings?

Most smart rings collect various data that can be compiled into useful metrics for improving health and making life easier. Many smart rings are similar in the data they collect, but some smart rings are more accurate than others in different usage scenarios.  

The smart ring options have evolved drastically over the last several years, and advancements in wearable tech have made smart rings more accurate than ever.

Smart rings can be used to accurately track heart rate, sleep, blood oxygen level, body temperature, and activity tracking, and it is much more convenient than other wearables.

Smart watches

Although smartwatches are very popular, they cannot provide the high level of accuracy provided by smart rings due to their different wearing positions. Smart rings can make more precise measurements, as well as take measurements with minimal interference.

The battery life of smart rings also lasts much longer than that of smartwatches, which need to be charged more frequently, meaning that less data is being measured.

Smart ring during COVID

A smart ring is an excellent consideration for the COVID-19 pandemic. Many smart rings offer to monitor your blood oxygen level, which is an important metric for someone who has COVID. Monitoring blood oxygen levels is a great way to track whether or not there is enough oxygen in your blood, which is good news for COVID patients.

COVID and heart rate


Another important metric that smart rings can measure in regards to COVID is your resting heart rate. If you become infected with the virus, it is important to monitor your heart rate if the infection becomes problematic.

NFC Smart

Another benefit of smart rings during COVID is the NFC chip. Using NFC for contactless payments is a great way to protect yourself from germs out in public. By waving the ring on your finger over the sensor for contactless cards, you can make payments without the need to make contact with surfaces.

NFC Compatibility

There are two categories to consider when looking for an NFC ring: passive options, which can be used for contactless payments, POS systems, integration with a biometric security company, and a smart NFC ring that incorporates NFC into its broader functionality.

The smart NFC ring that you choose should be based on your needs and incorporated into the systems you already use in your daily life.

Things to consider when buying a smart ring

There are many different options when it comes to buying a smart ring. To find the best ring for you, it is helpful to decide what you want out of your ring and what data you want your ring to collect. This buyer’s guide can help you find the best ring for your needs.

Smart ring Features

The smart ring market is full of options, and before you decide on the ring for you, it is a good idea to decide on the features you want your ring to have beforehand.

Data accuracy

What data do you want your smart ring to collect? Do you want a ring that can track sleep, heart rate, and blood oxygen levels? Do you want a smart ring that acts as a fitness ring? Does your ring need to be water-resistant or have long battery life? Should your smart ring connect to your phone or other devices?

All of these questions are important when it comes to choosing the best smart ring for your lifestyle. Whether you prefer sleep tracking, fitness tracking, or an NFC smart ring, there is a ring with all the features you need.

Most smart rings can connect with your other electronic devices to retrieve the data that smart rings collect. The more data that smart rings collect typically means you want a ring with longer battery life to get the most use out of your ring.

Exporting your data is also an important factor to keep in mind when shopping for smart rings. The ability to see all of your data in one easy-to-read format is crucial for understanding your habits and vital signs.

Smart Ring Form Factor

A smart ring will live on your finger, so the smart ring form factor is something to consider.

Do you want your smart ring to have a subtle design that looks like a regular ring, or do you prefer a ring that looks more like a futuristic gadget on your finger?

The form factor will be dependent on the functionality of the ring you choose.

Looks are important

There are plenty of options available on the internet for smart rings for picking a smart ring that resembles a regular, circular ring. Smart rings can come in all finishes, like rose gold, silver, volcanic magnet, and energy stone.

You want a ring that looks good on your hand, regardless of the outfit you wear or the setting in which you’re wearing it.

Most importantly, however, you should also feel good while wearing the ring.


To pick the right size ring, a sizing kit is a way to go. A sizing kit comes with multiple plastic rings in a variety of sizes in order to help you find the perfect fit for your ring.

To use the sizing kit, try the different rings on the finger you want to size until you find the one that fits best.

A ring should fit snugly around your finger but not so tight that you can’t take it off when you need to place it on the included charger. Your ring should be comfortable to wear when you are awake and while you sleep or exercise, without falling off.

If your smart ring is too small, you may restrict blood flow, which will obscure the data and give you inaccurate readings.

Alternatively, if the ring is too large, then the censors will not make proper contact with your skin, and you also run the risk of your ring slipping off during sleep or exercise, possibly losing the ring entirely.

Battery and charging

If you want to use a smart ring for sleep tracking, you will need to wear your ring overnight while you sleep, which means that you want to pick a ring with adequate battery life.

NFC smart rings are typically passive devices that do not need a battery to operate, such as the MClear ring. However, these types of rings do not provide the same features as battery-powered rings.

If you choose a battery-powered ring, it will come with a charging dock used to recharge the ring’s battery.

The charging time and battery life will depend on the ring’s functionality and how you use the ring daily.

Protection measures

Much like traditional rings, a smart ring that you wear 24/7 needs to be able to withstand your day-to-day life. When deciding features for a smart ring, you may decide that you want a ring that is scratch-resistant, water-resistant, and able to stay on your finger while you sleep.

The best smart rings provide all of the protection you need while giving you the functionality you deserve.

When making any investment, you want to purchase the product that gives you the most for your money without worrying about defects or being easily damaged.

The Oura ring provides an excellent finish that is scratch and water-resistant to maintain its beauty while providing full functionality.  

Operating system and device compatibility

When shopping for a smart ring, you must select a ring that can easily incorporate your other smart devices.

If you use an Android device, you want a ring that can communicate easily with your device to provide a seamless compilation of data, but if you use an iPhone, you want a ring that can be used with your apple health app.

Most smart rings can also be connected to smartwatches as an extra way to view the data that smart rings collect.

Additionally, smart rings like the Wellue O2Ring can export your data in various formats, making it simple to analyze your oximetry data in easy-to-read charts, graphs, and however else you may want to view your data.

To get the most value out of your smart ring, connecting your smart ring to your phone or PC is important, so the data it collects is easily accessible to you and any medical professionals you wish to share the data with.
