What are smart rings?

Smart rings are the newest evolution in fitness tracking, joining the ranks of popular smart devices that have become essential in daily life. The first notable entry, McLear's RingPay, debuted in 2013. 

However, these rings have faced challenges in gaining widespread adoption due to technological limitations and competition from larger wearables. Critics often dismiss them as compact versions of smartwatches without groundbreaking features. 

Despite this, major tech players like Apple and Samsung are now exploring their potential, signaling that smart rings could still carve out a significant market.

Unlike smartwatches, these rings offer diverse functionalities without relying on a screen. They discreetly track health metrics, with data accessible on a paired smartphone. 

Additionally, they enable gesture-based control of home devices and facilitate contactless payments. If you're considering investing in a smart ring or simply curious about its capabilities, here’s everything to know about this innovative smart device.

Smart rings are compact electronic bands designed to be worn on the fingers, resembling traditional rings but packed with advanced sensors. 

These smart devices utilize Bluetooth and Near-Field Communication (NFC) technology to track various health and activity metrics, such as heart rate and step count. Depending on the manufacturer, a smart ring may include one or more of the following sensor types:

Photoplethysmography (PPG) sensor – Uses LED light to detect blood volume variations and monitor heart rate.

Accelerometer sensor – Measures body movement, tracking steps, distance covered, and calories burned.

Gyroscope sensor – Works alongside the accelerometer to detect body orientation and movement with precision.

Electrodermal Activity (EDA) sensor – Analyzes sweat levels to assess stress and emotional states.

Peripheral Oxygen Saturation (SpO2) sensor – Monitors blood oxygen levels.

NTC thermistor sensor – Detects body temperature fluctuations.

Unlike smartwatches, these rings do not feature a display due to their compact size. Instead, they sync with smartphones or tablets, where users can access data through a dedicated app. 

These apps, available for various operating systems, allow for customization, notification management, and ID integration. Additionally, many smart rings come with a built-in digital wallet, enabling seamless contactless payments by linking to bank cards or other payment methods.

Bluetooth connectivity ensures real-time data synchronization between the ring and a paired smart device. Some smart rings also integrate with Google Fit and Apple Health, allowing users to consolidate their health data in one place. 

NFC technology further enhances functionality, enabling smart rings to act as authentication keys, remote controls for smart home devices, and secure payment tools in supported locations.

What can smart rings do?

A smart ring's functionality varies depending on the model and brand, with some features exclusive to specific manufacturers. Before purchasing a smart device, reviewing the product specifications is essential to ensure it meets your needs. Here are some common uses of smart rings:

Health Tracking – Equipped with advanced sensors, a smart ring monitors heart rate, blood pressure, step count, sleep patterns, and other wellness metrics.

Contactless Payments – Link a smart ring to bank accounts or cards for seamless transactions. To pay in-store, hover a hand over the POS machine. For mobile payments, tap the phone’s back against the ring.

Smart Home Control – Use a ring as a digital key to unlock doors, adjust thermostats, and switch off lights with simple hand gestures.

Identification & Security – Smart rings can function as Two-Factor Authentication (2FA) tools for online accounts or as digital access badges for workplaces, transit gates, and secured buildings.

Notification Alerts – Many smart rings vibrate or light up in different colors when receiving calls, texts, or app alerts.

Mobile Security – Add a smart ring as a trusted device to unlock a smartphone or tablet without the need for passwords, PINs, or patterns.

Music Playback Control – Manage music effortlessly with a smart ring—play, pause, skip tracks, and adjust volume using built-in controls.

With evolving technology, smart rings continue to integrate more features, making them a versatile and convenient addition to everyday life.

The advantages of smart rings

One of the biggest advantages of a smart ring is its portability. Blending traditional jewelry with modern technology, this smart device offers a stylish way to discreetly manage tasks. 

Unlike other wearables, it operates independently of a phone—only requiring one to sync and view collected data.

Smart rings are particularly beneficial for health-conscious users. While they offer similar features to smartwatches, they provide a more comfortable experience, especially during sleep, thanks to their lightweight design. 

Their continuous skin contact enhances data accuracy, helping users stay informed about vital health metrics. Despite their compact size, these rings house small batteries that consume minimal power.

Certain models, like the McLear RingPay, don’t require charging since they rely on magnetic field induction for contactless payments. Simply holding them near a payment terminal activates the current, allowing for instant transactions via stored payment details. 

Meanwhile, rechargeable options like the Ōura ring feature battery capacities ranging from 15mAh to 22mAh. Though smaller than those found in larger wearables, they can last up to a week on a single charge. 

With no screens to distract users, these smart rings also help reduce screen time while still providing notifications and call alerts.

Water resistance is another key factor to consider. If planning to wear a smart ring while swimming or in rainy conditions, it’s essential to check its rating.

What are the disadvantages of smart rings?

Smart rings lack a screen and function solely as companion devices to smartphones. 

Their compact size limits battery capacity, meaning frequent charge cycles can lead to quicker battery degradation compared to larger wearables. Over time, this may necessitate a replacement sooner than expected.

Sizing can also be challenging, as a smart ring must fit snugly without being too tight or loose. Determining the right size when ordering online is tricky, though some brands offer sizing kits before purchase. 

Typically, users receive a kit, select the best fit, and return it before the company ships the final product. 

However, this process can be time-consuming, and even with a sizing kit, there's no guarantee of a perfect fit. Additionally, in regions where smart rings have yet to gain widespread popularity, sizing kits may not be readily available.

Conclusion

A smart ring is a great option for those seeking a simpler alternative to a smartwatch, but its value depends on individual lifestyle needs. Unlike smartwatches, these compact wearables focus on specific functions, eliminating distractions like mini displays or barometer sensors for weather predictions. Some models specialize in health tracking, while others are designed primarily for contactless payments or a combination of features.
