Smart Jewelry for Women – Reviews

Take a look at our pick of the leading “hidden” smart tech on the market right now.

1. Bellabeat Leaf Urban Our Top Pick

The Bellabeat Leaf Urban is a beautiful pendant that is wearable in many different ways. It can be worn as a necklace, a clip or even a bracelet. The body has a solid feel and is made of wood composite.

It’s an activity tracker and sleep monitor with some additional helpful features. The stress sensibility feature is very clever. It detects when you get too stressed and it will remind you to do some breathing exercises or meditate to reduce your anxiety.

Another useful feature, especially for women, is Menstrual Cycle Tracking. This enables the wearer to keep track of periods and calculate future starting dates. For those lucky enough to be expecting, you can also track the progress of pregnancies.

It has some other necessary features like an alarm, break reminder (in case you have been sitting for too long) and a waterproof rating of IPX6 that can handle splashes and rainfall. Just don’t take it swimming with you!

We actually have a more detailed review of Bellabeat Leaf Urban if you want to learn more about it.

Features:

  • Versatile wearing options (as a necklace, bracelet or clip)
  • Activity and sleep tracking
  • Stress Sensibility – It can predict your stress level
  • Menstrual cycle tracking
  • Meditation, alarm, break reminder
  • Water resistance rating of IPX6

Type: Necklace, Bracelet, Clip

Colors: Rose Gold, Silver

2. Wellue O2Ring Wearable Sleep Monitor

Your doctor has probably used an oximeter on you at some point to measure your SpO2 blood oxygen levels. The Wellue O2Ring Wearable Sleep Monitor does the same thing but from the comfort of your bed. The only difference is that instead of attaching it to your fingertip, you can wear the Wellue O2Ring around your finger like a ring as you sleep.
It uses a touch-button interface that displays both your blood oxygen saturation and heart rate at specific intervals throughout the day. You can also link the readings to the Wellue app—available for both Apple and Android products—to track your readings over a longer period. This will help you determine when your blood oxygen saturation dips throughout the night.
Readings include:

  • Blood oxygen saturation ranging from 70% to 99%
  • Heart rate ranging from 30 to 250 beats per minute
  • 1-second intervals

Overall, the Wellue O2Ring is a little large but, thanks to its expanding band, you can comfortably wear it throughout the night without it cutting off your circulation. You can use it in tandem with the mobile app to graph your oxygen and heart rate throughout the night and then export your information in the morning.

Features:

  • Comfortable ring design
  • Tracks SpO2 blood oxygen concentration
  • Tracks heart rate
  • Links to an easy-to-read mobile app
  • Tracks levels throughout the night
  • Comes with a charger and instructions
  • Bluetooth capabilities

Type: Ring

Colors: Black

3. Misfit Wearables S500BM0RZ Misfit Ray

The Misfit Ray is a simple sports tracker that focuses heavily on style and design. Rather than an interactive screen, it features a single multi-color LED light positioned in a lightweight aluminum tube held in place by a silicone wristband. The tube opens to reveal an internal compartment that houses three battery cells.

As far as its capabilities go, the Misfit Ray weighs in rather light compared to other similar sports trackers. It consists of a vibration motor, a three-axis accelerometer, and a Bluetooth connection. These three features allow it to track your footsteps and your sleep. It will also alert you to any incoming texts or calls.

This lack of hardware means you won’t be able to track the number of steps you climb throughout the day, your heart rate, laps in a pool, or even an accurate read for runs or hikes. However, it does include a unique feature that will buzz and wake you up when you are in a lighter stage of sleep.

Features:

  • A chic and streamlined aluminum design
  • Tracks steps
  • Tracks your sleep cycles
  • Links all data to the Misfit tracking app
  • Will alert you to incoming texts and calls

Type: Bangle/wristband

Colors: Rose gold

4. TMYIOYC Fitness Tracker

Some companies have tried to disguise their sports trackers as a piece of jewelry. With the TMYIOYC Fitness Tracker, it seems to be the other way around. When you want to exercise but also want to wear a beautiful watch, this is the tracker for you.

It features a beautiful watch band with an interactive screen interface that tracks your steps, distance traveled, calories, heart rate, and even blood pressure.

If you wear it during the night, it will continue to accurately measure your vitals as you sleep and record the data to a mobile Wearhealth app that you can check in the morning.

Like many other wristwatch/wristband-style sports trackers, the TMYIOYC Fitness Tracker will alert you to any incoming calls or texts, but thanks to its interactive screen, you can see who the call is coming from. Although you cannot answer phone calls through the tracker, you can read messages on it.

One major downside to the TMIYIOYC Fitness Tracker is that it is not waterproof, so you will not be able to use it in the swimming pool to track laps. As well, the mobile app seems to lack usability. Some buyers have reported that it doesn’t track all of your data and should only be used to set reminders for upcoming workouts.

Features:

  • A fashionable and adjustable metal wristband
  • An interactive screen interface
  • Tracks heart rate, blood pressure, sleep, steps, and calories
  • Connects to the Wearhealth mobile app
  • Alerts you to incoming messages and calls, which you can see on the screen

Type: Wristwatch

Colors: Black, stainless steel, and gold

5. MIJOBS Necklace Compatible with Fitbit Flex 2

Remember how we said that the Fitbit Flex 2 was one of the most adaptable fitness trackers on the market? The MIJOBS Necklace further proves our point. This minimalistic necklace case for a Fitbit Flex 2 features a stylish gold chain that accentuates your fitness tracker as if it were a pendant or a locket.

Unlike strictly sporty designs, the MIJOBS necklace case goes well with just about any daytime or nighttime outfit and is guaranteed to never discolor or fade as you wear it. Its magnetic locking system is made from sturdy Neodymium magnets that bolt your Fitbit into place while your job, walk, or run.

As it is designed to be used with a Fitbit Flex 2, you will be able to track your steps and distance traveled, the number of calories you burn, the duration of your exercises, and the overall quality and length of your sleep. Simply snap your Fitbit into place and wear your necklace.

All data will be recorded to your Fitbit mobile app where you can export it as a graph or chart.
We do not recommend swimming while wearing this necklace though. The large pendant design will drag behind you as you swim and could be uncomfortable on your neck.

Features:

  • A unique 20 in zipper-like chain necklace
  • A sturdy magnetic locking system
  • Electroplated steel guaranteed not to discolor or fade
  • Hold a Fitbit Flex 2
  • Tracks sleep quality and length, heartbeat, calories burned, steps, and more

Type: Pendant/necklace/locket

Colors: Rose gold/silver

6. Invisawear Rose Gold Beverly Necklace Personal Safety Device

Possibly the most beautiful item on this list, the Invisawear rose gold personal safety device stands out among all the other products shown here. This is a special edition pendant designed in part by the Beverly Carter Foundation to help keep professionals, such as real estate agents, safe while visiting homes on the job.

It features an elegantly slim gold chain that extends down to a small locket that houses a secret personal safety device. If you are ever in danger, simply press the back panel of the locket twice and it will send out a message to five people whom you trust, warning them that you are in danger.

Best of all, thanks to a hidden GPS device, the warning message will also include your location so your trusted colleagues and companions can alert the authorities and send help. Thanks to its Bluetooth low energy consumption, you can wear the Invisawear Beverly Necklace safety device for up to two years without having to charge it.

It links to a free mobile app that works with both Apple and Android devices. Simply log into the app and choose your five closest people to whom you want the locket to send a message if you need help. You can even set it to dial 9-1-1 in an emergency.

Features:

  • A slim gold chain that extends into a small locket
  • A built-in GPS tracker
  • A double-click personal safety function
  • Links to a mobile app where you choose your five closest friends or family
  • A part of the proceeds goes to charity

Type: Pendant/necklace/locket

Colors: Rose gold

7. NFC Ring

The NFC Ring is an NFC-based ring that is smarter than what you might expect. It enables you to share information as quickly as by a fist-bump.

This device has two NFC tags on its upper and lower surfaces. You can store information on those tags and can share them with NFC enabled devices instantly.

The best usages of this ring are making payments, lock/unlock devices, lock/unlock doors and so forth. It is available in various colors and models to meet your choice of fashion.

Features:

  • NFC enabled smart ring supporting two tags
  • Share information to NFC supported devices by a bump
  • Make payments, lock/unlock doors and devices
  • Various colors and models for fashion need

Type: Ring

Colors: Horizon, Eclipse, Helios and 2 more

Note: There’s a similar alternative that looks great. You can see it on Amazon here.

8. Senstone

Senstone is a creative voice recording device that allows you to record voice notes on the move. The objective of this device is to help you to be more organized. It’s especially useful for those that are always busy.

It comes with a useful app on your smartphone that can sort recordings based on hashtags. You can integrate the notes with other apps and export them easily. Its aim is to make you less distracted while trying to increase productivity.

Unlike other jewelry on this page, it doesn’t come with activity tracking features. It is just a convenient voice recorder that can be worn as a clip, pendant or bracelet.

Note: Senstone is a crowdfunding project that has raised over 300k in Kickstarter and Indiegogo.

Features:

  • Creative voice recording device
  • Create audio notes on the go for productivity
  • Integration with a list of smartphone apps
  • Battery lasts up to 4 days

Type: Clip, Pendant, Bracelet

Colors: Twilight, Classy, Glace, Coal

Available On: KickStarter Indiegogo

9. Kate Spade New York Black Scallop Activity Tracker

Even luxury fashion houses have jumped onboard the fitness tracker trend. This stylish black design, brought to you by Kate Spade, is shaped like a simple wristwatch, making it both comfortable and easy to wear. However, unlike other wristwatch designs, this tracker does not feature a screen.

You will not be able to see the time or your stats simply by looking at the watch. Instead, you must synchronize it to a mobile app and view your stats from there.

Furthermore, this is a fairly basic sports tracker. You will only be able to track how many steps you’ve taken, your calories burned, and how well you have slept.

Compared to other trackers, this means you won’t be able to measure how many steps you’ve climbed, the duration of your workouts, or even your heartbeat. This is disappointing considering how attractive this option is.

Additionally, some buyers have reported that the Black Scallop isn’t the most accurate in its readings. One user noted that it’s not capable of distinguishing low and high-energy workouts, meaning that it will give the same calorie reading for a slow walk as an intense run.

Nonetheless, if you are new to fitness trackers, the Kate Spade Black Scallop Activity Tracker is a wonderful introduction and offers the two capabilities most people look for.

Features:

  • A sleek rubber wristwatch design
  • A golden top ring
  • Steps, calories, and sleep tracking
  • A necessary mobile app

Type:Wristwatch/wristband

Colors: Black and gold

10. Joule Earring Backing

The Joule Earring Backing might just be the smartest jewelry we’ve included. This product is not out yet in the market but the manufacturer is taking preorders. It pairs with any earings you like and fits pretty well with little extra bulk too. It is light-weight too, weighing in at just 1.5g and measuring just 18mm in diameter.

This smart wear seems to promise a high level of activity tracking. You will be able to monitor heart rate on a continuous basis and track other activities like steps and calories burned. You can measure your activity level using this tracker and make an understanding of your overall health.

The key thing about the Joule Earring Backing is that you are not making any type of compromisation on your style. The backing will stay hidden behind your ear while doing its job as it should.

Features:

  • Universal design, pairs with any earring
  • Continuous heart rate tracking
  • Activity tracking and level measurement
  • Battery lasts up to 1 day on a full charge

Type: Earring Backing

Colors: Silver

Available On: Joule

11. Fitbit Flex 2 Accessory Bangle

The Fitbit Flex 2 is a lightweight sports activity tracker that continues to work throughout the day and night, as long as you are wearing it. It uses a simple yet chic display consisting of five LED lights and can be worn as a bangle or, you can mix things up with other accessories to turn it into a wristband or a pendant.

The Fitbit Flex 2 bangle is completely waterproof, so you can wear it in the pool to track your laps and the duration of your workout. It also uses a MEMS 3-axis accelerometer to track your calories burned, the duration of your exercises, your steps and distance traveled, and even how long and how well you sleep at night.

The only downside to the Fitbit Flex 2 is that it doesn’t include an altimeter or heart rate monitor, so you won’t be able to track the number of steps you climb throughout the day or your heartbeats.

When you receive phone calls, the Fitbit Flex 2 will even notify you by lighting up and vibrating if you’re in another room or the middle of an exercise. It lacks a screen though, so you will have to track all of its data using the Apple/Android compatible Fitbit app.

Features:

  • Adaptable waterproof design
  • Tracks laps in the pool
  • Tracks duration and distance traveled
  • Links all data to the Fitbit mobile app
  • Tracks sleep duration and quality throughout the night

Type: Bangle/wristband/pendant
Colors: 22k Rose gold plated
