Use this ring knife to open boxes and kill zombies

NEWS – I’m just kidding, the blade on this ring knife isn’t long enough to kill a zombie. At least I don’t think so. Is this a useful knife? Highly doubtful. But this weaponized stainless steel ring will get a conversation started the first time you press the button on the side and the spring loaded blade flips open. And before you say something about TSA. Just don’t. Use common sense and don’t wear something like this to the airport. Duh. Want to learn more or buy one for $24.99 from Haddishop or way cheaper on from AliExpress.

Motiv Smart Ring review

REVIEW – Over the years I’ve reviewed a LOT of fitness trackers. The vast majority of them have been trackers that clip to a belt or ones that you wear on your wrist like a watch. Only recently have we started to see fitness trackers that are small enough to fit on your finger like the ŌURA Ring that I reviewed over a year ago. I loved the idea of a finger wearable fitness tracker, but the original version of the  ŌURA Ring was just too large and uncomfortable for me to wear 24/7. Another smart ring fitness tracker that was on my gadget radar during that time was the Motiv Smart Ring but they ignored my requests to review one. Fast forward to a month ago when I was looking for gadgets to gift to myself for Christmas. The gifts that I ended up buying were an Apple MacBook Air, a 2018 11-inch iPad Pro, a DJI OSMO Pocket camera, and a Motiv Smart Ring. I ended up returning all of those gifts except for the Motiv Smart Ring, so I guess you can say that I like it. Let’s take a closer look.

What is it?

The Motiv Smart Ring is a truly ring sized fitness tracker that you wear on your finger 24/7 to track your activity, steps, sleep, and heart rate.

What’s in the box?

  • Motiv Smart Ring
  • USB magnetic charging dock

Design and features

Anyone who sees you wearing this smart ring will have no idea that it’s nothing other than a regular piece of jewelry as it takes a close look to see the electronics. First of all the ring has a titanium shell with a scratch resistant coating and is available in silver, rose gold, or black. I bought the black version that has a very subtle brushed matte finish.

The ring is ultra comfortable because it’s lightweight and there’s nothing noticeable that presses against your finger when you’re wearing it. You can see the flat part of the ring inside the medical grade plastic band which is where the steel and gold plated electronic contacts are located, but you don’t really feel it while wearing the ring.

When you order a Motiv ring, you’ll be sent a box of 7 plastic sizer rings that range from size 6 up to size 12. You’re instructed to wear the best fitting ring for at least 24hrs before you submit your ring order. Not that anyone cares, but I ended up with size 7 for my ring finger on my right hand.

The actual working smart ring fit identical to the sizer ring, so my delivered Motiv ring fit perfectly which is what you’ll want because you’re able to wear this ring 24/7 because it’s waterproof to 165 feet. That means you can swim with it, shower with it, workout with it, wash your hands with it, etc.

But before you can start using the ring, you’ll need to charge it. Luckily, that’s a simple and quick task. The ring comes with a magnetic charger that plugs into a USB port and quick charges the ring in about 90 minutes. You’ll also be happy to know that the Motiv Smart Ring has a 3-day battery life so you won’t have to charge it every day.

While the ring is charging, a small LED hidden in a strip on the ring will glow red while charging and will glow green when fully charged. Once in a while, you’ll also notice that the LED on the ring is flashing blue which means it’s syncing data with your phone. Note, that you don’t have to have your phone always with you to make sure you don’t lose your fitness data. The Motiv Ring has enough onboard memory to keep your stats safe for up to 3 days.

Motiv app


The Motiv app is available for iOS and Android. I have been using the Android version of the app with my Pixel 2 XL. The app’s interface is easy to understand and navigate. The dashboard screen shows your accumulated stats for the day which include how many hours you slept the night before, your active minutes for the day, steps for the day, miles traveled, calories burned, last heart rate, and a scrolling list of your activities.

The settings screen shows the current battery status and lets you customize your profile info and link to your Google Fit account.



The Motiv Ring doesn’t take a heart rate reading every minute like the VivaLNK Vital Scout continuous wellness monitor wearable patch that I reviewed recently, but to help save battery life, it senses when you are active.

We optimized our system to sample heart rate when it matters most, in order to maximize battery life. When we sense step activity, the heart rate sensor activates. For all those times you’re not generating steps, we check your heart rate every few minutes and if your heart rate is elevated, the Motiv Ring will engage the sensor to track continuously those times you are active.

As for step tracking, I found to be within 100 or so steps of the Google Fit app on my phone.

What I like

  • Comfortable to wear 24/7
  • 3-day battery life and quick charging

What needs to be improved

  • Better heart rate graphs with the time of day so you can see when the rates were elevated or lowest
  • Add recovery rate
  • Better sleep tracking graphs that show the times during the night when you were awake, etc
  • I’d like to see contactless payment features added

Final thoughts

Right now, the Motiv Ring is my favorite fitness tracking wearable. When I put it on I forget about it because it is comfortable to wear all day and while sleeping. I only take it off when I put lotion on my hands or when I need to charge it. The only downside to the Motiv Ring is the price, but I’m hoping they add more features to it to justify the expense. They already have a 2-step security feature for iOS and you can request access to the open beta for Android if you want to test it – this is something I haven’t done yet.

There has also been talk of a contactless payment feature later this year that uses your heart rate to identify you. That’s a feature I’d love to have so I don’t have to take my phone out of my pocket when buying something. Unfortunately, it won’t come to existing rings and will require that I buy a new one. But even as it is now, I’m still a fan of this ring. So much so that I bought one for myself.

Price: $199.99

Jewelry that helps you find your way

NEWS – This awesome looking pendant from Swiss jeweler Meister is an actual working compass that folds down into a wearable piece of art. Made of titanium and gold, Meister offers three wearable gadgets that include two types of compasses and one sundial. I’m not sure how useful this compass pendant really is, but you have to admit that it looks pretty darn cool. But don’t get your wallet out just yet because when I tell you how much this wearable compass costs, you probably won’t care if you get lost. Ready for it? $2520 from Thorn Jewelry in the UK. I think I’ll stay south of this one.

The bracelet that lets you keep count over your life

NEWS – Do you need to count things during your day?  How many times (or minutes) you take for a breathing break, your golf strokes?  How many ounces of water you drink, or even how many rows you’ve knitted?  If you need to count anything during your day, you can use the Life Tree Abacus Counting Bracelet to keep track.  The bracelets have a double row with nine beads each.  The beads are 8 and 10 mm and are in two colors.

Each time you need to increment your count, simply slide the rubber bands past the appropriate bead.  The bracelet shown here is showing 21.  You can count up to 99 with the Life Tree bracelet.

The bracelets are available in three sizes to best fit your wrist.  Each one is handmade, so you need to allow 3-5 days for the artist to craft your bracelet before shipping.  An artisan shop named Jill’s Beaded Knit Bits makes the Life Tree Abacus Counting Bracelet in several color combinations.  Each bracelet is $26.95.  See them all at Jill’s Beaded Knit Bits shop at Amazon.

Wear the solar system on your wrist

NEWS – I’m fascinated by jewelry and little knickknacks representing the solar system.  I recently found a bracelet with stone beads that shows the sun and all the planets (plus Pluto, too if you want).  The Solar System Stone Bracelet is the perfect gift for the astronomers – or even astrologists if that’s your wont.

The bracelet has semi-precious stones for the planets.  There’s no sun for this bracelet, but there are blue sandstone beads to represent the universe, obsidian black holes, and metal stars and spacer beads.  The bracelet is available in 6.9″ or 7.4″ fixed-lengths (seen in the top image) or as an adjustable bracelet (second image).  All three styles are available with or without Pluto.

The Solar System Stone Bracelet is normally $39.99, but it’s available right now for $19.00.  All sizes and styles are the same price.  Check them out at the GiftTheGalaxy website.

And just so you know, they say they donate to the Planetary Society for each purchase made, to help advance space science and exploration.  There’s no mention of what they plan to do for the Space Force…  😉
