My friend and I were sipping flat whites last week when I spotted a chunky silver ring on her finger. No, not an engagement ring; not an Oura Ring; but the budget prxxhri smart ring, now down to $53.99 at Amazon.

Now, I'm the biggest advocate of my Oura Ring. If you'll allow me, I'll gladly talk your ear off about how it's the best sleep tracker you can buy (honestly, I'm a hoot at a party). But comparing my pricier Oura Ring 4 with my friend's Amazon bargain, I was dumbfounded by the surface-level likeness between the two.

If you're on a budget and looking for a subscription-free Oura Ring alternative to help you track and improve your sleep, I'd certainly recommend it. But don't wait around, as right now the prxxhri Smart Health Ring is at an all-time lowest price in the Memorial Day sales. Here's how it works, along with how it compares to the Oura...

What is the prxxhi Oura Ring alternative?

The prxxhri ring is essentially a dupe of the world's most popular smart ring, the Oura. It has a titanium outer shell with sensors sitting on the inside of the ring, collecting health data from your finger.

As Oura Ring alternatives go, the prxxhri is one of the good ones, sporting hundreds of positive reviews on Amazon. Customers say it's comfortable to wear overnight and provides useful sleep insights.

Trust me, I've combed the reviews section of many a budget smart ring and there's not many that get such praise, if any praise at all.

The prxxhri ring is available in six size options (there's detailed size chart on Amazon to help you find the right fit) and three colorways — silver, black, and rose gold.

It's compatible with iOS and android, and lined with sleep tracking sensors that deliver data about your sleep duration, sleep cycles, and overnight heart rate, as well as awarding you an overall sleep quality score. By day, it tracks your steps, calories, and exercise activities.

How does the sleep tracking compare to the Oura Ring?

The main reason you'd buy the prxxhri ring over the Oura Ring is because it's more affordable and does away with subscription fees (yay). But for that affordability, you must makes sacrifices in terms of sleep functionality.

While the prxxhri smart ring delivers basic sleep tracking data, it doesn't go far beyond sleep duration and sleep stages. By comparison, Oura goes into much more depth adding metrics like sleep latency (how long it takes you to fall asleep), sleep efficiency (a metric gauging how long you spent asleep compared to how long you spent in bed), and a sleep debt log to its sleep tracking offering.

The prxxhri smart ring does measure your heart rate but it does so every 30 minutes, whereas Oura offers constant heart rate tracking, as well as heart rate variability (this can tell you a lot about how well your body is recovering), average oxygen saturation, and breathing regularity — all useful biometrics to be aware of if you're concerned about breathing disorders like sleep apnea.

Battery life is also better at Oura. You can expect the prxxhri ring to last two to three nights on a single charge; whereas Oura will power through six nights before needing its charging dock.
