I Tested the World’s Cheapest Smart Ring—Is It Worth Even $5?

When you hear “smart ring,” what do you think? For most people, it’s a mystery. A smartwatch? Sure. But a smart ring? Today I tested what claims to be the world’s cheapest smart ring, priced at just $5, to see if it’s even remotely useful.

What Can a Smart Ring Do?

Before we get into it, here’s a quick overview of what smart rings generally promise:

  • Heart rate monitoring
  • Step tracking
  • Sleep tracking (duration, quality, sleep phases)
  • Distance traveled & calories burned
  • Body temperature tracking
  • Some advanced models even offer contactless payments, phone call notifications, and even remote control features for smart devices.

But this budget ring focuses only on the basics:

  • Heart rate monitoring
  • Activity tracking
  • Sleep tracking
  • Blood oxygen and blood sugar readings
  • Menstrual cycle tracking (yes, even at $5)

The Unboxing Experience

Inside the box:

  • The smart ring itself
  • A magnetic USB charger
  • A small manual that explains how to wear it (which is actually crucial for this device)

The ring needs to be worn on your index finger with the heart rate sensor facing inward. Oddly, it fit perfectly out of the box—despite there being no size option when ordering.

The App Integration

The ring syncs with an app called LeaAn Health, which tracks:

  • Heart rate and heart health trends
  • Sleep patterns (deep and light sleep)
  • Blood oxygen levels
  • Blood sugar levels
  • Step count, calories, and standing goals

Does It Actually Work?

What worked well:

  • Sleep tracking: Surprisingly accurate. It gave me detailed sleep data that matched my experience, even noting I had too much light sleep.
  • Heart rate monitoring: Consistent readings across the day.
  • Blood oxygen and blood sugar monitoring: These readings seemed reliable based on casual comparisons to other devices.

What didn’t work:

  • Step tracking: Wildly inaccurate. It underreported my activity by about 70% compared to a smartwatch.
  • Exercise tracking: Incorrect durations for running and walking.
  • Standing goal: Completely off. It recorded just 3 instances of standing up when I was on my feet frequently that day.

Build Quality & Comfort

The positives:

  • It’s lightweight and surprisingly comfortable.
  • Charges fast via a magnetic cable.
  • Fits well despite no sizing option.

The Verdict

While it handled sleep and heart rate tracking reasonably well, the step and exercise data were too inaccurate to make this a useful fitness tool. Roughly half of the advertised features either didn’t work or weren’t reliable.

For $5, it’s hard to be upset—but the reality is, you could spend just a little more on a smartwatch with far more functionality and accuracy.

This smartwatch in particular I would recommend WAY more than this: Cheapest Good SmartWatch (affiliate)

💰 I Tried the World’s Cheapest Smartwatch ($8?!) – Here’s What Happened

Ever wonder if you could stop being lazy and unhealthy without dropping hundreds of dollars? Turns out, you can—even if you’re broke.

Enter the world’s cheapest smartwatch. I paid around $8 for it (you can grab it now for about $20). When I got it, I expected a joke. But what I found actually shocked me.

📦 What’s in the box?

Simple and barebones:

  • The watch itself
  • A USB charger
  • A manual (I think? I didn’t really need it)

Setup was stupidly easy. Faster than some premium watches I’ve tried.

🩹 The Fitbit Killer?

Quick backstory: I used to own a Fitbit. It made my wrist glow red and irritated my skin, then broke way too early. So I assumed this $8 watch would be a disaster. Nope.

This thing is:

  • Way more comfortable than any watch I’ve worn
  • Fully adjustable with a soft, lightweight band
  • Better than even my normal everyday watch
  • No skin irritation at all, even after a week of wearing it daily

🖥 Apple Watch vibes… for $8?!

No, you can’t download apps like on an Apple Watch. But let’s be honest—how many Apple Watch features are you REALLY using anyway?

This is like the stripped-down version of a smartwatch, but it nails the essentials:

  • Tons of default & customizable watch faces (hundreds available via the free app)
  • Display of steps, weather, calories, miles walked, and more—all right on the home screen

Responsiveness

Swipe in any direction, use the side dial, and everything just works. The response speed? Feels like an Apple Watch. I’m serious. ZERO glitches.

🔥 Feature Bomb

This is where it gets crazy. Here’s just a fraction of what this $8-$20 watch can do:
✅ Step tracking
✅ Distance + calorie counting
✅ Heart rate & blood oxygen monitoring
✅ Stress level tracking
✅ Automatic sleep tracker
✅ Alexa integration
✅ Music control
✅ Phone call support
✅ Flashlight
✅ Full phone notifications (texts, Snapchats, etc.)
✅ Reminders, timers, alarms
✅ Weather forecast
✅ Water drinking plan
✅ Weight tracking
✅ Blood sugar management
✅ Menstrual cycle tracking
✅ V2 Max (I don’t even know what that is)
…and more—all for free, inside the app.

For the price? Mind-blowing.

🧪 Does it actually work though?

I put it to the test. Steps? Accurate. Heart rate and stress level? Matched what I was feeling and doing every time. Sleep tracker? Worked like a charm.

Nothing has glitched or miscalculated after a week of daily use.

🔋 Battery Life Test

I charged it ONCE when I first unboxed it. After 7 full days of wearing it off and on? Still at 78%. WHAT?!
That means you can track your sleep AND your daily steps without worrying about charging it at night or halfway through your day.

🏃 Workout Test

Set a 5-minute outdoor run goal → Ran → Came back → Boom, stats displayed instantly. The app even recommended a 7-hour recovery period based on my data (rude but probably true).

The Verdict

I love this watch. It’s simple, comfortable, and wildly overdelivers for the price. I usually don’t stick with smartwatches because they’re overpriced—but this one? No-brainer. It works, it’s dirt cheap, and it doesn’t come with all the bloat that makes expensive watches annoying.

Honestly, even if this thing cost $100+ I’d still be impressed. At around $20? This is a steal.
