If you’d told me two years ago that I’d ditch my smartwatch for a tiny titanium ring, I’d have laughed. But here I am — a full-on smart ring convert.
I first got into wearables to improve my sleep, but I hated wearing something bulky at night. When smart rings started trending in 2025, I tested five of the most talked-about models to see which ones actually work and which are just hype.
After months of testing, here’s my honest take on the best smart rings of 2025, what they’re best for, and whether they’re really worth your money.
💍 1. Oura Ring Gen 4 — Still the King of Sleep & Stress Tracking
When I first slipped on the Oura Ring Gen 4, it immediately felt premium — like a piece of jewelry, not a gadget.
What it does: It tracks your heart rate, sleep stages, and recovery with incredible accuracy. I compared its data to my Apple Watch Ultra, and Oura’s insights were actually more consistent over time.
What impressed me most was the Readiness Score, which predicts how well you’ll perform that day based on your sleep and recovery. It helped me avoid overtraining at the gym.
💡 Tip: If you care about sleep and stress, Oura is still unmatched. I charge it once a week and forget it’s even there.

⚡ 2. Ultrahuman Ring Air — The Biohacker’s Dream
This one is for data lovers. I got the Ultrahuman Ring Air after hearing biohackers rave about it — and they weren’t exaggerating.
What it does: Beyond heart rate and steps, it syncs with glucose monitors to show how your diet affects your energy levels in real time. When I had a high-carb lunch, my metabolic score tanked. That kind of feedback changed how I eat.
Why it matters: It’s not just tracking; it’s teaching you how your body reacts to food, stress, and sleep. If you’re into performance, this is gold.
💡 Tip: Pair it with Ultrahuman’s app to unlock nutrition coaching and AI-driven insights.

💸 3. RingConn Smart Ring — Premium Feel, Affordable Price
When I first saw the price tag — under $300, no subscription fees — I thought it had to be limited. But RingConn completely surprised me.
What RingConn Gen 2 does: It tracks heart rate, steps, SpO₂, and sleep basics. The design feels solid, and the app interface is simple.
Why I recommend it: It’s perfect if you’re curious about smart rings but don’t want to spend $400+. I even wore it while swimming, and it held up perfectly.
ROI Example: I noticed how my deep sleep improved after cutting caffeine — something I wouldn’t have realized without the data.
💡 Tip: Great first smart ring for beginners. Save your premium upgrade for later.

🌸 4. Evie Smart Ring — The Wellness Device Built for Women
As a guy, I didn’t personally use the Evie full-time, but my partner did — and her feedback was glowing.
What it does: It’s designed for women’s health, tracking cycles, stress, and recovery. The dashboard displays hormone insights and energy balance in a way that’s easy to understand.
Why it stands out: It’s FDA-cleared for accuracy, which gives it a level of trust missing in many wearables.
Her favorite part? The rose gold version looks like fine jewelry — she wears it even when she’s not tracking.
💡 Tip: For women looking to monitor health discreetly, Evie is a great lifestyle-tech balance.

This one blew my mind. Cnick smart ring isn’t just about fitness — it’s about convenience.

I first tried it at a coffee shop, and people actually stared — in a good way. It’s waterproof, doesn’t need charging, and feels surprisingly natural to use.
