Best Smart Rings of 2025: We Tested The Top 3 To See Which One’s Actually Worth It
Smart Rings Are Exploding in 2025 — But Do They Actually Work?
Fitness trackers have come a long way. But bulky watches are out — and sleek, barely-noticeable smart rings are dominating the wearable health space. They claim to track sleep, vitals, recovery, even blood pressure — all from your finger. Sounds impressive. But most fall flat when you actually test them.
That’s exactly why we bought the 3 most hyped smart rings right now — the Herzp1 Smart Ring, the Oura Ring Gen 3, and the Ultrahuman Ring Air — and ran them head-to-head for one full week. The results shocked us.
What We Actually Tested
We weren’t just looking at fancy features. We tracked each ring based on 5 key metrics that actually matter to real users:
We honestly didn’t expect much from the Herzp1 Smart Ring. At $49, it’s a fraction of the price of Oura and Ultrahuman. But after 7 days of tracking — it kept pace with (and in some cases outperformed) both competitors.
The standout? Blood Pressure Monitoring — something neither Oura nor Ultrahuman even offer. Combine that with accurate sleep tracking, heart rate, blood oxygen (SpO2), body temp, and a full 7-day battery, and you get an insane amount of biometric data for under $50.
Is the app as polished as Oura? No. Is it as “luxury” feeling? Not quite. But for actual core health tracking — Herzp1 delivered where it counted.
Why The Premium Options Struggled
Oura is still the most recognized name in smart rings — and for good reason. The ring design is premium, lightweight, and very comfortable. Its app is polished, easy to navigate, and offers plenty of detailed insights, especially around sleep and recovery.
That said, the Oura Ring does have some downsides. It lacks blood pressure monitoring entirely, doesn’t include SpO2 readings in real time, and most of its advanced features require a monthly subscription on top of the $299 purchase price.
It’s a great smart ring if you care mostly about sleep tracking and don’t mind paying for premium software — but compared to Herzp1, it falls short in terms of overall biometrics and value for money.
The Ultrahuman Ring Air focuses heavily on metabolic health, movement, and recovery insights. Its ring is extremely light and comfortable for 24/7 wear, and the app does a good job of breaking down sleep, movement, and metabolic scoring.
However, while it excels in comfort, it still lacks some of the more advanced vitals tracking — like blood pressure, real-time oxygen saturation, or temperature trends beyond basic measurements. At $349, it’s one of the most expensive options, and honestly, its data depth doesn’t justify the premium price compared to what Herzp1 offers at a fraction of the cost.

Our Final Verdict
If you’re looking for a smart ring that tracks real health data — not just basic steps and sleep — the Herzp1 Smart Ring is hands down the best value in 2025. It’s the only ring under $50 that delivers full biometric tracking, including blood pressure, heart rate, SpO2, sleep, and temperature — without forcing you into expensive subscriptions or overpriced premiums. For actual health tracking that matters, Herzp1 simply delivers more for less.
