Its incredibly comfortable, resistant to scratches, and does a great job with heart rate tracking.
Battery life is average, and the limited size and finish options might be a dealbreaker for some.
The Zepp app is clean and functional, but lacks the polish of higher-end alternatives.
The app is very nice, the battery life is solid, and its a great companion for workouts.
Smart rings have finally gone mainstream.
But with so many options on the market, choosing the right one isnt easy.
Weve tested most of thebest smart ringsyou can buy in 2025, but direct comparisons arent always straightforward.
One is affordable and practical, the other more premium.
But which one is right for you?
At first glance, the Amazfit Helio Ring seems like the obvious choice for budget-conscious buyers.
Theyre subtle but worth noting.
But honestly, that might not be a dealbreaker.
In my experience, the EDA readings felt more like a nice-to-have than a must-have.
Battery life is trickier to compare.
Both rings charge via a small plinth-style dock, making recharging quick and easy.
After all, theres no screen on a smart ring.
The Ultrahuman app has the upper hand in design, with a sleek, modern, almost futuristic aesthetic.
Each app brings its own unique tracking features.
Zepp includes stress tracking and PAI (personal physiological activity indicator), a metric for overall fitness.
Ultrahuman also tracks stress, but pulls from a different set of data points.
That said, Amazfits recovery tracking is still solid.
In terms of accuracy, both rings perform very similarly.
Where Amazfit really stands out is its ecosystem.
Theyre minimalist, sleek, and unobtrusive.
One practical advantage of the Amazfit Helio Ring?
It seemed less prone to scratching.
One thing I can say for certain: Matte black is not a good idea.
Comfort-wise, these are the two best smart rings Ive tested.
Both are so light and ergonomic that I frequently forgot I was even wearing them.
As for dimensions, theyre almost the same.
Its significantly cheaper and covers all the same core features as the Ultrahuman Ring Air.
But price isnt everything.
Whether thats worth the extra money depends on what you value most.
For some, those refinements will be worth it.
For others, the Amazfit Helio Ring delivers everything they need at a much lower price.
That said, the Amazfit Helio Ring delivers a lot for significantly less money.
If youre on a budget, this is the easy pick.
