Smart rings are the new wearable craze with multiple makers launching competing models, but most of them are fairly pricey – for example, a Galaxy Ring is $400, a gen 3 Oura Ring (which is three years old now) still goes for $300. But smart rings don’t have to be expensive as Rollme’s new model demonstrates.
Rollme R3 smart ring in Black, Silver and Gold
The Rollme R3 can be yours for just $90. There are technically two models that precede it, but Rollme launched the R1 in January of this year and the R2 came in March. The R1 is $100 and the R2 is $90.
The R3 comes in several sizes, from 7 to 12, and can be had with a black, silver or gold exterior. Said exterior is made out of titanium, while the inside is a hypoallergenic epoxy resin, which won’t irritate your skin.
Rollme R3 build • Charging case
The ring has a 17.5mAh battery built-in, which should last 10 days of regular usage. It comes with a small recharging case, which will extend the total wearing time to 60 days.
The ring has a heart rate sensor with IR, red and green LEDs, which can measure your heart rate, heart rate variability and blood oxygen saturation. It can use this to track your health and exercise with multiple sports modes (walking, running, cycling, etc.).
Health and exercise tracking
The ring is rated for 5 ATM water resistance and you can take it swimming and even snorkeling, says Rollme. And at the end of your day, the R3 ring will monitor your sleep with deep and light sleep detection.

The ring has one more use case – gesture control. You can set the double tap gesture to play/pause audio, take a photo with your phone, start recording video or, if you’re reading an ebook, flip to the next page.

You can find the Rollme R3 smart ring over on the company’s official site.
