The smartwatch got smaller. Then the smart ring arrived. Now Rogbid has released something that splits the difference and costs less than a nice dinner: the Fusion, a hybrid device that looks like someone shrunk a fitness tracker and stuck it on a ring band. For fifty dollars, you get a legitimate OLED display, actual health sensors, and the ability to wear your technology on whichever body part feels right that day.
This is more than just miniaturization for the sake of novelty. The Fusion measures 20.6 x 21 x 8.2mm and weighs about as much as three quarters stacked together, yet it monitors heart rate, tracks sleep, measures blood oxygen levels, and survives underwater thanks to 5ATM water resistance. Rogbid includes both a finger-sized adjustable strap and a wrist band, turning the device into whatever you need depending on your outfit, activity, or tolerance for questions from strangers. Battery life hits five days with regular use, which means this tiny screen actually pulls its weight between charges.
Designer: Rogbid
You have to give Rogbid credit for seeing Casio’s G-Shock ring sell out and thinking, “we can do that, but with actual tech inside.” That Casio piece was pure nostalgia, a fun gimmick that proved a market existed for finger-watches. Rogbid’s move feels like the logical, if slightly unhinged, next step: taking the novelty and injecting actual utility.
We’re talking over 100 sports modes, which is a software problem I don’t even want to think about navigating on a half-inch screen. But the hardware is there: an optical heart rate sensor, blood oxygen monitoring, and all the usual motion tracking. They even added prayer time reminders and a “couple interaction mode” for sharing codes, which feels like they just kept adding features from a hat until they ran out of room. It’s the kind of feature creep that’s almost admirable in its audacity, especially when most competitors are still trying to get basic step counting right in the ring form factor.
This whole thing is a fascinating gamble on what people want from a smart ring. The entire appeal of the Oura and its competitors is their subtlety; they disappear into your daily life. The Fusion, however, plants a glowing OLED screen right on your knuckle and demands attention. It’s a complete rejection of the minimalist aesthetic that defined the category. Maybe that’s the point. For fifty bucks, Rogbid isn’t trying to compete with the thousand-dollar jewelry pieces. They’re creating an entirely new, wonderfully weird sub-category of wearable that’s too cheap and too interesting to ignore.
