Generally, smart rings are worn around the finger silently doing all the tracking while you can see stats captured in the app. The Rollme R11 Ultra adds a twist in that it has a display on the side, as well as a touch-sensitive interface.
Referencing the ring’s display, you can see stats like the time, steps, heart rate, and battery level without needing your phone. It continues to track other metrics in the background through its advanced chip and sensors, including deep sleep stage analysis, continuous heart rate tracking, and blood oxygen saturation (SpO2) measurement.
Finished with a durable stainless-steel body that is resistant to wear and tear, the slim ring measures just 8mm in width and is 2.5mm thin, weighing just 4 grams. It is 5ATM water resistant so you can wear it all day, including while showering and swimming.
The Rollme R11 Ultra supports multiple sports modes, including walking, running, cycling, and swimming. For each activity, it tracks real-time heart rate, step count, distance, calories burned, and workout duration. It also offers intuitive gesture controls so you can do things like interact with apps like TikTok, e-books, music, and camera functions, as well as certain motion-controlled games using simple hand movements.
The free companion app is compatible with both iOS and Android and can be used to do things like set personal goals and receive activity reminders as well. It runs for up to 15 days per charge and comes with a charging cable and dock.
The Rollme R11 Ultra is available for US$50 and comes in gold, silver, or black and in six sizes from 8 through 13.
