The R11 Ultra is a new smart ring that can record various health metrics but also show certain information on a small display. The wearable is waterproof and advertised with various health features.

Rollme is now offering a new wearable called the R11 Ultra in its own online store. Unsurprisingly, this is a smart ring that supposedly offers extensive features and is available in three color variants and multiple sizes for a price of $50. That said, prospective buyers should look into the shipping conditions and potential import fees.

Rollme specifically promotes two features of the R11 Ultra, namely the built-in display and the possibility to use it as an input device. More specifically, the small display can show the battery state of charge, heart rate, current time or the number of steps taken. Additionally, the ring can also be used to trigger the smartphone camera with gestures, and it can even scroll through TikTok. The model can also be used as a tally counter.

In terms of sensors, Rollme’s new wearable isn’t exactly groundbreaking. It optically measures heart rate and blood oxygen saturation, and the stress level can also be determined. According to the manufacturer, sleep quality and duration can also be tracked and then analyzed. Activity tracking is possible as well and incorporates the data such as heart rate and number of steps.

Therefore, the smart ring can calculate the approximate distance covered during runs, even though the R11 Ultra does not sport a GPS module for more precise location tracking. Furthermore, the ring is water resistant up to 5 ATM and has a battery life of up to seven days on a full charge. It can last even longer in standby and can be charged on a magnetic charging base.
