Rollme R1 appears as affordable smart health-tracking ring

The Rollme R1 is said to be able to track your exercise, stress level and sleep quality; the product page says rest is automatically logged between 10 PM and 8 AM, suggesting this is a relatively basic sleep monitoring tool. Health metrics like your heart rate and HRV are checked every half hour, or you can manually trigger a measurement. Other alleged features include body temperature and blood oxygen saturation logging. You can view data collected by the wearable in an accompanying app, with Rollme assuring customers there is no subscription fee. The device has a 23 mAh battery, supposedly allowing it to run for up to seven days on a single charge. The gadget comes with a wireless charging case with a 400 mAh battery, allowing you to recharge the device up to 20 times.

The ring has a nano-ceramic body with a stainless steel lining and is rated as IP68 water and dustproof. You can choose from four sizes between 16 and 22 and two colors, black or white. The Rollme R1 Health Smart Ring starts at the discounted price of $99, $130.99 lower than its supposed $229.99 retail price. The website suggests that the company ships to the US, the UK, Germany and China. However, it is worth noting a couple of possible red flags: the refund policy page does not provide a returns address, and a seemingly personal email address is provided for customer service. Instead, we recommend considering a model like the Ultrahuman Ring AIR.
