Alza started selling its own smart ring. The WOWME Ring is made of titanium, lasts up to 10 days, and requires no subscription

Smart rings are often an expensive toy – for an Oura Ring or Galaxy Ring, you’ll pay several times the price of a regular fitness tracker, and with Oura, you also pay a subscription. Alza now offers a much cheaper alternative. Under its WOWME brand, which until now mainly produced smartwatches and accessories for them, it has started selling the WOWME Ring for 2,999 CZK. It tracks sleep, heart rate, and stress, and you don’t have to pay a single extra crown to have all features available.

Titanium ring tracks sleep, heart rate, and stress

The WOWME Ring is made of titanium with a DLC coating, which is designed to increase scratch resistance. You can choose from two colors, Shadow Black and matte Silver Frost, and sizes 6–13. However, size ten is missing for the silver one for some reason.

The ring automatically records sleep duration and phases, from which the application calculates your sleep score. It also measures heart rate, its variability (HRV), blood oxygen saturation, stress estimation, and skin temperature changes. From the measured data, it also derives a body energy indicator, i.e., how well you have regenerated. Step and calorie counting, menstrual cycle tracking, and 5 ATM water resistance are also included, so you don’t have to take it off even when swimming.

Alza states a battery life of up to 10 days, or about a week with typical use. Charging takes about two hours, but it’s important to note that the case does not have its own battery. Therefore, if it’s not connected to a power source via USB-C, it won’t supply power to the ring.

The app comes from China

The ring connects to your phone via the JCRingPro app, which is available for both Android and iOS and supports Czech. It sends data to Apple Health and Health Connect and reportedly also works with Strava. However, it is not directly Alza’s software – according to the App Store, the app is developed by the Chinese company Guangdong Youhong Medical Technology.

Verify your size with a kit for 99 CZK

When choosing a ring, its size can be the main stumbling block. It shouldn’t pinch you, but if it’s too loose, the sensors won’t make contact with your skin, and the measurement results will be inaccurate. Following the example of more well-known smart ring manufacturers, Alza therefore also sells the WOWME Ring Sizing Kit for 99 CZK. The kit contains eight trial rings in sizes 6 to 13 according to the American standard, so you don’t have to measure your finger circumference. You can return the kit within 14 days.

Alza recommends wearing the ring on the index finger of your non-dominant hand, or on the middle or ring finger, with the sensors facing the underside of the finger. Once you know your size, you can directly order the silver or black variant.
