If you want fitness tracking without a bulky watch, the AMOVAN R09+ Smart Ring is built for comfortable, all-day wear and quick check-ins in the QRing app. It tracks key wellness metrics like heart rate, blood oxygen, body temperature, sleep, steps, distance, time, and calories—then organizes your data into daily, weekly, and monthly views.

Under the hood, AMOVAN highlights a Bluetooth 5.2 dual-mode chip and multiple sensors designed for stable pairing and reliable motion recognition, including detection of 15 preset actions. Data transmission is encrypted to help protect privacy.

For workouts, you get 100+ sports modes and automatic tracking basics (steps, distance, time, and calorie consumption) so you can keep tabs on trends without paying a monthly fee. The ring is marketed as water resistant for daily use like handwashing, showering, and shallow swimming (the listing mentions 5ATM and also shows an IPX67 rating in specs), so check the rating details on your product page if water use is a priority.
