@totokwa: Smart ring na may screen? This is the Aolon Gen4 Smart Ring — ultra thin at just 2.5mm and 2.9g, yet it shows your heart rate, steps, sleep, blood oxygen, and time on its LCD screen. It’s IP68 waterproof, works as a camera remote, and lasts up to 7 days with the charging case. If you want a compact fitness tracker you can wear as a ring, this is it. #aolon #smartring #totokwa #wearabletech
