in one of my previous stories, I don’t like being available to my phone notifications and want it the other way around. However, if I switch off the notifications and am using a smartwatch for only tracking sleep, steps and calories, it loses the “smarts” and becomes an expensive fitness tracker on my wrist.
Noise says that there’s a non-allergic coating so it doesn’t affect your skin but wearing it for long with sweat and dirt gathering under it could cause irritation on the skin. You might want to take it off and clean it and your skin frequently if you have sensitive skin.The Noise Luna Ring houses an optical heart rate sensor, a blood oxygen sensor, PPG sensors, a skin temperature sensor and a 3-axis accelerometer.
Coming to functionality, the Luna Ring can track sleep, calories burnt, heart rate, temperature and more. Starting with sleep tracking, it is accurate for the amount of time you’ve slept but the “time in bed” is inaccurate, in my experience.
