femometer Smart Ring Gen2 Smart Ring - Sleep, Heart Rate & Cycle Monitoring: Continuous heart rate monitoring
But wait, there’s more. Feeling stressed? The ring’s got your back with stress monitoring that nudges you when you’re wound tighter than a spring. And for those days when you’re more couch potato than gym bunny, the step and calorie monitoring gently (or not so gently) reminds you to get moving. Oh, and let’s not forget the advanced BBT technology—taking over 1,400 temperature readings while you snooze to nail those cycle predictions and ovulation detection with scary accuracy.
All this tech comes wrapped in a sleek, comfy design that weighs about as much as a couple of paperclips (just 3.3g, to be exact) and can handle a dip up to 100m. With battery life that stretches up to a week and a free Femometer app to tie it all together, it’s like having a health guru with you 24/7—minus the judgmental looks.
