Smart Ring - Sleep, Heart Rate & Cycle Monitoring
Anna B.
Lille
April 15, 2025
First impression this little ring punches above its weight I was skeptical but it's become a handy sidekick for keeping an eye on my health as a pragmatist I appreciate things that just work and this does mostly it tracks my sleep and gives me insights without being intrusive the alarm wakes me up gently which is a nice touch and the cycle predictions are surprisingly accurate for my needs as a single woman in my forties living in Lille it fits well with my active lifestyle cycling and scooting around but it's not perfect had some hiccups with the app setup and it feels a bit pricey for what it does overall though I'd recommend it to friends looking for a simple health tracker
- Pros: The delivery was quick and the ring is super light and comfy to wear all day and night I like that it seems to track my sleep stages and heart rate without me noticing it and the battery lasts ages so I dont have to charge it often
- Cons: It took a bit to get used to wearing something all the time and the sizing was tricky at first had to use the kit to find the right fit and sometimes the app seems a bit confusing for a beginner like me
