Great ring for sleep and daily use

[This review was collected as part of a promotion.] I’ve been using the ring for about two months now, and overall I’m very happy with it. The ring hasn’t discolored at all and still looks like new. It’s very comfortable to wear, even while sleeping or during workouts. I use it regularly for strength training, and it never gets in the way or feels uncomfortable.
It’s especially great for sleep tracking — very accurate and insightful. One downside is that you can’t see things like calorie burn in real time; you only get the data afterward. Also, the battery life is a bit shorter than advertised. I usually get about 4 to 5 days per charge. Still, compared to a smartwatch, this is already a big improvement for me.
All in all, I’m really satisfied with this ring and would definitely recommend it for anyone looking to track sleep and activity in a more subtle way.

[This review was collected as part of a promotion.] I love my ring. It helped me so much. I’m still post partum but especially during pregnancy it was amazing. I loved seeeing how pregnancy affected my sleep and stress and even temp. And now I can see how it’s changed after birth.

Great for Work/Life Balance

[This review was collected as part of a promotion.] I bought this three months ago and this has completely changed the way I live my life. It’s given me insights on my sleep habits, caffeine intake, and most importantly, activity to achieve a healthy balance. The app’s curated sleep goals actually help me feel better throughout the day when achieved. The activity levels and movement goals have helped me maintain an active lifestyle while working a rotating day and night shift schedule as a nurse and still feel refreshed to be present for my family. I’m loving this ring so far! 10/10

Great for sleep!

[This review was collected as part of a promotion.] I bought my ring in June and I’ve been primarily using it to track my sleep! I find it gives very accurate readings and is really good at giving me suggestions and graphing my data. The only reason I gave it four instead of five is that the ring scratches super easily. I have the gold and a lot of it is basically silver at this point. I don’t wear rings around it at all so it’s not rubbing on anything. The battery is okay, I charge it probably every 3 to 4 days. I was hopeful it was going to last longer. Also, often when I go into the app, it takes quite a while to load my data and I have to refresh it quite a few times.
