    • Amazing!
Style: Heritage Color: Silver Size: 8
I love this ring! I purchased a few other knock off, cheap brands to save money but ultimately returned them because the tracking was completely off. This ring does everything. It accurately tracks my sleep (can also detect sleep apnea), oxygen levels, steps, knows when I take a nap, when I truly go to bed, when I do housework, measures my stress levels, heart rate, and after a month, it calibrates your overall heart health score, chronotype, and resiliency. It also picks up when you are sick. I felt horrible one day and it picked up that my body was fighting something. That blew me away. It charges quickly (about an hour for full charge) and I think I can go 3 or 4 days on a charge. The app isn’t free but it tracks so much with accuracy that it’s worth the money. I paid for the year which was $69 but you could do monthly for around $5. This ring really is worth the investment if health tracking is import to you. I highly recommend and so glad I finally broke down and purchased. Don’t waste your money on other brands- they either don’t work or stop working after about few weeks. ... show more

    • Seems Accurate
Review Image by Pierced🦋Papilio
I’ve been wearing my Oura ring every day and night for a little over 3 months and it seems very accurate. I’m usually skeptical of wearable monitoring devices, but often try them nonetheless, so I use several different ones, along with non-wearable, more accurate monitors to compare reliability. The Oura seems to be spot on with my sleep, stress, and activity. It’s always detected my naps and routine “workout” activities (I created a label for my strenuous every day activities). Those are really the only stats I look at. Battery life is pretty good (mine usually needs charging nearly every 3-4 days). It’s very stylish and comfortable. I like the pulse ox and heart monitors as well. It works very well with the Apple Health app and integrates seamlessly. The Oura App is also very well designed and functions perfectly. I have not been very careful with my ring—I‘ve dropped it twice on a hard tile floor and I also wear it while working with power tools and while doing light construction/carpentry/craft work and it has held up exceptionally well. I also have worn it while washing my hands, but take it off during bathing/showering. When I first purchased it, I wore a silicone ring over it for protection, but it was too bulky. Overall, I am very happy with this tracker and would definitely recommend it. I love the sleep tracking with my Apple Watch, but sadly, it needs to be on the charging dock at night, so that feature is pretty useless for me. The Oura, however, is perfect. ... show more

    • Fashionable and provides fascinating health and fitness insights
I was really hesitant to purchase this product, mainly because of the high price point and the subscription based mobile app. While I do understand people's hesitation with the subscription model, I feel like the ring has helped me a lot in the short time I've had it. It seems to be surprisingly accurate in it's sleep tracking, heart rate monitoring and fitness tracking and I often compare it against my apple watch to see if it compiles similar data. When it comes to sleep, the Oura ring has helped me to develop routines that make for a good night's sleep and gives me valuable insight into my quality of sleep as well. I don't like wearing my apple watch to bed, nor while I am lounging around the house so the ring has been great to help me keep track of things like my steps, calories burned etc. and offers reminders to stand up and move around. The biggest drawback to this product for me has been the size, I have the largest size and it is slightly too small for me. I am a larger guy and the size 13 would fit better if it was ever so slightly larger but most of the time it isn't a problem... except for when I sleep. My fingers swell a little bit at night time, which leads to me waking up from discomfort cause by the Oura ring and I find myself switching it back and fourth between my index and ring finger throughout the night. I did wear the sizer for a full 24 hours as recommended but the actual ring feels very different from the 3D printed sizers. I am making it work due to the fantastic data it collects. Overall, I highly recommend this product! ... show more
