I have been comparing step counts of Oura 4 to Pixel Watch 3 for two months now and there’s ever only a maximum 300 step difference. I was shocked how close the Oura was as steps is really all I wanted and my Oura 3 sucked and was wildly off (slightly too big, too, as I start to suspect…)
I have a Venu 3 and an Oura 3 over a few years in total. Oura is good to identify waking up at night without remembering (short noises outside like trucks outside or trains etc), so you can start working on that when you wake up tired. Once you have worked on those items, no need for an Oura anymore. And alcohol is really bad for sleep. Sleep stages are questionable on both systems, but for me Oura works better. The key items are the duration of sleep and the resting heart rate at night. RHR is the best value for coming infections and those two data points are covered by all systems.
Oura is the best in the industry for sleep tech cuz they’ve been specializing it for the longest Oura is def the smallest and most comfy for wearing to sleep Battery will vary depending on model. I have a 3 and it lasts maybe 3-5 days? For the 4 I think it’s up to a week
It can track some activity but it’s not the primary strength of the Oura - sleep tracking is its bread and butter. The same way that I wouldn’t call an Apple Watch a sleep tracker, just because it can do it doesn’t mean that that’s how I would label the item. Something that really annoys me about Oura’s tracking is if it doesn’t register that I did an activity, I can’t add it manually once it’s past midnight
The review says it's great at sleep tracking and general vitals. This isn't for people who want to track their sports performance. It works great for general health tracking as advertised.
I don’t care about Oura, and I already agreed that it’s not the best. I just hate being mislead. I can’t even find that statement on their website, and nothing in their advertising indicates that Oura is targeting the athletes. Regardless, taking one statement to say it’s advertised directly to athletes is ridiculous. “Trusted by” means absolutely nothing in advertisement.
This is the best feature so far. Sure the sleep tracking has been available on many devices, but it's too cumbersome to sleep with.
1. Sounded like a cool technology that i wanted to try out. HSA also covered it. I just passed my 2 year anniversary with Oura 3, still tracks well but the battery is starting to suffer, i’ll have to get it replaced soon. 2. My sleep and resilience score 3. Sometimes, if it tells me to take it easy/rest, then I will 4. Habit 5. Health reassurance 6. I don’t get as much sleep as i thought i did (it’s very rare i get a score in the 90’s). My HRV is also very low, but I learned the difference is unique to everyone. Low is okay if that’s the normal for that person 7. Would it be cool if it measured blood pressure, but i know that is probably impossible from just the finger. Telling us exact temperature would be nice, but that is pay walled unfortunately (requires you to pay for a separate app- the one I’m familiar with is the ovulation tracking app called Natural Cycles that integrates with the Oura app data, i’ve tried it before but didn’t feel it was worth paying an extra subscription fee for it) 8. The biggest and most important reason I use it and without this feature I probably wouldn’t miss out on using —- period tracking. i can now accurately predict the day before i get my period. I learned that my body temperature will drop 0.1-0.2 degrees from baseline the day before, and the day i actually get it my temperature will drop down to 0.6 from baseline. it’s sooooo worth wearing just for that tracking alone.
Gen 3, 2,5 years of usage, battery worked for 1.5 days. Practically I was charding every day. Gold. Got washed away quickly, was noticeable after 3 months. Gen4, grey, about a year of usage, battery works 2-4 days. Black, one of the cheap ones, scratches and wearing out is obvious.
