苹果手表的数据不能用，必须用这个app的硬件

想添加亲友，缺死活找不到ID号码，一点儿也不智能，这是app的bug吗？

就一个睡眠监测器的配套软件，非要手机号注册，就这么想知道用户的健康隐私。

11/4. Keeps telling me I need to update firmware, but when I click "update" it says I have the most current firmware and the feature I was trying to access doesn't work. After trying this device for a time I'll update my review.

I wear the SLEEPON ring for a few weeks now. It stopped recording twice 2 Nights in a row. No tech support number available. Email took a few days to respond. Copy & paste answers; none of them help. If you want a 5 star review, please earn it!

I know what my basic heart rate and O2 saturation are. The readings are completely inaccurate and I’m so disappointed. I wanted this to really work. I got the fingertips sensor and it’s completely an inaccurate. :(

Sleep apnea is probably as prevalent and detrimental as hypertension. It is also as insidious and requires technology to monitor and analyze. This ring packs a sophisticated sleep lab into a tiny package. Remarkable. In my opinion, they should be routinely distributed to people at medical wellness visits. (I am a physician)
