## Description

SleepO2 Wrist Recording Pulse Oximeter by EMAY | Continuous Pulse Oximeter to Record Blood Oxygen Saturation and Pulse Rate Overnight | Export Sleep Report & Raw Data : desertcart.co.uk: Health & Personal Care

Review: Reliable oxymetry recorder - I need the device for overnight recording and, having owned other recording oxymeters, I find that this one works reliably, with a stable signal, and the sensor is reasonably comfortable and does not easily come off. The battery reliably lasts overnight. There are no signal drop-outs, and the measurements appear accurate. The phone app can export data, and the output format is compatible with OSCAR. It is important to note that this is a designed for overnight recording. Even though nominally it can be used for spot measurements, this is not its primary purpose, and therefore spot measurements require some fiddling with apps and settings. In all, a single-purpose device, that does what it is designed for, and does it well at a cost sensible for a home user. It does not replace a spot oxymeter however, so, for spot measurements, I use another device. My only (very minor) gripe is that there is no alarm if the saturation drops. Again, this is not the intended use, but it would be a very easy function to add to the app, so I would be very happy to see it in the future. For the moment, I keep using it for overnight recording.
Review: Excellent product. - Excellent price point. The device does what it says it does and is easy to use. It generates detailed reports which display heart rate and blood oxygenation over time. I recommend it.

A: No, the app is free.

**Q: Does this record the motion?  the wellue app shows spo, pulse and the motion on the app screen  when you down the reading onto your phone**

There is nothing in the manual or App settings for motion detection/monitoring that I can see.

### ⭐⭐⭐⭐ good experience
*by L***E on 24 August 2025*

delivery was fast. product as description. its packed in a cubic plastic box. handy to use&store. battery charge is fast. roughly can use for 2nights for 1 charge. connection with phone is good by Bluetooth. data can store in the watch & disconnect the phone while using. save phone battery & no blue light during sleeping. report can be shown to doctor as reference. the finger cap is spacious. good for thick fingers. but mine is narrow. i find its loose& would fall off. i needa fix a bit by something add on. its also written in users instructions. the battery indicator shows only when its in live mode & connect to phone. the band doesn't contain screen. overall, its effective gadget if u wanna have reference of ur oxygen levels & heart rate.
