Guys, I am working on Go2Sleep blood oxygen ring integration.
Right now HR & SpO2 works fine, vibration feature is going to be released by the end of the week and I’m communicating with @petr-urbandroid to support Go2Sleep addon in next SleepAsAndroid beta release.
Ping me if you want to be a tester.

Hi Den, i have see Go2Sleep in Facebook yesterday! I want to be a tester.

What’s process to be a tester for your ring?
Has anyone compared the two products o2ring and go2sleep? I’m trialing the o2ring and I’m impressed by the data granularity. Does go2sleep record every 4s like the o2ring? Integrating it into SAA would be amazing but maybe go2sleep is a better product?
I do not know what is the frequency of o2ring measurements.
But Go2Sleep record data every 1 second.
That’s very interesting. O2ring measures every 1sec and records every 4sec. Go2Sleep sounds like it may be more granular. I’m trying to find reviews on go2sleep but have only found negative comments about poor connectivity. How do you find it?
I had same issues with poor connectivity when I just received the Go2Sleep ring.
But after firmware upgrading everything is fine.

How do you find the tracking of your SPO2 and HR data? I have tried fingertip based units (with a wrist based watch type unit) and they sometimes lose tracking when you move too much during the night. The fingertip versions place a light on one side of the finger and a sensor on the other side. This go2sleep seems to have both light and sensor on the same side, much like most watch HR sensors? I wonder if there’s a difference in performance during movements between the two types? Do you find it is relatively consistent throughout the night? I’m considering placing an order but worried about this performance issue. The o2ring that I’m using seems to be very consistent as the sensor never moves even if your fingers move at night.
Go2Sleep has special movement detection for what you described. If you move too much ring can detect it as you put off the ring from the finger. The trigger level of this “put off detection” can be controlled by user and called “sensitivity”. In the other hand you can even disable it by setting “sensitivity” to 0.
I have not tried o2ring, can’t say smth about it.
But I can compare Garmin Fenix 6 and Go2Sleep to tracking sleep.
Go2Sleep much better, because Garmin measure SpO2 whenever it wants (can do and don’t) and you can not control it as a user.
Does go2sleep record to its own storage when connected to your sleep as android add-on? So can you analyse the go2sleep data (via its own app) independently to SAA’s results?
Hi all,
I used Sleep as Android for two years and did a break of 2 years. Now I am back, and I am highly interested in the pulse oximeter measurement. As I can take out from the discussion here, there are probably two devices that are accurate and work well with Sleep as Android.
- Go2Sleep (small white guy around 100$)
- o2Ring (little guy around 300$)
So for me, there is a massive difference in the pricing. So my question is:
- If I would decide to buy an oximeter, should I stick to the two mentions above, or could I use any other? On the official sleep as android site, it is written that there is only support for the »StressLocator pulse oximeters«
- Can I use any other oximeter which might be in a range of 40$ to 80$?
At the end of the day, I am not sure if this will gain anything to my sleep? I am using a Polar H7 in combination with my smartphone and »sonar«. I am wondering if these oximeters are well in heart-rate measurement as well. I believe so 
So any advice from your side?
Thanks Tobi
PS: I am located in Germany.

O2ring seems to be a very good device and seems to accurately tracks spo2 overnight, but it does not work with SAA (at the moment at least). Can’t comment on go2sleep but it does look promising.
Stresslocator is an ok product but it doesn’t record to its own storage (which is something I want). It doesn’t always track very well as it relies on a band that wraps around your finger using velcro, which is then attached to a watch device via mini usb. Lots of places that can detach during your sleep (and often do) unless you tape them up (usb conector and the finger band).
The cheaper spo2 measuring devices are only intended for soot checking oxygen levels. They aren’t designed for extended use and won’t really work overnight. They are definitely useful but just be aware of their intended use and what they cannot do.
An accurate hrm does appear to provide better sleep stage insights than without and the spo2 measurements help identify oxygen drops, which may correlate to sleep disturbances.
I use a sleep phaser light from happy electronics, which is similar to sonar in functionality but relies on IR, not sound.
Now just trying to decide if I should buy the go2sleep device.

Yes, they work independently and do not break each other.
You can track your sleep with Go2Sleep and next morning you will get SAA sleep report and Go2Sleep app report at the same time.

Nice work! The heart rate and SpO2 sensors work perfectly.
May I ask will movement tracking be supported soon?

Hey I stumbled upon this bored after downloading sleep as a trial. I’m undecided on full version from what I’m reading I cant use my wellue ring.
Samsung health randomly dropped polar h10 as an accessory which got me looking for other fitness apps… which got me to google fit where if I’m gonna go through the trouble of using that I may as well maximize features. What is the latest word on more pulse ox readers working? And if not how good is sonar? I sleep with my girlfriend, 3 dogs and loud air conditioner unit is it accurate enough to just buy the app and make it work? P.s I dont cate for things on my wrist otherwise I would have bought a Samsung gear awhile ago
I hope so.
We are negotiating with Go2Sleep vendor team about it.

Hi everyone,
Today the Go2Sleep device arrived at my place. So far so good. I can connect it with SAA but no heart rate is detected so far. As I want to have a more accurate sleep tracking while using heart rate, I don’t want miss this feature. Up to know, I used a polar h7 sensor which is sometimes not too nice to wear during the night.
However, the Go2Sleep ring is much more comfortable and I guess the oximeter will work (will try it today in the night) but I want to have the heart rate too. Is it possible? Can I programm the api myself?
Using two devices is not possible or? If the Go2Sleep heart rate will not work, I am not sure if I will stick to the product.
So first feedback. The night is over. Either heart rate nor oxygen was measured during the night in sleep as android using Go2Sleep…
However, just saw that there is an app already . However, the usage of the app is not well described yet. Just start it and then run SAA in addition? Do we have to select a heart rate sensor and add oxygen measurement too?
