The range of SAA statistic is huge, but honestly, the readability is sometimes not so good.
I bought TicWatch 5 Enduro to get better results with SAA. What surprised me a lot is their app. They have some pretty helpful and clear graphs which shows information you really wanna know most and which SAA doesn’t show you at all or all over the place in bad form.
There is a lot of inspiration to take from their app and since you like the watch as well I encourage you to explore their app as well.
But here are two main thing I like to see in SAA which are super important.
Hypnogram
Hypnogram is … I’m sorry, but it’s a terrible graph. The way it shows the different phases is ultra intuitive. Using the horizontal line as time is perfect, but why for example REM is filled through deep sleep and light sleep as well? Why does the higher phases occupy the places of lower phases? It’s very hard to read. (I guess it because the hypnogram is technically just Aktigraf segregated to phases - but it doesn’t mean it should stay in its current form)
This is how the Mobvoi Healt does it and I think it’s superior:
It is very clear what are the values in minutes and %
It shows you what your values should aim for and how different +/- they are - numerically and visually
The absolutely mandatory info, which I’m surprised aren’t In SAA in one graph. Some of them can be found in very specific places, but the rest can’t be found at all.
What do you think? Is there still some space for improvements? Do you see my point of view?
Hello @OndrejVasicek … many thanks those are definitely good points, we already had few attempts to redesign the hypnogram but we also have a lot of conservative users so every change is hard… anyway we are looking into this…
In general we do not want to emphesis the ~REM info too much as REM without an EEG is always just an estimate…see:
and
So the idea in the hypnogram we want to clearly separate deep sleep from the other forms of light sleep.
We use both the deep sleep % and Awake % as the main part of the Sleep score, but do not rely much on REM% which IMHO does not tell much info…
Last but not least our depiction of the hypnogram is very similar to the depiction used in sleep labs…
But we definitely like to improve the hypnogram clarity so big thanks for your commont on this…
@OndrejVasicek Very interesting… I have the TW Pro 5 Enduro too. I love it, and like its sleep stats also. I’m not against your idea, just used to SaA as I’ve used it for years. If I remember correctly, in SaA, if I delete an erroneous awake time, it shows the underlying sleep level. For example, awake time may start during REM cycle. On deleting the awake time, it seems a longer REM time may then show, as if the awake time was an overlay. Of course, I just got the watch maybe a month ago, so I’m still getting used to it. BTW, this is a little off-topic, but have you been able to get HRV to show in SaA using your watch? It should work, but mine didn’t. Then it showed for two nights, then stopped showing. I posted elsewhere in the forum (and communicated with @lenka-urbandroid, and maybe @petr-urbandroid) but haven’t figured out a solution. Any thoughts?
Yesterday I received the Wear OS 4 update and also my HRV got lost. But this should be fixing the issue, although I tested only with a short track not over night yet…
Strange, are you saying your HRV worked in 3.5, but stopped with OS 4? Intriguing, as my HRV didn’t work, then worked then didn’t work in OS 3.5, all BEFORE I got OS 4. I’ve never tried one of your apks yet. It’s that a beta? Forgive my ignorance, but do I just click the link and then follow some instructions? I’m excited to try it out… We’ll I just tried it, and got a message it wouldn’t install as it appeared to be an invalid app…? I have the latest update and latest Pro Unlock update latest watch update. Now what?
Hi @raymillr, the addon for the Wear OS 4 is still under testing, because there are some troublesome permission.
The version for the addon is https://sleep.urbandroid.org/wp-content/uploads/release/SleepWear-5.20.apk on our website. It needs to be sideloaded on the wearable (not on the phone).
Sideloading apps on the Wear OS is a bit cumbersome, sadly. You can check the guide here or here.
@raymillr Yes, my HRV tracking on Tic Watch 5 Pro worked realiably every night on Wear 3.5, but stopped working after update to Wear OS 4… I hoped I have fixed it, but it seems not really…
It seems they messed up something in Wear OS 4 update…
it is really strange becuase when I connect the watch in debug mode I get all the RR intervals no problem, but when you disconnect the watch under normal condition the sensor simply stops sending data…
@raymillr it seems the new Wear 4 body sensors: all time permissin was not granted properly… so now I hope the issue was caused by the permission but I need to do more tests…
@petr-urbandroid I tried to sideload the .520 apk following the bugjaeger steps in the first link you sent me. I read the instructions in the article multiple times since I never tried an apk sideload before. The pics in the article didn’t quite match the bugjaeger app I just downloaded, but got to the apk installation process. I don’t know if I should have seen some sort of completion notice, but I saw afterward, bugjaeger showed no device connected. On my Ticwatch Pro 5 Enduro, I turned off wireless debug, and ADB debug. I then restarted my watch, went to the app info on the watch for SaA, which showed Version 5.16. Does that mean the apk did not sideload? Sorry to bother you as I’m new to this, but perhaps you can give me next steps?
Looking forward to your test results.
