Hey guys, I was wondering, how this band is actually measuring the sleeping patterns?
Does anyone have any idea?
And why it doesn't detect my movements in the public transport?
from the about page looks like is using activity recognition library offered from google
Move a lot in bed -> light sleep, move less in bed -> deep sleep. That's it in short.

Hello all,
There appears to be a few accelerometer based sleep apps that track your sleep cycles available. I always have issues waking up so the ability that these programs have to wake you up when you are in the "lightest phase" of sleep has been truly godsend. I have not been late to work once since I began using it (usually at least 3 days a week I'm late. It is truly life changing so far for me. But id like some feedback if there are other apps out there. or what personal experiences are. Id also like to know what most of you have for your "deep sleep ratio" to see how I stack up.
Sleep as Android - I am about 5 days from the trial version expiration of "Sleep as Android". So far I love the program and am highly considering purchasing it when the trial is up. I love that it can determine the best time to wake me up, and I have a nice graph of my movements through the night, another feature I like is that it record my noise. I have found that In the beginning I was a loud snorer it has apparently gone down by utilizing an eye mask that puts pressure on my nose as well. Just about everyday my % of deep sleep is falling into the 45-49% range with one bad night being 23%.
Sleep timer - I will be trying this program this weekend once my trial version of sleep as android is up. I want to test it over the weekend so I dont miss work or anything. will update my experience
Anyone have experience with other programs or the ones I mentioned?
Electric Sleep - Not tried yet
Smart Alarm Clock -Not tried yet
Gentle Alarm -Not tried yet
Suffering fron DSPS and Non24-h sleep/wake syndrome so it's crucial for me to monitor my sleep. Up to a year ago I was using SleepSense for WP6 when I reverted to Sleep as Android and was amazed by the features.
However recently I discovered Sleep Time which works in a similar way but is way more simple. Just enter the time, the offset, a couple of settings and you're good to go. Plus, the shake-to-snooze feature is awesome. I couldn't decide which one to use so I'm using them both on my two devices lol.
Sleep as android Trial ran out. I have been using sleep time I will post my thoughts on it below.
I like the charts given by sleep time a little more and it attempts to break your sleep into 3 segments (wake, light sleep, deep sleep). regarding the statistics, I am in the same range of sleep efficiency that I was with android so whether it is accurate or not remains to be seen but it is at least consistent. Another thing I can not vouch for on Sleep as android but the "algorithm" claim suggested by sleep time I believe is BS.
Theory, the app measures your movement throughout the night you set an alarm that is the "absolute latest" you can wake up. Then you tell the app either 10/20/30 minutes before the alarm you are willing for it to begin going off. Ideally the app monitors your sleep and as you come out of your deep sleep or in a light sleep phase the alarm is supposed to begin going off. This app is steadfast on ticking to the rules, you say 10 minutes with an alarm of 7 its gonna wake you at 650 everyday whether your in deep sleep or not. I notice my wakes are not as "refreshed" as SAAD was.
Bottom line, I like seeing the graph on this and it is very light on the options, but you cant expect much for free. Personally though, until they fix their setup and stop claiming it is an algorithm waking you up, I could just as easily just set my alarm to wake me up 10 minutes sooner.
Will begin trying another app over the weekend.
I haven't heard of these type programs, but now I'm intrigued (thanks for bringing them up in the forum).
As I understand, we have to allocate a window of time when the alarm might go off. So if I need to get up 5:00 absolute latest, the window might be 4:30 to 5:00.
a few questions:
1 - is 30 minutes a big enough window to make any difference?
2 - is this any better than just setting tradiaional alarm for 4:30 and hitting snooze until you're ready to get out of bed (or until it's 5:00, whichever comes first).
3 -you have to keep the phone in bed with you? How do you avoid rolling over on it?

Short answer, yes. Provided that the app actually works as intended and does not just hit the alarm at the earliest time possible!
Long answer, this has to do with the duration of the sleep cycles, which last about 60 to 90 minutes on average, depending on the person. Those cycles consist of five sleep stages, stage 1, stage 2 (light sleep), stage 3 and 4 (deep sleep) and stage 5 (or REM). In general your sleep goes like this: [stage 1, 2, 3, 4, 3, 2, REM] - [2, 3, 4, 3, 2, REM] - [2, 3, 4, 3, 2, REM] etc.
The important thing is that during stage 2 and REM its easier to wake up, and both those stages last more than the rest, taking up to 65-75% of the whole sleep cycle. So, 30 minutes should be an ideal offset. No matter what time you set the alarm, it's almost certain that 30 minutes before that you will eventually enter light sleep or REM sleep.
That's how these kind of apps work, they're supposed to detect the sleep stage you're on using the accelerometer (based on any movements) and wake you up only during "light" sleep.

Theoretically, it is. If you just set the alarm earlier and it rings while you're in deep sleep, it could be a lot harder to wake up plus you will probably still feel tired and drowsy, possibly for the rest of the day. If, however, the alarm rings while you're in light sleep or REM sleep, it will be easier for you to wake up and you will definitely feel more refreshed.
I've woken up during deep sleep after 8:30 hours and felt awful for the rest of the day. I've woken up during light sleep after just three hours of sleep and had enough energy to pull an all-nigher the next night. It all comes down to general sleep hygiene of course but the actual sleep stage on which you wake up can and will have an effect on the quality of your sleep.

I usually keep it right next to my pillow (flight mode on), in it's case and connected to the charger.
Hi, I have an interesting issue with sleep tracking. S3 starts sleep tracking automatically. However after I wake up I usually sit down on the couch to have my cup of coffee and read news for an hour or so. I have noticed that my S3 detects this time as sleep and reports about it Is anybody having same experience? I know, this is not a big issue however...

I had sort of the opposite experience. It apparently started automatically, but stopped when I got up at 5am for a, um, waste elimination event. I was back in bed within a minute or two, but didn't go right back to sleep. While I was laying there my watch displayed a notification with the number of hours slept (signaling the end of the sleep period, I guess).
This was my first night with the watch, though. Wondering if it needs to learn my patterns?
EDIT: So ... I have to modify my observations a bit. The number I got for sleep time was from the notification that appeared on the watch. When I went into the S Health app on my phone, though, it showed the correct duration, including periods of light vs. motionless sleeping. I've attached screen shots with each of the sleep periods highlighted.
Hi,
since yesterday i have a HW2. Usaly im a wearable user like miband, garmin, Fitbit...and brand new in the android wear universe.
- there are no "nightmode" ?? Do not disturb and shut down your Display between 10pm and 6am setup?
- there a no sleep tracking per default? I try sleep as android. But that lights the display all the night with "Sleeptracking" - and in the morning there are not data
- no altimeter, no barometer per default? (see it on the S3 frontier per default)
A lot of questions and not enough answers

On the clock screen pull down a little shortcut menu that contains airplane mode, sound, theater mode (turns the display black until you press the power button), do not disturb, settings.
There are no sleep tracking. There is though a app called "sleep as android" you can download as you mentioned.
Barometer and altimeter can be showed in some watch faces
Thanks. Today was the second night that sleep as android crashes after 4 minutes on my OP3
Yesterday i had to charge the HW2 2 times - that a but to much. Have to optimize that thing.
Today i try it at my desk. Sleep as android crash after 3-6 minutes on my handy. Dont no why. This log-logger from the faq dosent make a file. Very anoining.
Heart Rate sensor while a bike round. Im not sporty. If my wrist is wet....i get ~70Bpm. If i try that it shows me like i feel. 140Bpm and more. Go ahead and my wrist is wet again....plays start from the begining.
The first 10 Minuites are NOTHING...till the time i dry my wrist.
Today after 11 hours I had only 15% left of the watch. But it was down to 40% before I did a 20 min run with endomondo on the watch and listening to music with bluetooth headphones while running. I also hade a sim card in the watch and the display set to always on. So it was heavy usage. But I did not run for long time..
Air pressure/Barometersensor look not calibratet or whatever. Here we are at 1022hpa, whatch show 1009. Yesterday 1020hps - watch show 1009hpa
Every now and then, I will be fast asleep when all of a sudden, my watch starts vibrating. I wake up and check the notification, which effectively states, "Hey, man! Were you asleep?"
So I dismiss the notification and go back to sleep. Just as I am finally nodding off again, my watch starts vibrating again. This time it reads, "Tap here to find out why sleep is important."
At this point I'm thinking, "My watch can sleep in the microwave... Do this to me again and I'll turn it on!"
...My watch stays silent for the rest of the night.
Anyway, is there any way to disable the god awful sleep detection? It has never worked properly anyway. My watches life depends on a solution.
I have a different issue with sleep detection. When I fall asleep during travel, either in car or train, my Galaxy Watch 4 doesn’t recognise my sleep. Is it the same of all or should I adjust some setting?
I recently switched to Pixel, I want an app that just tracks sleep without me having to press a button in an app when I go to sleep. Samsung Health app would detect when I stopped using my phone and then tell me when I fell asleep and when I woke up 10.0.0.0.1 192.168.1.254 . Google fit doesn't have that, and I tried like 4 different sleep tracking apps and they all seem to require you pressing a button or something when you go to bed.
If such a 3rd-party app would exist, what I doubt, then it requires / uses your phone's sensors to detect movement and determine when you are asleep.
