TicWatch Pro 5 and SaA for Sleep Apnea

Sleep as Android Q&A
1

Hi All,

a quick overview of my experiences. See the below discussion for an original overview of my journey. I have moderate supine based sleep apnea. I have been undertaking sleep positional therapy (essentially using a pillow to stop me sleeping on my back, where I snore most) since Apr/May 2024. I’m also currently using NightShift to help track things for a 3 week trial period.

As suggested below, I purchased this watch.

I am concerned though, with the findings of this watch below. Must be noted though that it didn’t test the blood oxygen level as well., which is the main reason for purpose along with the sleep tracking component.

Would love to know why Petr loves this one so much, other than that it allows full open source sensor access. Poor performance though would somewhat negate any value in sensor access IMHO. Thoughts, Petr?

Is it a case that combined with SaA data/tracking it somewhat improves the reliability of the data? I’m not convinced, as it’s my understanding in my chats with Lenka that the app does’nt track a lot of data, as it relies on what it pulls from the watch. Do I have that correct, Lenka?

I can say, have had a lot of help from Lenka over the past few months understanding the data/graphs for all this. Thank you, Lenka.

I must say, I find the SPO2 very unreliable during the day, but seems very consistent in showing readings during the night. Obviously less activity during the night helps with that. I recently had a medical grade device for 3 nights, whilst also using this watch and SaA, and hope to get the report next week, so I can compare what it shows to this setup of watch/SaA. I’ll update this post once I do.

Thanks all.

Mark

Thank you @mgs1968 for your contribution. I look forward to your future updates. SpO2 tracking was one reason, among several others that led me to buy this watch about a month ago. I have somewhat of a snoring issue. Have you also tried the snoring alert sounds? If so, have they helped? Both @lenka-urbandroid and @petr-urbandroid have been helpful over the past number of years. They’ve been the most responsive team I’ve encountered of any app I’ve ever used.

Hello @mgs1968 … I love the Pebble watches as they were perfect combination of features, great display readability on direct sun and battery life. Over the years nothing did come close only the TW3 70% and then TW5 90%.

A very good test of the SPO2 sensor is Wim Hof’s breathing technique :slight_smile: I have tested the sensor and it seems the react as expected. Of course the SPO2 sensor on a wrist heavily depends on the tightness. So when my band is loose my SPO2 drops to 70 many times during the night which is a false positive. But when I tight the band completely at endge of comfortability I get 95-100 readings from my night.

And exactly as you say, to track SPO2 realibility the arm has to be still. You cannot track SPO2 with this type of sensor if you hand is moving!

Of course as an engineer I appreciated that Mobio opened the sensors for 3rd parties and it is a big pitty nearly no nody else is doing this - Pixel Watch, GW etc…

What issues are you having with the Tic Watch?

@raymillr Big thanks :slight_smile: very much appreciated!
