Smart Wake Time (Optimal time based on sleep stage)?

[Mike2401]

Are there any fitness trackers (fitbit or other) that tweak the alarm time based on your sleep stage?

I normally get 4.5 or 5 hours of sleep.  I got 5 hours but woke at 3am for an early flight and felt terrible all day.  I wonder if sleep stage could have had anything to do with that.

Thx for any solution suggestions,

Mike

Hi @Mike2401 ,

I don't know of any fitness trackers that do that, and I'm not sure it's easy or difficult to implement. Most trackers I've seen, including Fitbit, calculate the sleep stages at the end of the sleep period. It seems they're not tracking stages real-time.

I discovered this by editing the start/stop sleep times, and noticing that it affected the graphs for sleep stages.

I used an Android app that did this very well, but got tired of having the phone in bed.

Edit: It must be possible, as Fitbit is considering this feature. Add your vote at the link below so Fitbit knows we want this.
