Anyone have recommendations?
Apple Watch.
OP works at Google. Apple Watch is iOS only. So perhaps not very likely to be a good fit.
fitbit alta hr. Battery lasts 7 days. And tracks rem and deep sleep too
Aw4
Ive had the fitbit charge 2 HR and apple watch 3. Fitbit is way better for what you described.
Definitely not Samsung
my cpap does a good job of monitoring my sleep quality. usually the number of events throughout the night correlate with how I feel the night afterđ
Amazfit Bip. 4-week battery life.
Fitbit versa. Great battery life.. And really good for the aforesaid trackings
I have Fitbit versa. It doesn't do variability.
