With the Fitbit One you could long press the button to activate sleep/activity mode, which would immediately start a visible timer. I have different bedtimes every night, so knowing the duration of my sleep when I wake up is really important (if it’s not enough, I go back to sleep). It’s such a simple thing but none of the trackers support it except the old ONE
Which is fine if it auto-detects, but sleep is just like a fitness activity for me. I want a live readout just like if I were on a run or something. I need to know my progress at a glance to know how much longer I need to go. I can’t wake up in the middle of the night and sync to my app to find out how much more sleep I need.
