Is there a way to see yesterdays step count? I’m usually up past midnight and I hate to look down and see zero and not know how many steps I walked!

As far as I can tell the tracker automatically changes to zero once past midnight. It doesn't keep records.

How does sleep monitor work? Does it count time as soon as it’s turned on? Or sensor if you are in sleep or not?

Dear customer, this watch can only record the total time you have slept. And you need to turn on/off "Sleep" function manually. This is the setting steps: Short press the circle button to the "sleep" interface, then please hold on the circle button for 3 seconds. (You can short press the circle button to turn on/off the sleep mode) You can select "ON" to enable the sleep mode, then hold it again to exit the sleep mode. At the same time, there will be a moon icon on the page of this time display. When you wake up, you can select "OFF" to disable the sleep mode, then you can get the sleep time. Hope this helps you.

Can you set it so that the screen doesn't keep turning on all the time? I'd rather just push the button when I want to see it.

if it’s been sitting quietly (off) and you kind of jerk your arm, it may turn on very briefly - the person I gifted it to didn’t say it could be set to remain off but she did indicate as a rule she pushes the button when she wants to see something
