Does anyone use Cardiogram here? I wanna try it out, but it says I have to do it though the bedtime function in the Clock app on the iPhone. I sleep when I go to sleep, I don't know when that will be, and I don't know when I'll wake up. Is the only way to get it working by setting up my bedtime with an alarm for all days of the week?
I use cardiogram but I haven't setup any sleep function on it. It still shows my heart rate while sleeping.
I'm also using pillow now as it's free and it seems to work well.
Edit - I did buy autosleep yesterday and when comparing the results to Pillow they aren't even close. Pillow seems to be much more accurate in my view.
