Pretty good

I use this to determine whether taking melatonin is having an impact or whether I need to go back to my sleep meds. I agree with other users as my cats and dog get in and off the bed. Also, I stay relatively still prior to falling asleep, so the accuracy of this app is in question. But Im hoping that over time I will be able to get some sort of reliable measure before I see my doctor again.
