There are some products out there that attempt to measure sleep quality via leaving your phone on the bed, or wearing a bracelet. I'm not sure of the accuracy, though.

I hope these will get even better (maybe a non-intrusive headpiece that can measure brainwaves?) in the future.

I have the Sleep Bot app and it measures movement and sleeping time and graphs the data. It doesn't give any analysis, however.

Do you have advice for a better analysis of my sleep each night?
