The Sleep Cycle app tracks user’s sleep patterns as they go through different sleep phases and identifies these sleep phases by tracking movements in bed.

Data gathered from app users revealed that the best sleep quality worldwide occurs on a Wednesday night, with fifty eight of the countries surveyed saying they had the most sleep on this day.
