The New Tools tab includes two really beneficial features: the Weekly Report and the Nightly Sleep Report.

These reports are a great way to see your data at a glance. The Nightly Sleep Report shows your ZQ breakdown, your Sleep Graph, and your journal entry for one night.

The great thing about the Cause and Effect chart is that it works with your Sleep Journal. This means that when you customize the chart, there are a number of different options to choose from so you can really zero in on what is affecting your sleep.

For example, if you wanted to see how your Time in Deep was affected by your Level of Activity, just select Time in Deep from the left-hand drop down and Level of Activity from the right.

The Trends chart allows you to see trends in your sleep habits, which is terrific because you can start to figure out what your habits are and how they affect your sleep.

The Sleep History shows your various nights, weeks, or even months of sleep at a glance, allowing you to see how it can fluctuate over time. You can filter this data to show ZQ, Total Z, Time in Deep, Time in REM, Time in Wake, and Times Woken, making it quick and easy to spot trends in your sleep behavior.
