In week view, tap on date header and day appears for that date.
Tap that day/date header on the day view and go back to week view.
This allows closer look at each day from the week view.
Also.....,
If the this app icon could display the current date I would then replace the iPhone date app with this.
Also bold text in day view.
Place location line below instead of beside in day view.
Great app.
