Create widgets for Android and (assuming possible in iphone) that shows a page on your home screen. The page should be user selectable and default to be “Contents” page. Should be able to see the contents of the screen at a glance and when clicking on the widget opens the page for quick capture.
SimpleNote has a very good implementation of this as shown below:
Something like the Todoist widget would be amazing. Instead of showing the daily Todos, just show Todays note, with a + button to quickly add a bullet/TODO. See: Add a Todoist widget to your Android home screen
