I create a lot of tasks throughout the day and have used Google Tasks and Any.Do for this.
The reason I love Google Tasks is the universal availability and simple interface and also the integration with Google Calendar and Gmail…
I don’t like Google Keep much though.
With Any.Do, its just that I don’t use the app and in chrome etc. with the extension, the usability is limited…
Note that for me tasks are not Notes or Clippings. For these I use Evernote at home and Office OneNote 2013 at Office.
These have worked out great for me except a small hiccup with Evernote in the beginning when I was constantly clipping the whole page and ran out of storage capacity in the 1st month…now I clip parts of the page and its been good since….
