In Pictures: Android lock screen widgets, 20 excellent options

Any.do

Any.do is another excellent list-making option. The app features a gesture-centric interface that organizes your to-do tasks by day.

Any.do's lock screen widget follows that same day-by-day approach. It lets you scroll through your list and mark any item as complete by tapping it. It also has commands for adding new to-do items by either typing or speaking; when you tap either of those commands, the system will prompt you to enter your PIN/password/pattern code before you can add a new item.

Any.do is available as a free download in the Google Play Store.
