2Do vs aCalendar

2Do conforms to your workflow instead of forcing you to conforming into some preset workflow. It helps to accommodate your workflow through a series of features including tags, batch editing, configurable presets, and the ability to quickly add tasks at any time.

Adding a task can be as simple or complicated as you like. A to-do list entry can simply consist of its title, or you can also add notes, recurrence, set a due date, tag a location, schedule an alarm, priority (low, medium, high, starred) and tack on a URL or photo. You can even make an audio recording with voice notes. And each list is sortable by a number of criteria, including priority and due date.

Unlike many other apps that will release a new paid version when major features get launched, 2Do doesn't resort to that.

Use a combination of tasks, projects and checklists.

You can use 2Do according to the Get Things Done methodology – or not.

Find old tasks or organize smart lists based on complex search terms (for example, “tasks to do at home between 6 pm and 11 pm”).

The app can optionally sync with iCal or Outlook with free helper software available from the 2Do Website.

Tasks get shown in the calendar, although there is also a separate tasks view. It supports Google Tasks and recurring tasks.

Switching from day<->week<->month views by swiping laterally is a powerful feature.

The settings menu is rather detailed and includes a good selection of color themes to choose from, possibility to adjust font-size, set beginning and end of day, ability to choose what views to use and more.

aCalendar is an Android app that comes in free, ad-less version as well as this paid version.

This paid version aCalendar+ adds more features like agenda view, home screen widget and the ability to manage Google Calendars. The developer also donates some of the profits from this Pro version to help protect the endangered mountain tapir.
