2Do vs Nirvanahq

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.

You can set how long a task will take and how much effort will it ask of you on a scale of 1 to 3.

A vital functionality in a GTD app.

Clean, intuitive user interaction. The design is very thoughtful. Somehow it makes Things feel clunky, despite obvious similarities of all GTD platforms.

The app can send you the most important items for the day in an email.

You can postpone a task. It helps not to clutter task lists up until you really need them.

Clean, intuitive interface — both desktop and mobile. Lots of intelligent design thinking behind this. Somehow makes other GTD apps like Things feel clunky, despite similarities.
