2Do vs Checkvist

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.

Checkvist hits a sweet spot between minimal and complexity. It gives you a host of options and extras to use on your lists, but you can completely ignore them if you don't need them and keep it very simple. This makes Checkvist a one-stop shop, regardless of what type of 'list' you need.

Search filters help you search for tasks by tag, due date, assignee, etc.

To-do lists often need to be grouped and regrouped for clarity. The outline-based nature of Checkvist makes it easy to move things across categories, to increase and decrease priority, etc.

Parses markdown, html links, hashtags to become formatted text, clickable links, and tags, respectively.

Checkvist offers many free features if you are using this individually.

Any item can have a free-text comment, which can be shown or hidden as desired.
