Sandglaz vs GTDNext

The interface is built around the concept of "infinity grids" where tasks are placed into time-based milestone periods. Any non-completed tasks from the current milestone automatically move to the next milestone. As such Sandglaz is best suited for teams that plan projects and tasks in milestone sprints.

The interface consists of columns of tasks organized in either days or weeks with a slide-out panel for accessing settings, search, notifications and navigating projects. Expanding a task gives access to adding subtasks, notes, attachments, comments, setting due dates, etc. Overall the interface is very utilitarian in execution with only the bare minimum of functionality taking up the space at any given time.

Tasks are assigned with @username. Each project can be shared with its own team of collaborators. And hashtags are used for categories.

Uncompleted tasks move to the next day automatically.

You can assign tasks with @username and communicate about your collaborative to-dos right within the context of the tasks. You can also share each project with its own team of collaborators.

Sandglaz allows users to create really smart recurring tasks – everything from “weekly” to “on the fourth Saturday of the month.”

All the “Get Things Done” lists you would expect: next actions, someday, waiting, and scheduled.

When it comes to choosing your next action, most to-do apps suffer from the same problem: All of your actions (sometimes hundreds in total) are visible to choose from. This can overwhelm users and cause them to give up on the system. GTDNext is different. In the "Next Action" view, only the very next action is shown for each of your projects. This results in a nicely consolidated view of only the things that need your immediate attention.

In GTDNext you can set up an unlimited number of levels for your projects and actions, allowing you to plan your project and sub-projects in as much detail as needed.

GTDNext supports the “Areas of Focus” methodology from Getting Things Done. You can filter all of your tasks to just show your work tasks, side project tasks, or personal tasks. There is also a global filter, so that when you’re hard at work you can focus only on your work projects and tasks.

This is really useful because it prevents you from having to navigate through each project individually.

The number of keyboard shortcuts makes it easy to log or add tasks without removing your hands from the keys.
