Sandglaz vs Todo by Appigo

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.”

Todo syncs quickly across all your devices.

The app is easy to use and supports many work styles.
