From the developer:
Suru lets you organize and outline your new projects, today’s to do list, your next vacation, your team’s latest brainstorm, and everything in between. You can structure and organize your notes in the way that makes sense to you. Thus, you will never forget an upcoming task. Also, you can illustrate core concepts to your colleagues and collaborate on shared projects with your team.
