To Round vs WeDo

The interface is clear and smooth.

The bubble design format is simple to understand visually and is effective in keeping track of ones to-do list.

To Round turns task-completion into a game-like experience, which is good for those who are motivated by this type of positive feedback. It can be a little distracting or annoying for users who want an even simpler process.

The app features an Android widget that you can place on your homescreen to view your current tasks even more quickly.

You can enable push notifications that make sure you never forget a single task.

The app uses bubbles to represent tasks. The bigger the bubble, the more important the task is.

Has versions for Android, Web, and iOS.

You can attach files to each task.

It is a new app, but they have a very good interface so the users can send their suggestions to improve the app.

It allows users to set recurrent tasks.

You can add subtasks to any task.

It allows you to assign tasks to other person. If he/she does not use WeDo, it sends an invitation.

At least for a while.

You can add groups, and for each group, yuou can add members. It is something like Trello Boards, but I think its better.
