WeDo vs Amplenote

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.

Any task with a date/time assigned to it will be exported to calendars optionally connected. Completing the task removes it from calendar.

Any note can be assigned as many deeply nested tags as desired. The tag hierarchy can be navigated, filtered on tasks or notes.

Amplenote supports the same [[]] syntax popular in Roam to create a link to an existing note. Every linked note has a tab with all the references into that note.

Every task can be marked as "Urgent" or "Important," along with the time it's due. This makes it possible for the software to automatically sort your todo list in a way that makes sense, and save you time of deciding what to work on first every day.
