This is a serious problem.

Agreed, it would be very helpful for larger tasks / projects as @Wesley Baker says.

PLEASE! This would be so helpful. Allow subtasks to have due-dates. Very intriguing that you guys do not have this option.

I find it helpful during my "moment" to think about the the next action for my larger projects/tasks. I'd like to be able to enter these as sub tasks to keep them organised, but still have them work just like main tasks - particularly reminders

This is absolutely needed to properly manage your time.

The main task needs to have a "Due Date" and optional "Reminders." The sub-tasks should have the same. My sub-tasks are going to have different due dates and reminders than the main task.

Also a place newest subtasks at the top. Currently, they just get added to the bottom, even below completed tasks

Subtasks should have same drop down list of concrete actions as actions (Call, Buy, Pay, etc).

Would love to see subtasks under the tasks. Especially in calendar widget view.

Could you add Paste a list (line-separated) which then create several subtasks. Idea is explained more here:

https://anydo.uservoice.com/forums/143587-general/suggestions/36809890-paste-a-list-of-line-separated-items-to-create-sub

Just as the Main Task reminder feature. It would be great to see a Reminder for all the subtasks of the tasks.

I am using any.do for Android 7.0. I can't even view subtasks on my phone. I set them up in any.do for web on Chrome, and it's frustrating to not be able to see them when I'm working or shopping (away from PC).

Please!!! put * Reminders in the Subtasks

I view each Task as a category and attach notes and attachments based on the overall idea of the category. I view Sub-tasks as a class, and I would like to be able to save notes and attachments reguarding individual Sub-tasks.
Simple Example:
Task: Colors (notes and attachements available)
Sub-tasks: Red Green Blue Purple (would like notes and attachments for Red Green Blue Purple individually)

This app is AMAZING. Thanks guys!

Completed subtasks should be moved down the list, not up. Now is not very convenient

Sub task should have tags

A task is set for one week. But multiple sub tasks need to be achieved which can have different dates for completion or reminders

Ability to add independent (reminders for sub-task/pre requisite tasks before the task )and relative/follow up tasks (reminders after specific time from main task) will add a lot more value for all dealing in project management tasks.

Sometimes we have a task which we want to turn into a subtask (because it is part of a larger task). What we currently do is copy paste the task title into a subtask and delete the task.
Would be much easier to drag and hold on a task and allow to add it to the subtasks or even the notes.
To avoid mistakes, after dropping display confirmation for the action.
This will only work on tasks without subtasks or notes (so there is no data loss), pop notification if otherwise.
Good luch

Reordering sub-tasks is already in the works and has been released to Beta (for select users) on iOS :)
