I ask for advice in choosing an application for GTD on Windows Phone 8.1?

Question

Time Management

Hi guys!
The essence is clear from the title, so I will voice the requirements.
Requirements:
Synchronization with the cloud
Web muzzle
Repeating reminders
Contexts or tags
Projects, subprojects, in short - a tree structure
Pleasant, not overloaded interface
Thank you!

Answer 1

I use Chaos Control, I haven't found a better one yet.

Answer 2

Wunderlist is very handy.
I have GTD organized by principle in my personal folder there are separate lists

1. incoming
   
2. priority steps
   
3. expectation
   
4. calendar
   
5. someday maybe
   

• It is convenient to use hashtags to indicate kairos, the time that the case will take and the project to which it belongs.
  
• It's great that you can open both on the web and in the application on macbook, ipad, android.
  
• The recurring case system is not very flexible, but it works for most cases. For example, you can make a case that repeats at a certain frequency, but it seems that it will not work to set up a case that reappears N days after the completion of this case.
  
• Lists can be shared with other people.
  
• The tree structure is weak. There are folders, folders have lists, lists have tasks, tasks have sub-items. For example, folders cannot be pushed into folders.
