Review - Web based task managers.

Remember The Milk

Doesn't let you add sub tasks.
Adding notes takes three clicks! (Select tasks, Notes Tab, Save)
Doesn't show completed tasks on the same page! (Isn't that feeling of seeing completed tasks what we need?)
Let's you tag them. That's a great feature. But it won't work for me. I don't have that many tasks.
Lists is a great feature.
Priorities is a great feature.

Flowy

Not free!

Todoist

Doesn't let you add notes.

hiTask

It's just too much! Definitly not for me. I need something minimalist.
This will definitely be the starting point, if I started developing one. It has a very intuitive interface  A little less intuitive though.

Tada List

Too simple. Google tasks is much better than this. I like this, but sub tasks and notes functionality missing.

Todo.ly

Doesn't let you add notes in the free version. Also, too busy.

Narvana

So far so good. All the features I want. Plus it follows GTD. But it doesn't have sub tasks. A little too advanced though. Whatever.

Doit.im

So far so good. All the features I want. Plus it follows GTD. But it doesn't have sub tasks. A little too advanced though. Whatever.

Winner: Asana! by far the best Task Management, Team Management software. And Free. And has everything. Hadn't tried it while doing this research, discovered it later.
