Time management / personal planning service

Question

Please recommend a good time management (personal planning, todo list, GTD) service.

• It should be accessible from different platforms (at least Linux and Android), nevermind as responsive webapp like any Stack Exchange site or a set of native apps.

• I want to organize tasks using tags or categories.

• It should support configurable task deadlines and gentle reminders.

Answer 1

I use Trello exactly for the same reasons. Why I think it is a great application?

• You can create different tasklists and include tasks with deadlines and notifications
• You can add other users to the same board
• You have access from the website AND from an Android application
• The interface is really easy and user-friendly
• You can attach files on your tasks
• You have full control over who sees your boards. Plus all data is sent over a SSL/HTTPS connection, the same technology used by banks.
• It's free

Here is a screenshot from the interface:

Answer 2

All your requirements can be easily fulfilled with a GMail account and the GTasks Android application.

The TaskList can be accessed using any browser on desktop computers, by logging into your GMail account, and GTasks which is, in fact, a container for Gmail tasklist, can be used from mobile devices.

Some reasons for using this solution:

• it has a simple interface but completely functional;
• using the Google Tasks API you can handle the tasklist through your own fancy web application or to integrate it with other Google applications like Docs, Spreadsheets and Draw, to generate great reports! However, there is a limit for the API free using: you can do only 5,000 queries per day, from your built application.
