This adds very basic support for Pomodoro technique in Emacs' org-mode.

With default options:

You can start a pomodoro for the task at point or select one of the last tasks that you clocked time for. Each clocked-in pomodoro starts a timer of 25 minutes and after each pomodoro a break timer of 5 minutes is started automatically. Every 4 breaks a long break is started with 20 minutes. All values are customizable.

Install from MELPA:

• Add MELPA to your EMACS installation:

    (add-to-list 'package-archives
                 '("melpa" . "https://melpa.org/packages/") t)
  

• Install the package via M-x package-install RET org-pomodoro

1. Move point to a task as you would do with org-clock-in. Call org-pomodoro the task will be clocked-in.
2. When there's time for break, the task will be org-clock-out'ed
3. If you call org-pomodoro during a pomodoro, you'll be asked to reset a pomodoro.
4. If you call org-pomodoro outside org-mode, you'll be presented with list of recent tasks, as C-u org-clock-in would.

Most aspects of org-pomodoro can be customized. Examples are the length of pomodoros and breaks (org-pomodoro-length, org-pomodoro-short-break-length, org-pomodoro-long-break-length), sounds, modeline display, if breaks should be clocked (org-pomodoro-clock-break) the behaviour when a pomodoro is reset (org-pomodoro-ask-upon-killing, org-pomodoro-keep-killed-time) etc. Have a look at the org-pomodoro customization group.

Some workflows benefit from the option to work a few minutes “overtime” to finish a task before taking a break (that is, a slightly dynamic pomodoro time). The option org-pomodoro-manual-break enables this workflow, where a break notification is sent at the end of the pomodoro time but the break is started first when manually calling org-pomodoro.
