Linux Pomodoro timer

README.md

pomodoro.sh

A pomodoro timer for Linux-like systems.

Highly inspired by Pomtify

Advantages

• Stops/pauses music remotely, so it overcomes mobile music playback security limitations
• Demands user interaction with periodic notifications to confirm that you really finished work/rest

Disadvantages

• Developing this tool actually decreases my productivity

Requirements

• bash
• spotify-tui
• speech-dispatcher (make sure you also installed espeak-ng and/or festival, and ran spd-conf)

Features

• Play/pause Spotify for breaks
• Say it loud
• Wait for user interaction after focus/break
