A GUI countdown timer written in Python using the Tkinter framework.

The timer has been tested on Ubuntu 14.04 with the following versions of Python.

• Python 2.7.6
• Python 3.5.2
• Python 3.4.3

But it should work on macOS and Windows. Please report any issues you experience on these platforms!

Features

• Add multiple timers
• Add labels to each timer
• Simple scrolling to increase the value of each timer.

Execution

As simple as:

python timer.py

Setting Time

1. Scroll over the seconds, minutes or hours while the timer is paused to set each.
2. Click on the timer to pause/start it.

TODO / Known Issues

• Need to build in time correction (ticker might be off by a few miliseconds, and that adds up)
• Notifications using pynotify
