SmokeFree is a free Android widget developed by David Farre, aimed at helping people quit smoking. It does not have a launcher and can only be accessed by adding it as a widget on the main screen. Once added, the widget displays the number of days that have passed since the user quit smoking, as well as the amount of money the user has saved by not smoking.

The widget is simple and easy to use, making it a great tool for those who want to quit smoking. It provides a constant reminder of the user's progress and helps to keep them motivated. SmokeFree does not provide any additional features or resources for quitting smoking, but it serves as a helpful visual aid in the process.
