nnCron understands cron table format (Unix) and is managed with easy-to-edit plain text crontab files. However, for those who prefer to work in a GUI environment, the program has a graphical shell which can be used to remove, add, edit and run tasks, set up reminders, change program settings.

nnCron has its own powerful (Forth-compatible) scripting language, allows to use VBScript/JScript, as well as regular expressions, and can be further extended with plugins. It can be started as a service or as a regular standalone application. You can examine nnCron features in depth by reading it's online documentation.
