Recurrent Tasks for Google Tasks
Project RecGTasks was created as a workaround in order to achieve missing functionality of repeating/recurrent tasks in Google Tasks. As mentioned - it is just a workaround, but it's WORKING :-)
How does it work
Solution consists of Google Apps script running every day at 1am (according to user's time-zone). Script creates occurrences of tasks in a specified destination task list. You can use several task list for separating your home, family and e.g. work tasks.
