Todo Q v1.2.0 has been released on the android market. The latest version adds support for repeating tasks with daily, weekly, weekday, monthly, and yearly periods.
We also recently released Todo Q Free, which is a time-limited version of Todo Q v1.1.28. (w/o repeating tasks)
Here's a shot of the repeat selection menu.
Future ideas include a custom item with support for end duration, particular days, etc. Working towards supporting more of the iCalendar specification.
Thanks for all the great input on this feature.
