I am forced to remain with Todoist until an "every x interval after completion" recurring option is added to "every x internal" recurring pattern.
In other words, you need a "every" and an "after" option based on due date and completion dates respectively.

Just so the developers know, I, too, am not going to use this service due to it not having proper "every" and "after" task repeat options.
I would note though, that it seems that most developers of to-do manager's don't "get" this simple requirement (RTM and other older tools notwithstanding [I just wish they didn't get tied to their old UI's]).
