One feature I always wanted calendars/todo apps to have is support for repetitive tasks.

For example - say I need to service the car every year so I create a corresponding repeating event in my calendar. However, at some point I decide to service the car a couple of months sooner or later than planned. Now, the events are out of sync and I have to reschedule the whole series so it doesn't drift. Or, if I'm past the planned servicing time, I don't see the event at all and may forget about it.

What I'd like to be able to do is to create a repetitive todo that pops up again a certain time AFTER THE LAST TIME I COMPLETED IT. I serviced the car a month ahead of time? I complete the task, and the next occurrence will also move up by a month. I was on vacation when the car had to be serviced? The todo is still there, and the next occurrence will also be pushed back.

The only app that does this right I know is Things 3[1] by Cultured Code.

Many todo apps do this including Things 3 and OmniFocus. What you want is a task that recurs on completion as opposed to one that recurs on a schedule.

Todoist allows you to to create a repetitive tasks (that restarts the clock after task completion) by typing "every!" with an exclamation mark.

TickTick does this, best todo app I've ever used.

Toodledo.com does this. I know because I made Toodledo, although I no longer own it.
