Are there any other good task/reminder apps besides gTask and Email To Self? I'm using AKNotepad, which is quick and easy, but doesn't have reminders.

I need something to remind me to do stuff, bugging me every day until I do it, or just bugging me every day to remind me. I used to abuse my calendar with recurring reminders, but that's just not the right use. Is there any apps which can do this? Sorry my request is vague... it's tough to define what I'm after.

Thanks.
