iPhone
The only todo app with a graveyard.
You don't need another todo list. You need consequences.
OneTh1ng only lets you have one task. Try to add another? The first one dies. Forever. No undo. No mercy. Just a graveyard of your abandoned intentions.
Leave a task too long? It decays. Neglect it for a week? Auto-deleted. Cause of death: you.
Simple. Brutal. Effective.
