OneTh1ng vs First Thingy

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.

Most productivity apps give you more ways to make longer lists. One Thing gives you one task. Set the one thing that matters most right now. Work on it. When you're done, mark it complete. If you give up, you have to say why — in your own words, saved permanently. That's it. Why only one task? Because you can only do one thing at a time anyway. The list is the lie. One Thing removes the lie. Why must you explain yourself? Because excuses are easy when no one is watching. One Thing is watching. Not to judge — to help you see the patterns you hide from yourself.
