Most to-do apps solve the wrong problem. They help you collect more tasks, not finish them. ThatOneThing does one thing differently: every day, you pick a single task that matters, and you finish it before you're allowed to add another. That's the whole idea. No backlog staring back at you. No twelve half-finished projects competing for your attention. Just today's one thing, front and center, until it's done. It works especially well if you've got ADHD, or you just find long lists overwhelming no matter what. Built to keep you coming back Finishing your one thing builds a streak, and streaks are protected: miss a day here and there and a shield covers it, so one bad day doesn't wipe out three weeks of work. Every completion earns XP, XP adds up to levels, and leveling up reveals more of a 34-badge collection, from your first finish to a full year of showing up. See the proof Your Done list keeps a running record of everything you've actually finished, not just what you meant to do. Watch your all-time count climb. Look back at last Tuesday and see exactly what got done and when. Make it yours (Premium) Pick an accent color, choose from several app icons, and set a custom background or font for your focus card. Premium also adds multiple active tasks for the days you genuinely need more than one, your full stats history, and streak shields. Everything else you'd expect A home screen widget shows today's one thing at a glance. Reminders nudge you at the time you choose. Dark mode, VoiceOver support, and 34 languages are built in, and your data syncs across devices with iCloud. If you're tired of a list that never finishes itself, start with one thing today.
