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.

Not another to-do app. ParaCortex is for anyone who's stared at a task list and felt more stuck than when they started. Whether you have ADHD, suspect you might, or just find your brain works better with the right support โ€” this was built for you. We don't do "Overdue." We do Roll Forward. Tasks you didn't get to yesterday quietly carry forward to today. The ones you didn't finish this morning are still there this evening. No deadline labels. No shame spiral. Just your list, ready when you are. CAPTURE IN SECONDS Tap the mic and speak it. ParaCortex transcribes and saves your task before the thought disappears. No typing required. BREAK IT DOWN "Reply to emails" isn't a task. It's a wall. ParaCortex uses AI to break any goal into bite-sized micro-wins โ€” 5-minute steps you can actually start. MATCH YOUR ENERGY Every task has an Energy Cost: Low, Medium, or High. Each day, ParaCortex checks in โ€” how's your energy right now? โ€” and surfaces the one task that fits. No scrolling through a long list. Just the right thing for right now. FOCUS MODE When you're ready to begin, tap into a dedicated Focus screen. A circular countdown ring makes time feel tangible, not just countable. Pair it with built-in ambient audio โ€” brown noise, rain, lo-fi โ€” to create the conditions your brain actually needs to stay on task. YOU'RE NOT ALONE Body Doubling is the quiet magic of knowing others are working too. ParaCortex shows a live count of focusers in the room โ€” no chat, no pressure, just presence. STAY ON TASK, EVEN WHEN YOU LEAVE Your current micro-win stays visible on your Home Screen, Lock Screen, and Dynamic Island. Out of sight shouldn't mean out of mind. GENTLE REMINDERS, NOT ALARMS Nudges arrive at natural transitions in your day โ€” not as deadline warnings, but as open invitations to begin. CELEBRATE FOR REAL Every secured win triggers a full-screen celebration โ€” confetti, balloons, fireworks, and more. Your brain deserves the dopamine hit. ParaCortex isn't about doing more. It's about feeling less stuck โ€” one small win at a time.
