ADHD Focus

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.

Just One - One task at a time. Most productivity apps give you more to manage. Just One does the opposite. You choose one task. You finish it. Only then can you start the next. No lists. No juggling. No overwhelm. ------ HOW IT WORKS 1. Set your one thing - Decide what matters right now and commit to it. 2. Stay focused - Your task stays on screen. You cannot create a new one until it is done. 3. Finish and move on - Mark it complete, then choose your next focus. 4. Be honest with yourself - Did not finish? Carry it forward or let it go, but you have to decide. ------ FEATURES * One task at a time * Daily focus screen * Streak tracking * Calendar view * Progress tracking * Light and dark mode * Adjustable text size * No account required ------ BUILT FOR * People who feel overwhelmed by to-do lists * People who start but struggle to finish * People who want clarity, not complexity ------ NOT FOR * Complex project management * Team collaboration * Full task lists and planning systems ------ PRIVACY Your data stays on your device.

Verdict
The clearest difference is in-app purchases: Just One at none against ADHD Focus's 2. Just One also leads on update cadence (daily vs every 3 days) and iOS requirement (15.6 vs 17.0). On price, ads and device support there is nothing between them.
