ADHD Focus: That One Thing
Daily Task Tracker & Streak
Free · In-App Purchases
Pick one task, finish it, watch your streak grow. On iPhone, iPad and Mac, always in sync, and now much lighter on battery.
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.
A real Mac app
Not a stretched-up phone app. There is a proper sidebar, real menu bar commands and keyboard shortcuts. A menu bar item sits up next to the clock showing today's one thing, and one click finishes it without opening the window at all. Prefer it out of the Dock? Run it from the menu bar alone.
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 levelling 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. Stats show a 30-day consistency view and a weekly recap of what got done.
Make it yours (Premium)
Pick an accent colour, 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
Reminders nudge you at the time you choose. Dark mode, VoiceOver support and 34 languages are built in. Your things, your streak and your XP sync with your iPhone and iPad over iCloud, so the one thing you set on your Mac is the one waiting on your phone.
If you're tired of a list that never finishes itself, start with one thing today.

Ratings & Reviews
- This app has not received enough ratings or reviews to display an overview.
This update is about speed and battery life.
The Mac app kept working in the background even when you were not using it, which meant constant CPU load and a warm laptop. While idle it now sits at zero.
Some people saw the app freeze, or get shut down by the system, shortly after opening it. The work behind that has moved off the launch path, so the app also starts faster.
On Mac, Settings now keeps its close button pinned at the top, so you can close the window without scrolling back up.
Your things, your streak and your XP are unchanged. Same app, easier on your machine.
