–minutes focused
“I have so many ideas, and I do get things done. But carrying them all at once was exhausting. One session at a time, the work feels lighter. And I feel much more focused.”Jason, maker of Focussed One
Made for ADHD brains.
Not another rigid productivity system. A gentle, forgiving tool that celebrates effort and works with how your brain actually runs.
Zero friction
Starting is the hardest part for an ADHD brain, so we make it tiny. Pick a few minutes (from a 30-second taste to a full hour) and hit go. Once you’re moving, momentum takes over, and you can always add more time.
Rewards that stick
Your brain chases the reward that’s right now, not the one far away. So every minute earns Focus Points the instant you stop, and your next badge stays in sight, turning effort into a payoff you actually feel.
Visible momentum
Time blindness is real: effort fades from memory the moment it’s done. So two GitHub-style heatmaps (focus in blue, tasks in purple) put a whole year of it where you can see it, and momentum becomes something you watch grow instead of something you have to remember.
Brain-friendly capture
Working memory drops things fast, so don’t keep them in your head. Toss every stray thought into a “Someday” list where nothing gets lost, keep one active project in front of you, and sort the rest when your head is clearer.
Built-in dopamine
Finish, and something good is waiting, never the same thing twice: a quote, a mindful pause, a joke, a fun fact, or a piece of generative art, plus confetti and your Focus Points. That hit of novelty wires the good feeling to finishing, which is what makes the next session easier to start.
No shame, no pressure
Shame makes you avoid the thing, so nothing here punishes a missed day. Streaks celebrate, they don’t scold. Stats show what you did, not what you didn’t, and an off morning is just a morning, with your work still there waiting.
A note from the maker
Hi, I’m Jason. I built Focussed One because my ADHD kept stalling my progress, or pushing me to rush without purpose.
Now I can focus and finish tasks without dread. My effectiveness has accelerated, and I can finally concentrate, drill down, and chase my wildest dreams. I hope it does the same for you.
