Chunking: the actual idea behind this app
Not a growth hack. A real concept from cognitive psychology, applied to one specific kind of overwhelm.
Why is Chunkable called that?
"Chunking" is a real term from cognitive psychology, not a name invented for branding. In 1956, psychologist George Miller published a paper on how short-term memory handles information: not as one long string, but in small clusters, or "chunks," that are easier to hold in mind at once. A 12-digit number is hard to keep straight; the same 12 digits split into three groups of four are much easier.
The same idea applies to a task. A big, vague to-do overwhelms for a similar reason a 12-digit number does: there's too much to hold in mind at once to see where to start. Break it into pieces small enough to actually hold in your head, and it stops being too big to start. That's the entire mechanic this app is built around, nothing more exotic than that.

The four steps
- Dump it in, however messy. There's no structure to get right first, so there's nothing to get wrong.
- Chunkable breaks it into a short, editable checklist, each piece small enough to actually hold in mind.
- Work one step at a time with a live countdown running, so the next few minutes have a shape instead of vanishing.
- Check it off. That's the whole feedback loop: no points to earn, no streak to lose, nothing to protect on a bad day.
Why is Chunkable built this way?
Not just what it does, the actual research each choice traces back to.
One decision at a time
Every screen asks for exactly one decision, never a wall of settings before you can start. A 2025 study found 82% of adults with ADHD report regular difficulty with decision-making, and it gets worse under time pressure, not better. Fewer choices, less friction to actually begin.
Time made visible, not just measured
A live countdown, not a bare number sitting in a corner. A 2022 meta-analysis of 55 studies found ADHD adults have a measurably different sense of time passing, so a plan that only exists as small text is easy to quietly fall behind on. Watching the time itself keeps it real.
No points, no badges, no streaks
It would be easy to bolt on a streak counter. A meta-analysis of 128 studies found reward-for-completion systems can undermine the motivation to keep going once the reward is gone, while plain positive feedback doesn't. So checking off a step gives you exactly that: quiet feedback, nothing to protect.
Every open is a fresh one
Miss a day, a week, whatever, and nothing here shows you a wall of what you missed. Research on habit restarts backs this directly: people are measurably more likely to actually try again right after a natural reset point than mid-slump. No streak to have broken, just today's brain dump box.

Questions about the method
Is "chunking" a real psychology term, or just a name?
Real term. It comes from a 1956 paper by psychologist George Miller on how short-term memory handles information in small groups instead of one long string. The app is named after the actual mechanic, not the other way around.
Why doesn't Chunkable have streaks, points, or badges?
Because the research on reward-for-completion systems isn't kind to them: a large meta-analysis found they can undermine the motivation to keep going once the reward is gone, while plain positive feedback doesn't. Checking off a step gives you quiet feedback and nothing to protect, so there's nothing to lose on a bad day either.
Is this based on real research, or just one person's method?
It's built from two things: analysis of thousands of real reviews across dozens of ADHD and task apps (see the evidence section on the homepage), and the peer-reviewed research cited on this page. No single person's personal routine is the basis for how this app works.
Do I need to know any of this to use the app?
No. None of this is required reading, it's just the reasoning if you're curious why it's built this way. The app itself is just a brain-dump box.
The next thing to do doesn't have to feel this big.
One honest payment, forever. Your list doesn't disappear when you check a box.
