Finishing a task should feel like something.
Crumple is a deliberately tiny task app for ADHD brains. No streaks. No guilt. Just sticky notes you crumple the moment you're done — the little hit of dopamine our brains actually need.
Most task apps punish you. This one rewards you.
ADHD brains run on immediate reward. A quiet checkbox does nothing. Streaks just become one more thing to fail. Crumple makes "done" a moment you can feel.
Crumple = done
Finish a task and physically crush the sticky note — a satisfying, tactile little win, every single time.
No streaks, no guilt
Miss a day? Nothing breaks. There's no streak to protect and no shame engine. You just pick up where you are.
Deliberately tiny
Not another overwhelming productivity system. Sticky notes you crumple. That's the whole idea — on purpose.
Hi, I'm Denis.
I'm a clinical psychologist with a PhD — and I live with ADHD myself. I kept reaching for task apps that were built for neurotypical brains and quietly made mine feel worse. So I started building the tools I actually wished existed.
