You don't need another planner. You need fewer decisions. Crumple was built for the brain that freezes when the to-do list hits double digits. If you know task paralysis, executive dysfunction, or the guilt spiral of 47 unfinished tasks — this is the app that finally gets out of your way. ONE STICKY NOTE. ONE TASK. THAT'S IT. No boards. No categories. No color-coded priority matrix. Just a single bright sticker on a dark background. Brain dump what's on your mind — by voice or keyboard — and Crumple shows you one task at a time. Done? Drag the sticker to the corner and watch it crumple with a satisfying paper-crush sound and haptic pop. That tiny moment of destruction is your reward. WHY IT WORKS Traditional planners assume you can prioritize, organize, and execute in sequence. ADHD brains don't work that way. Crumple skips the planning and goes straight to doing: • Brain dump everything — get it out of your head, fast • See only ONE task — no overwhelm, no choice paralysis • Crumple it when done — instant dopamine hit • Voice input — talk instead of type when your brain moves faster than your thumbs • Home screen widget — your current task, always visible • No setup, no tutorials — open the app and go THE PLANNER YOU'LL ACTUALLY USE Most productivity apps are designed for people who are already productive. Crumple is for the rest of us — the ones who download a planner, set it up beautifully, and never open it again. One thing done is better than ten things planned.
