wow, this is surreal as I was just about to start and IDENTICAL project for my next ios app - scanning messy room -> checklist -> progressbar -> split the checklist into steps. Then: one step visible at a time, so the user has only one thing to focus on and it seems more manageable. And upon finishing the step - CONFETTI! Addressing the ADHD part too. We have the same brain. I guess I'll skip this idea as I thought it was totally original :)
