Yes, mostly because it stops you forgetting. A week after you clear a shelf, the shelf just looks normal. The effort disappears. A number doesn't.
Declutter Quest keeps one big total on the home screen: everything you've removed, ever. Under it sits the split between thrown, sold, donated and recycled, plus the last five things you logged. The little message above the total changes as it grows, from "Great start!" to "You're on a roll!" and onwards.
I built it this way because the usual advice (do a little every day) only works if you can see the little bits adding up. Thirty items over a month feels like nothing while you're doing it. Seeing "30" feels different. Seeing 300 by spring is very different.
Tracking also swaps a vague feeling for an honest record. Some weeks you'll log two items. That's fine. It's still not zero, and the total only goes one way.
