Ever bought something that came with spare parts — screws, cables, an extra bracket — put them in a drawer "just in case," and had no idea where they ended up two years later? Nookify remembers so you don't have to. How it works • Add an item with a photo and place it anywhere — a shelf, a drawer, a box, a garage cabinet. • Nest locations exactly the way your space really works: Garage → Shelf 2 → Red Box → TV Mount Screws. • Move a box, and everything inside it moves with it automatically — no need to update each item one by one. • Search by name and see the full path instantly — exactly where to look, not just a name. Why it keeps working • Every move is logged automatically, for both items and whole containers — trace where something used to be. • Works fully offline. No account, no sign-up — your data backs up quietly through your device's own iCloud. • One-time purchase, no subscription. Pay once for unlimited items, keep it forever. Built for garages, closets, storage units, moving boxes, and hobby rooms — anywhere you've ever said "I know I still have that, somewhere." Free to start, with a one-time purchase to go unlimited — no subscription, ever.
