Find anything you own in seconds. Itemlist remembers where everything is, so you don't have to. Give every item a place once, then find it again the moment you need it. SEARCH THAT ACTUALLY FINDS THINGS Type whatever you remember: a name, a brand, a detail. Search matches across every field. Or scan a barcode to search your inventory. ORGANIZED LIKE REAL STORAGE Locations hold rooms, rooms hold containers, and containers nest inside other containers, as deep as your shelves actually go. The box inside the crate inside the closet is one search away. EVERY PLACE YOU KEEP THINGS Create a separate location for each place: your house, office, vacation home, storage unit. Each one keeps its own rooms, containers, and inventory, all in one app. SHARED WITH YOUR HOUSEHOLD OR TEAM Every location is shared separately: your family sees the house, your coworkers see the office, and nobody sees what isn't theirs. You control who can view and who can edit, and the location owner's PRO covers everyone in it. LENT IT OUT? MOVED IT "JUST FOR NOW"? With PRO, mark an item as lent and see who has it, or mark it as displaced and Itemlist remembers where it really is until it goes back. STOP RE-BUYING WHAT YOU ALREADY OWN A quick search tells you whether you already have one before you buy another. READY FOR THE BAD DAY TOO Photos, serial numbers, purchase prices, and condition on every item, with CSV export ready for an insurance claim, your business records, or your accountant. ON ALL YOUR DEVICES iPhone and iPad. Works offline and syncs across your devices. FREE TO START Up to 100 items and 20 containers free. PRO adds unlimited items and containers, location sharing, lending, and displaced tracking.
