Put it away. Find it later. Just say where you put something — "the charger is in the kitchen junk drawer" — and WhereMate files the thing and the place. Months later, ask, and see the place, the photo and your note. • Say it, type it, or snap a photo. One sentence is enough. • Find anything fast: the place first, then the box, the photo and your note. • Every save shows what was saved, with Undo and one-tap fixes. • Places hold boxes, and boxes hold things. Know what's in every box. • Print a QR label for any box, or save it as a PDF. Scan the label with WhereMate to see inside. • Made for iPhone and iPad, in Light or Dark. Private by design Your library stays on your device. No account, no ads, no tracking, and nothing is sent to us. Speech and photo recognition run on your device. On supported devices, Apple's on-device language model helps understand what you said; everywhere else WhereMate's own rules do the same job, on your device. Simple pricing Free for your first 5 things. One purchase unlocks unlimited things and every label design. No subscription. If you used WhereMate before version 6.0, unlimited things stay free for you.
