Where are the Christmas decorations? The passport? The winter tires? Fundibus remembers where your things are at home – and finds them again before you dig through the basement. JUST SAY IT Tap the big button and speak: “The skis are under the bed.” Fundibus understands the item and the place, saves both, and is ready for the next one two seconds later. Perfect when your hands are full. ASK SIRI “Hey Siri, where is my laptop in Fundibus?” – Siri answers with the place, even from the lock screen. And “Hey Siri, remember something in Fundibus” saves an item without opening the app. FIND IT AT A GLANCE Every place gets its own color. Basement, garage, sofa: Fundibus groups things automatically, so you see what’s where in a second. Add a photo and the app even suggests the name. SHARE THE LIST One list for the whole family: invite others via iCloud, everyone sees and adds the same things. Whoever put the drill away last writes it down – and everyone finds it. ALWAYS WITHIN REACH Control Center, Lock Screen, Action button or Back Tap: quick capture is always one gesture away. Your things also show up in iPhone search. YOUR DATA IS YOURS No sign-up, no account, no ads. Everything lives on your iPhone and in your iCloud. Speech and image understanding run on the device. Only for some languages does Apple’s cloud help with speech recognition, and Apple keeps nothing of it. Say it once. Know it always.
