Tripaloo
Family trips run on two operating systems: parents need logistics, kids need magic. Most travel apps serve only the first. Tripaloo was designed for both at once, so the same screen that holds the budget also holds a unicorn.
For the parents: itinerary, budget, packing, places, journal, documents and calculators. For Alma: math and English games, flags, memory, drawing board, songs, stories, a wardrobe, an album, and a 3D unicorn pet that lives in the phone. All built as a fast offline friendly PWA that works in airplane mode. Literally.
The app flew on a real family trip and came back with memories inside it. This case shows the house superpower: obsessive attention to the smallest user. If we sweat the details for one seven year old, imagine what your customers get.
