WhichBrick is a friendly brick-building companion for kids and families. Add the sets you own, browse big photos, tap into parts, and quickly answer the question that always comes up during a build: which brick do we need? Made for young builders, WhichBrick keeps things simple: large tap targets, visual browsing, minimal text, and parent-managed sign-in. Kids can explore their sets, search for parts, meet the minifigures from their sets, star favorites, and save notes without digging through a grown-up collection spreadsheet. When a piece goes missing, WhichBrick helps you look across your collection to see where that part appears in other sets. It is a practical way to rescue a build without dumping every bin on the floor. WhichBrick also helps turn the sets you already have into new ideas. From a selected set, find available alternate builds and MOCs, then save favorites for later. The app uses Rebrickable catalog data so your collection stays useful, searchable, and fun to explore. Features: - Add sets by set number or search - Browse owned sets with clear images - See each set's parts grouped by color - Search parts across your collection - Find which sets contain a part - Browse the minifigures in your sets - Filter by theme, set, color, and more - Discover alternate builds and MOCs - Star favorite sets, parts, minifigures, and builds - Add notes to favorites - Sync your collection across devices Every feature is free for up to 10 sets. A subscription lets you add more than 10 sets. WhichBrick is for kids, but a parent or guardian sets up and manages the account. WhichBrick is not affiliated with or endorsed by the LEGO Group.
