Brikr is the LEGO® collection app built for serious collectors. Track every set you own, monitor market values, discover deals, and share your own custom builds with the community. MANAGE YOUR COLLECTION Add sets by scanning a barcode, searching by name, or snapping a photo. Track condition (New or Used), view current secondary market prices alongside MSRP, add personal notes, and sync everything across all your Apple devices automatically. KNOW WHAT IT'S WORTH — BRIKR PRO Turn your collection into a financial dashboard. See total collection value, per-set pricing, ROI leaders, appreciation trends, and future value projections. Get weekly price alerts when any set in your collection moves 10% or more. Export your full collection as a formatted PDF. CAN I BUILD IT? Find out whether you have enough parts to build any set — or any community MOC. Brikr compares your parts inventory against what you need, shows your completion percentage, and lists exactly what's missing with images and quantities. COMMUNITY MOC GALLERY Browse original custom builds submitted by the Brikr community. Sort by name, year, or piece count. Tap any part for its full detail. Submit your own MOC with a cover photo, your Studio design file, and build instructions — approved builds join the gallery with full builder credit and a downloadable instructions PDF. BRIKR AI — BETA Ask your collection anything in plain language. "What Star Wars sets do I own?" "What parts come with the Millennium Falcon?" "What's my most valuable set?" "What Technic sets released in 2023?" Brikr AI searches your collection, wishlist, and the full LEGO® catalog — sets, parts, themes, retirement status, and more. Your conversation history saves automatically so you can pick up where you left off. Free users get 5 questions a day; Brikr Pro unlocks unlimited questions, per-set pricing answers, and a cloud AI fallback for complex queries. Requires iOS 26 and an Apple Intelligence-capable device. GAMES & LEADERBOARDS Test your knowledge in Fig Blitz, Parts# Blitz, and Minifig Identifier. Compete on global leaderboards.

Read full description

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. WhichBrick offers an auto-renewable subscription: $1.99/month (or $14.99/year), or a one-time $39.99 Lifetime purchase, each unlocking unlimited sets. Payment is charged to your Apple ID; a subscription auto-renews unless canceled at least 24 hours before the period ends.

Verdict

The call

The clearest difference is ads: WhichBrick at none against Brikr's shown. WhichBrick also leads on iOS requirement (15.0 vs 18.2). Brikr's advantage is update cadence (every 5 days vs fortnightly) and ratings volume (5 vs 1). On price, rating, review sentiment and in-app purchases there is nothing between them.
