You know the drill: bricks everywhere, a smudged paper list, and you're hunting the same tiny plate in the same color for the third time. BrickPartManager is your part list in your pocket. Tap instead of scribble — see instantly what's still missing and what's already in the bin. Works offline when the Wi‑Fi doesn't reach the basement. Sorting multiple sets? One master list shows every missing part — filter by color, sort your way, no flipping between sheets of paper. On iPad, the large grid keeps dozens of parts visible at once, right beside your sorting trays. Building with someone else? Premium lets you invite them with a code — everyone ticks off live. No more "did you already find that one?" for the tenth time. Already use Rebrickable? Premium imports your lists instead of typing everything again. Try it free without an account — one set, no signup needed. Free · User · Fan · Premium — monthly subscriptions, cancel anytime in iOS Settings. Not an official LEGO® product.
