The LEGO hobby has exploded in the past few years, and the app ecosystem has grown with it. There are now more tools than ever for tracking your collection, identifying sets, checking prices, and managing your brick investment. The problem is not a lack of options. The problem is figuring out which app actually does what you need without wasting time on tools that look promising but fall short.
I have used every major LEGO inventory app available in 2026. Some I have used for years. One I built myself. This is an honest comparison of the five most popular options, with real opinions about what works, what does not, and which app is worth your time depending on how you collect.
The apps in this comparison are GameSetBrick, BrickIt, BrickSearch, Rebrickable, and the Brickset app. Each one takes a different approach to the same core problem: managing your LEGO life.
GameSetBrick is a Progressive Web App built specifically for LEGO collectors who want collection tracking, market pricing, and deal analysis in one place. Full disclosure - I built it. But I built it because nothing else combined these features, and after months of daily use I stand behind that assessment.
Collection tracking: The Vault lets you log every set you own with purchase price, condition (sealed, built complete, built incomplete), and date acquired. It tracks total collection value using live BrickLink market data and calculates ROI per set and across your portfolio.
Market data: Every set shows current new and used market prices pulled from BrickLink sales. The deal score rates any price from 0 to 100 so you instantly know if a deal is worth taking. Price history sparklines show value trends over time.
Discovery tools: The barcode scanner identifies sets instantly. The Flip Finder surfaces sets approaching retirement with the highest resale potential. The GWP tracker monitors Gift With Purchase promotions.
Sharing: Wishlists can be built and shared via link with buy buttons for gift givers. CSV export lets you download your entire collection for backup or insurance documentation.
Platform: PWA that works in any browser. Add to home screen on iPhone or Android and it behaves like a native app. No app store required.
Price: Free to use. No subscription. No premium tier. Revenue comes from affiliate links when users click through to buy sets.
Best for: Collectors who want everything in one tool - tracking, pricing, deals, and sharing. Especially strong for in-store use thanks to the barcode scanner and deal scores.
BrickIt made a big splash with its headline feature: dump a pile of loose LEGO bricks on a table, point your phone camera at them, and the app identifies individual pieces and suggests builds you can make from what you have. It is genuinely impressive technology and it solves a real problem for anyone with bins of unsorted bricks.
Parts identification: The AI camera feature works surprisingly well. It is not perfect - small pieces, unusual colors, and overlapping bricks can trip it up - but it correctly identifies the majority of standard pieces. For someone trying to sort a bulk lot or figure out what they can build from a mixed bin, this is a game changer.
Build suggestions: After scanning your pile, BrickIt suggests official LEGO sets or MOC designs you can build using the identified pieces. It even generates step-by-step instructions for some builds. This is the feature that separates BrickIt from everything else on this list.
Collection tracking: BrickIt has added set-level collection tracking, but it is secondary to the parts-focused features. You can mark sets as owned, but the tracking lacks depth - no purchase prices, no market values, no ROI calculations.
Market data: Limited. BrickIt is not a market tool. It does not show secondary market prices, deal scores, or price histories.
Price: Free basic version. Premium subscription unlocks additional features including more build suggestions and enhanced scanning.
Best for: People with bulk brick collections who want to identify pieces and discover what they can build. Not ideal for set collectors focused on values and investments.
BrickSearch is a mobile app focused on quick set identification and basic information. Point the camera at a LEGO box or type a set number, and it pulls up details including piece count, theme, year, and retail price. It is clean and fast.
Set identification: The barcode scanner works well for in-store use. It reads UPC codes and pulls set data quickly. The interface is clean and the results are easy to read on a phone screen.
Collection tracking: Basic. You can mark sets as owned, but there is no purchase price tracking, no condition logging, and no portfolio valuation.
Market data: BrickSearch shows some pricing information but does not offer the depth of BrickLink market data, deal scoring, or price history that more specialized tools provide.
Price: Free with ads. Premium version removes ads and adds some features.
Best for: Quick in-store lookups if you do not need market pricing or collection management. It does one thing and does it simply.
Rebrickable is the gold standard for parts-level LEGO data. If you build MOCs (My Own Creations), Rebrickable is essential. It catalogs every LEGO element ever produced, tracks which sets contain which parts, and lets you figure out exactly which sets to buy or part out to get the pieces you need for a custom build.
Parts inventory: Unmatched. Rebrickable knows every element number, every color variation, and every set that contains each part. You can enter your collection and it calculates which MOC designs you can build with parts you already own.
MOC database: Thousands of community-created MOC designs with parts lists and building instructions. This is where MOC builders plan their projects.
Collection tracking: Set-level and parts-level tracking. You can log sets you own and Rebrickable automatically calculates your total parts inventory. This is invaluable for MOC planning but less useful for collectors focused on set values.
Market data: Rebrickable does not provide market pricing. It is a parts and building tool, not a financial tool.
Price: Free basic access. Premium subscription adds enhanced features and API access.
Best for: MOC builders who need parts-level inventory management. If you build custom creations and need to know what pieces you have and what you need, Rebrickable is irreplaceable. For set collectors, it is less relevant.
Brickset's mobile app is an extension of the Brickset website, which is the most comprehensive LEGO set database in existence. The app gives you access to set information, basic collection tracking, and the Brickset community from your phone.
Set database: The deepest and most complete set database available. Every set from every year, including obscure promotional releases and regional exclusives. If a set exists, Brickset knows about it.
Collection tracking: Mark sets as owned or wanted with quantities. The app syncs with your Brickset account so your collection is consistent between phone and desktop. However, there is no purchase price tracking, no condition logging, and no portfolio valuation.
Market data: None. Brickset shows retail prices but not secondary market values. You cannot check what a retired set is selling for today.
Community: Access to Brickset forums, set reviews, and news. The community aspect is stronger than any other app on this list.
Price: Free with optional supporter subscription for ad-free experience and some extra features.
Best for: Researchers and long-time collectors who want the deepest possible set database. Less useful for price checking, deal evaluation, or investment tracking.

If you are a set collector who buys, tracks, and values LEGO sets: GameSetBrick is your primary tool. It handles the full lifecycle from discovery to purchase to tracking to valuation. Pair it with Brickset for deep set research when you need historical information.
If you are a MOC builder who works with loose parts: Rebrickable is essential for parts inventory and build planning. BrickIt is a great companion for sorting bulk lots. GameSetBrick can still help you track the sets you buy for parts and monitor market values.
If you are an investor focused on buy-and-hold LEGO sets: GameSetBrick's Vault, ROI tracking, and Flip Finder are built for you. Combine it with BrickEconomy for long-term price chart analysis. Read our LEGO Investing 101 guide for the full strategy.

The LEGO app landscape in 2026 is better than it has ever been. The right combination of tools depends on how you collect. But if you are picking one place to start, GameSetBrick gives you the widest coverage for zero cost. Everything else is a complement to that foundation.
