I’m very excited to announce the release of my first mobile app – the Rebrickable LEGO Shopper.

The app is a LEGO shopping companion and it can help you decide if you should buy a particular LEGO set, or at least which LEGO set you should buy. Simply scan the barcode on a LEGO box (or enter it’s set number manually) and it will display several tabs of information to help you, some of which is new content not even available on Rebrickable.

Set Info

See the % of parts you already own in this set. If it’s a very high number you probably don’t need to buy it and might prefer to source the missing parts instead. This will use all your existing saved Build defaults and sets/parts list configuration.

Set Prices

See the known prices at other locations (for now only Amazon and LEGO.com with links to BrickLink etc). Useful to get a feel for any “specials” the store might be claiming. I'm hoping to add more data sources to this shortly.

Part Prices

Based on hundreds of BrickOwl stores, the average prices for each part is added together to get an overall "part-out" price of the set. Useful if you are into that sort of thing.

Alt Builds

A list of all the alternate build MOCs we have for the set. More MOCs = more value :)

Rare Parts

See which parts in the set are rare. Currently, this means a part appears in 3 sets or less for that color.

Valuable Parts

Lists the top 10 most valuable parts within the set, again based on BrickOwl store prices.

What If?

This tab answers the question – what else can I build if I buy this set? In addition to the list of alt builds on the other tab, it will re-calculate your owned part % for every single set and show you which ones get the biggest improvements.

Some features require you to login to Rebrickable to work, but if for some crazy reason you don’t have an account the remaining features will work fine.

Is it Free?

So far everything on Rebrickable has been free, however I decided to release this as a paid app with no ads. Initially I've set it to USD $1.39 which at current conversion rates and after Google's 30% cut, means I make about one dollar per install.

This is where I ask you to please support both Rebrickable and myself and give the app a go! I've poured my life into Rebrickable over the last 4 years (just ask my wife!), and would love to see some of that effort reflected in a successful app.


I’m always happy to hear feedback or suggestions anyone might have. I’ve just created a new forum for the app, or if you prefer to leave anonymous feedback go here. If you do like the app, I’d love to get a 5 star review on the Google Play Store. These ratings are essential for an app to stand any chance of becoming visible to general audiences through store or category listings. If you find a bug or issue please let me know via the forum/feedback and I'll do my best to fix it as soon as possible. I'm happy to hear feature suggestions too.

Of course, over time you can expect the functionality to grow and make the most of available features on Rebrickable as they are implemented.


It is currently available on Android, and if successful I will release it on iOS and Windows.

Go to the Google Play Store

Update 20/01/2016: I've got an iOS app working and ready to go, but Apple's rules for Australian businesses are incredibly annoying and I'll have to figure out the tax implications before I can do anything more. Of course, this was after I paid their $149 annual fee.
