I love it but need 3D models for larger builds like 2000+ pieces

I bought the Liebeherr crane and was so disappointed that there was no LEGO 3D model for it in the builder app… sigh…. Also same thing with the grand piano… I hope every LEGO set from 2026 forward has a 3D building instruction to accompany it

maybe

oh like maybe well meet in a bar well drive a funky ehh i think oliver tree made that song

new app update is horrible

this app used to be useful for seeing all your stats and sets, everything organized and easy to use. now it looks like a mess, it's hard to use, hard to see your sets, and can no longer click on any of your stats. you can barely see any of your sets from the main interface on a phone and even then it's hard to see just because it's awfully designed. not sure why corporations do things that the people never asked for when the app is FOR the people

LEGO Builder

Great app it helps me build some new ❤️❤️❤️❤️❤️

Pretty Good, but a little slow and could be better

The app is great, the purpose it serves mainly is to use the phone for instructions, and it does that well, but i wish that when you register a set to your account, it would load faster, and when you view a set, it had a link to buy it (if it’s not retired, ofc)

Wow

If I knew how much easier this app made putting together legos I would of gotten the first set I bought

Bugs

No matter what I try anytime I scan the QR code with the app it takes me to the Lego website and tells me to download the app.

Please make all sets buildable for full five stars

Dear Lego I think your app is fantastic but there is a downside. Some of the sets are buildable on the app it says start building where others you can only view instructions I would really appreciate if you made everything buildable on the app especially as some people can’t afford LEGO but this way they can still experience building the sets one last thing your LEGO polybag are not listed as well as some of your older sets please please sort this issue especially for poorly people like me who build the sets for fun until next time LEGO keep building

Use the app!

The app is way easier and better than using the manual instructions!

What happened to the app?

The app updates are terrible - I can no longer see all of my sets. And if you can’t build a set in one sitting (because life/work happens), when you go back to it the set has disappeared, and you have to search for it all over again!!! Bring back the old app!!!

Great

Great for seeing where the parts go

This app is insane

This app is perfect when it’s hard to read the instructions. This is perfect. I can do a full 3-D rendering and see other Lego sets then go buy them even show the old sets.

Very fun app

As a normal Lego builder I like the app

It helps me build

It’s really really helps me build it doesn’t follow the instructions but you get there in the end. It’s just in a different order so I don’t really care that it’s in a different order.

hate the interface layout instead of the old list view

used to like this app, it was a nice way to see all of your stats. now it's hard to see anything cleanly. i miss the list view where everything is easy to see because on a phone, you can barely even see any of the sets you own

Great Experience and Very Helpful

It’s a great app and user experience. Lots of nice features and takes the guess work out of assembly. You can tell they really care and wanted to make something both helpful and enjoyable. The interface really is fun and this feels perfect on my iPad mini

lego

Super helpful!

Nice addition to the X-Files universe!

This was a great free build to go with my X-Files set.

Easy to build, and follow instructions. The little detail is great!

As a fan though with so many monsters of the week and dead bodies… they could have provided a subject for Scully to work on, plus no voice recorder that was in every lab scene.

Other than that compact great little set as a fan.

I think I got an error

I love this app but I’m stuck at the starting screen I watched a lot of videos to fix it but it still doesn’t work?!
I don’t know what’s going on
