Could this helpful guide be any better?

Only if they keep going back in time and adding older sets! This guide not only allows you to find those pesky instructions your kids have misplaced, but organizes them by family type (City, Star Wars, DC, Marvel, etc) and by year released.

Devs: Please add a feature to favorite the current sets your kids are working on. As the family collection gets larger, digging through the sets could be helped by making a setting where the sets the kids are currently working on filter tot he top. Also PLEASE PLEASE PLEASE keep adding to this from a historical aspect. The kids have lost some of their instructions from several years ago and they are right outside where this app goes back to. I also have sets from my childhood (not going to indicate the year other than to say I had Space and City sets) and I would love to see those instructions on here. I think parents looking for these sets would be willing to pay to unlock older sets. Maybe a small one time fee would help fund adding these older sets in!

Developer Response ,

Thanks for the great feedback! 💖 If you want to keep track of your sets, just click on the little plus symbol before opening the instructions. It will add them to your profile for easy access. As for adding more sets: Our team's always working on that. 😁 Have a look on for instructions you can't find, as we have older sets there. Happy building! ✨ - Gabriela, LEGO® Customer Service



Hello, my name is Jamison, I’ve been a Lego fan for many many years. I am now currently an adult and still enjoy playing with my Legos. I stumbled upon this Lego builder app when I downloaded the PoweredUp app to play with my Lego train sets. Both apps are amazing. I showed my father on his iPhone and he was driving my trains. It was really cool. He enjoyed it very much. However, I do have one idea that would greatly improved this app. For all of us adult Lego collectors, who still own sets from the 70s 80s or 90s we would still at least like the ability to add the sets to our Lego builder profiles. For example, I have one really old set added to my list but the set does not have a thumbnail image until you click on it and then click the PDF. It’s kind of a little frustrating. So my main point here is just to add some of the Nostalgic sets to the apps inventory so that we can add them to the sets that we had when we were kids for nostalgic reasons. thank you so much. Sincerely, Jamison. aka GUARDIAN_swoop37

Modern Digital Instructions - Gamechanger

I’ve used this app in the past as an easy alternative to having some of the larger manuals within my working area when space is limited. While it was nice having the instructions available and guided as pages, it was essentially an app to display a PDF with no value add. That’s not the case anymore

The new guided experience (I’m not sure if it’s just for new sets, such as the Piranha Plant) makes building these sets easier and more accessible. Highlighting pieces to add and providing 1:1 comparisons at key build moments made this one of the fastest sets I have ever built (from an efficiency standpoint). There were never any moments where I was not sure what I was not absolutely certain where the pieces belonged within seconds of viewing the content.

This app is a fantastic enhancement / companion for those interested in building Lego and I could not recommend it more.
