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!

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

Looks pretty good BUT…

Just downloaded the other day and look forward to trying on my iPad as my phone makes it too small to see the building instructions, even zoomed in it’s difficult. The one thing that I noticed so far that I would add/change is a wishlist. I wish my list would transfer from the site to the app and then you could just move it to bought after you acquire it! But so far so good!

Edit: I removed one star because I pulled up one of my sets on the app because I took it apart to clean it and went to put it back together and within the first few pages I ran into one of those pesky weird colored pieces that I can’t quite figure out. I thought 💭- Well this is a perfect time for the app! I hope they have the piece identification numbers in the digital build instructions. That would be extremely helpful… Nope 👎🏻 They sure don’t. Instructions look exactly the same as the book. Lego needs to either do a better job at making the instructions more clear for those weird colors or better yet Lego could realize that some people are even color blind to some pieces and help with a way to make them distinguishable. I’m NOT color blind and have so many problems with certain pieces.

I’m about to take the time while I’m rebuilding my sets after cleaning them to add certain part numbers myself into my books. 🤷🏻‍♀️

Cool, but

I got this app because I am missing a couple instruction manuals for my Lego sets, but I noticed that you don’t have some of the older Disney princess or Lego friends sets. Such as raves castle with her three brothers or Rapunzel‘s tower the one with the older style molds and stuff I don’t remember the name for the redheaded girl of Lego friends but her old lemonade stand is missing. Also the Lego friends Olivia set with that rescue she had the Chamaeleon in that little tiger is like a rafting rescue or something also the Lego friends Olivia set with that rescue she had the Chamaeleon and that little tiger is like a rafting rescue or something. Then there was Stephanie‘s car from the original Lego friends and Stephanie‘s airplane seaplane I think it was. I would really love to have the instructions for those because my books are all broken and old. But otherwise this app is great because I can put the Instructions on my phone.
