Best App for Building Instructions! ⭐️⭐️⭐️⭐️⭐️

I absolutely love this app! I’ve only had it for a day and a love it! One suggestion, do you think with he 3D instructions that you could show us how long an axle is, like in the printed manuals? Thanks!

It’s an alright app

The app looks great, I'm not going to lie but it has it’s problems.

What it does right:
•Letting you see most available sets from now and the past years.
• Having a collection tab where you can add the sets you own to have backup instructions at all times.
• 3d model instructions on some sets.
• The 3d models look great and are easy to use and build with.

What it does wrong:
•The 2d instructions are really dark and hard to follow.
•Some sets from recent years are missing, and can’t be found by using the search bar (one set I was most disappointed about was set 9525 Pre Vizla’s Mandalorian Fighter).
•Not all sets have 3d instructions.
•Almost all of the older sets up to 2012 are missing

This app is good but not great especially that most people would have their instructions for newer sets and the older sets need online instructions more. I want to see this app succeed.
