I think this was my first Technic build. Somehow, when looking for the instructions (I prefer to use the online version), I came across the LEGO Builder. It took me a minute to get used to how it works. Now I'm going to see if it's available for my other builds. I hope so, it's such fun! Beware, the sound effect when you complete a section can be very loud! Made me jump several times in the beginning. I also like the accuracy of the colors of the parts. Thanks, LEGO, for this excellent app.

Really cool app, hoping it replaces the need for publishing books for kits. When I did the Star Wars font lettering kit, the app was awesome for that because everything was movable, pinch-able, zoomable and 3-D however when I went to build the Land Rover Defender, the app was basically a scan of all the pages that came with the set which got really blurry at times when I pinched to zoom on the app. Having said that, I am using a Pixel fold 9 and apps can tend to be funny like that on this device

Very annoying that it is optimized for mobile and won't resize well on my tablet computer. The search feature is also not great, even when I type in the collection name, it's just easier to type the set # once I find it, because otherwise hundreds of irrelevant sets pop up, even if I search with quotations. But its the only way I can get my retired set instructions.
