Ratings and reviews

This app is your personal cheat code. Doing my 1st Technic build and was impressed by the manual but when I downloaded the app I was shocked at how well it was done. It's basically a mini CAD program on your phone. And then add in the audio and video notifications when I stage is completed is a nice touch. I also like the fact that it shows you what sub-assembly you are about to build and where it's going to go before it breaks it down into the individual components. Can't rate it any higher

really great App, no in app purchases, no ads, easy to use, gives you 3D instructions that you can turn any direction to get a better view of where each piece goes, makes registration of your sets for rewards program easy, and helps you organize your sets and keep track of which ones you have. you can close the App in the middle of building a set and when you open the app to continue building it, it will start you right where you left of without having to start again from the beginning

I love this app! Extremely helpful in building your sets. You never lose your place where you end your build. If you think you forgot to connect a piece, you can always go back to the previous page and so much more. The app is super easy to use with the zoom in, zoom out, 360° turn and rotate!
