The apps great for looking at sets, and examining them close up, but you can not build with the app like it promised.

Needs a builder

I got this app in hopes of

1. Building a K’nex creation

2.having a physics engine fo test it .

Not as good as I hopes. I’d love if they added a building editor

Needs More Models!

This is a great app that works as advertised. I'm an electrical engineer and this app is somewhat reminiscent of the CAD tools my mechanical engineer coworkers use. If a model is available in this app, you can explore full, very detailed, 3D models of each design from all possible viewpoints and see how it's constructed. Not much use, but it's great for when you feel you've exhausted the instruction set of your current K'Nex set and want to build more without having to actually buy more sets or download a ton of lengthy PDFs. I only wish they had more models included, since what's currently available in the app is hardly the comprehensive library of K'Nex products, especially the huge 600+ piece structures.

If this app were to get really ambitious, they'd let users create their own models in the app and share it on a cloud server or other social media platforms.
