We bought a new barbecue grill over the weekend. It came with a 30 page instruction manual. The paper manual also mentioned that the instruction were available on a mobile application called BILT. I decided to test it out and it is awesome. It shows each step, the parts you will need, and what you need to do (and sometimes it even tells you what you need to do). It also lets you rotate the image and zoom in or out.
For example, here is one screenshot from the instruction guide. It will tell you the parts that you need (in the upper left corner), it shows you what you need to do (in this case, insert slats and install screws in orange).
It made building the grill much easier. This application is a huge improvement over the paper instruction guide.
