I was under the assumption that the app would be similar to the spiral notebook with a quick reference diagram, like the notebook. The app takes more time to find a wirefill than the old-school spiral. App needs work.

I own the book already but because of water damage and time its been ripped pretty badly downloaded the app and i love it. Although i do wish they had a simulator for motors and wiring diagrams other than that this app is great!
