About

TinnerFlow is built by a commercial sheet metal worker for apprentices who are standing in front of a problem right now, with a foreman about to walk by.

It answers one question: what lane am I in, and what do I say? It is not a training platform and it is not a code book. It will not tell you a gauge, a spacing, or a clearance for rated work, because the only correct answer to those is the approved detail on your job.
