In the (software/web) start-up culture, technical means writing code. If someone says "I'm creating a fitness app, yeah I'm technical" you expect them to mean "I can code" rather than "I know how to use CAD". Your argument applies in many contexts, but not this one.

Yup, I kind of acknowledged that already, what you say is true of course. Yet in my environment I can still imagine software scenarios where I can say "you need a technical guy for this" to my friends and mean a non-programmer or a special type of programmer. I say no harm in being precise if it costs nothing.

In the case of a fitness app, I could easily imagine it meaning 'my background is in human physiology and nutrition'.
