The article didn't specify what role she had in the creation of the app, so I will assume that she designed the interaction model (at least loosely) and worked with someone else to actually build it.
Anyway, if my slightly pessimistic/cynical view is correct: that's still nothing to sniff at. My lovely and relatively tech-eager 73 year-old mom hasn't gotten to the app-producer role yet. :)
