Yeah, so far all I see is an attempt to literalize an idiomatic metaphorical expression. Not sure how it is meant to work, nor for that matter whether the usual way of using it is meant to blow back on doctors in particular.
If the word “app” had been replaced with “pill”, it would have produced an understandable joke.
Makes sense to me (but isn’t funny)
1) Idiomatic expression is taken literally.
2) Apps are the new fangled way we do things.
In the old days of the 90s people who worked with markup languages and Standard General Markup Languages (of which HTML the HyperText Markup Language of the World Wide Web use the most famous SGML got superceded by XML eventually) we used to joke of the people who were hard core would make a Markup Language for Coffee Cups. Now a-days we say You’d use an app to chew gum if you could.
I have to admit… when I was searching for a trowel my wife misplaced in the front yard yesterday, the thought did cross my mind that my phone needed a metal detector app.
Tarzan used to have to find his own bananas, but now he has an ape for that.
@ Shrug – That’s a major groaner (not just an “Oy”, but an “Oy Veh!”).
P.S. @ Bill – The app won’t help unless the phone has a sensor. I’m not sure how the compass app works, but it seems relatively insensitive to iron, unless it’s practically in contact with it.
It took me much too long to understand that my phone does not have an ambient temperature sensor, and the little temp indicator is just relaying info from the weather service.
Kilby, it was a fleeting thought: I didn’t actually think of it as a posssibility.
Though it does seem sometimes that a phone should be able to do everything a sonic screwdriver can.
