ComeInHere4 app for smartwatch

Before you go into the kitchen [upstairs/the basement/wherever] etc, you announce:

"I'm going into the kitchen [wherever] to get salt [whatever]."

Then, once you are in the kitchen [upstairs/basement/wherever], you can say:

"What did I come in here for?"

And your smartwatch will reply:

You went into the kitchen[wherever] for salt[whatever].

This will save us all many steps. Its particular target market will, of course, be us aging Baby Boomers.
