An "App" for everything? (Zipper Fail)

 

Not yet dear friends.

A few days ago I had an appointment with my good Dentist at 3:30 p.m.

I set off in what I thought was adequate time;  forgetting that I'd be challenged by the "School Run": -  High School students with their own cars; school buses; and parent drivers.

I arrived with a minute to spare.  Ne'er mind; I had time enough to use the men's toilet.

'Twas then that I discovered that my fly front zipper was down.

This was not the first time.  Indeed I have forgotten to zip up eight or more times in recent weeks.

I need an App. which calls out "zipper, zipper, zipper" as I leave my home.
