Countdown

A countdown timer? Onscreen? Easy now! I made one this evening My use case: a person does a corona test and needs to wait 15 mins to be able to take a photo so onscreen I want the countdown to appear after they have put drops onto the test cassette… and then have a button to continue once the time remaining is 0. So one column - start time Another column - the 15 min wait Next - a math column - time photo taken (start) + the time to add on (I have mins, so need to convert) …
