I am terrible with time.
I promise the kids I’ll be back inside in 10 minutes and 30 minutes goes by. Time just passes at a different speed when you are engrossed in something.
There are apps to solve this problem. They go on your phone and I even installed one. My phone went flat. It just chewed up the battery at a great rate of knots finding out if the time was up yet.
Okay, I’m in a phase of doing apps myself and I haven’t had one up for a few days so here is a possible solution (see picture).
You can run it here.
I don’t know if it is any better on phone batteries as yet.
