Yes, this is a weird one, and I wonder if its contextual. This question to my kids is designed to allow them to observe the world. So many times we go through a day and miss the world around us.
My favorite one in the morning is the sound of birds. On the iPhone, there’s the “Bedtime” timer. It’s between the alarm and stopwatch. For the wake up sound, choose the “Birdsong” It’s a great way to start the morning.
