I love this feature - I have separate vibration patterns for my wife and my girlfriend, so I can easily tell if a text is from an important person without taking it out of my pocket (and I refuse to wear a watch)
Your idea sounds cool, but then I’d have to learn Morse code which doesn’t sound fun to me
My wife’s vibration pattern for a call is SOS in morse. No side-piece for me though. Very happily married, just know if she calls it is important.
Great use of polyhaptic notifications.
Here's a fun game to learn morse code ... https://alexvscoding.itch.io/morse
I'd highly recommend even if your goal is just to have fun, and not to "learn morse code".
Great for your kids, and your other kids too!
