I’m a single-pager when it comes to home screens, so screen real estate is exclusive for me.
I found one interactive widget worth putting into a 2x2 stack: CardPointers. I can quickly update and review the best credit card to use at wherever I am, from my Home Screen. Nice.
If I wasn’t such a stickler on keeping a single Home Screen, I’d probably use a larger Reminders widget. (I like checking stuff off lists. :-)
I can’t find my source for this memory, but I recall several years ago reading about Apple introducing automatic device resprings / restarts overnight. I think I still had my iPhone X at the time.
In my experience, it only happens while charging. I might have to cruise the old jailbreak subreddits to find whatever I think I’m remembering here.
