I hope everyone has some great suggestions here. I read a few articles on ‘best interactive widgets’ that all seemed to be for apps I don’t use and/or would not consider because of permissions. I thought Apple would be all over this with their own apps, but not as yet it seems.
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. :-)
