I agree completely. When I'm thinking of my friends, I'm quick to contact them. But when life gets busy and I'm heads-down doing stuff for weeks at a time, anything outside my line of sight tends to get forgotten about.

Frankly, "just remember to do X" strikes me like "have you ever tried just not having cancer" in terms of useful advice. And given the number of generalized to-do apps like Reminders, OmniFocus, Todoist, etc., it seems like there's a huge market for people who need an app to remind them of stuff.
