So, once your super secure local app will remind you to contact a friend, how will you message them to exchange detailed personal stories? Gmail? Facebook?
You give them a call to meet up sometime? idk, I feel like you're being argumentative / snide but I'm not sure if you're actually trying to make a point.
This is a particularly bizarre rebuttal. Usually the answer to this kind of thing would be "well yes but we can only solve 1 problem at a time", but in this case it's not even that. There already are ways to contact people privately!
