I don't think one goes against the other. Meeting in personne would never be replaced by an app, but with work, kids, distance, it can be really easy to loose touch.
This app also focus on questions that you may not have even thought asking your friends or even yourself.
I use a simple question to determine whether I've "lost touch" with someone or not: do I have a regular or semi-regular urge to talk to that person?
I find the answer is often no. Lots of folks gain and lose friends unexpectedly over time. It's ok! It's natural. It feels (to me) unnatural to feel unhappy about not communicating regularly with a friend: that person is just not as close of a friend anymore.
