I've had a Square dongle since they came out and were free, but only used it a few times. I've used Square Cash perhaps a dozen times between friends. Most people seem to have it, but its use is still fairly uncommon. Part of it is that, at my age (mid-30s), typically there's no reason to send your friends money. It's handled for payments for, say, travel expenses.. but typically if it's just a meal, we either split the check the 'old' way or someone just picks up the tab.
