Every time I encounter venmo whoever has it usually apologizes for it and explains that you can turn the weird social stuff off. If that's the case, then what's the point? Moreover, it demonstrates that the people who made it have weird philosophies on things. What other choices have they made that I don't know of, can't turn off and would disagree with? Square Cash is great, btw. No bloat, very simple, does what you…
You can also change the default, although that seems to be an option I don't remember having when I first started using the app...
That is located in Settings -> Privacy... although you get a popup saying "You know you can change this per payment, you sure you want to do this" which to me feels weird and pushy.
I agree with Square Cash or other services, instead of Venmo since the whole idea of by default sharing my payments feels weird. Apple Pay works really well too if you and the recipient are both Apple users.
