As I said in the same comment, anyone who takes financial transactions seriously (including, presumably, designers of a financial app) would see it as a fundamental flaw. I acknowledge that a lot of people don’t (including, presumably, the designers of this financial app), and this study backs it up.
I suppose it could be a marketing opportunity for them. “Want your financial life to be an open book? Trying to keep up with the Joneses? Use Venmo!”
Splitwise is a better option. Private and permissions-based on a granular basis by default.
