I live in Denmark where we have had phonebased money transfers for years now (since around 2013 I believe). I've used splitwise for tracking purchases at a festival where whoever had money on them would buy beer or food and we would just track it in a group budget. Since you didn't have cash transactions when adding you don't need too much security so there's lower friction. Further you reduce the amounts of transactions going on, while still retaining decently detailed logs. It also gave the option of solving things with cash when splitting with people from abroad who may not have the same access to easy money transfer. Just to add some perspective. I'll check out pocketsmith - it does sound kind of cool and I'm looking at the possibility of merging my finances with my partner soon-ish.
