I love all the comments that I'm reading here, but for most of the cases that are being presented, I'm having a hard time imagining myself needing to do the same, because for the most part there is always an app that already covers that need.
For example, your use case sounds like the ideal scenario for Settle Up. Me and my 2 closest friends have a running group where we annotate expenses and there's always a clear picture of who owes what amount and for what reasons.
Of course, tiny customizations like a dog's picture per month, are not possible to do with a 3rd party app :-)
It wasnt more about solving a $ issue as to morphing their interpersonal behavior over a tab between sisters... (and my personal friction) ((have you met any sisters who are both close and highly successful in different fields)) - sometimes, you just need to leave the room... this was my method of exiting the room of financial "settle up" types of comments - and I had the mortar of dog pics.

That’s till some product manager decides they want metrics to go up, and the app starts spamming you notifications multiple times a day, or tries to shove in your face unnecessary financial products, and starts selling your transaction data with the hope of increasing monetization to keep their overstaffed teams…
A home-cooked app from someone you know/trust seems much nicer than that.
