Yeah, long term relationship here, we split our expenses using Google Sheets. I have to say I don't feel any pain doing it this way, and it's super simple - just sum two columns and show the outstanding difference.
I certainly appreciate how often applications can grow out of spreadsheets, but I don't see why I need an application to do this kind of thing...
Some questions that add complications, particularly when finances merge:
What are the individual budgets by activity for each person and how is the budget reflecting reality?
What about any shared bank accounts?
Do you separate investments by person? How do you handle diversification?
Those questions are not all current problems or by any means all possible problems, but hopefully you can see how a spreadsheet could grow too big for its bridges there. If Honeydue were able to provide an easy method that addresses many of those questions, it would be impressive. TBD of course, and color me a bit doubtful. I've thought of making a personalized app for myself given the level of detail I'd probably require for me to use it.
