Working on building a much simplified personal budgeting application. Been done to death, but usually not very well. What I'm making will put the simple and most straightforward aspects of budgeting front and center, and not try to boil the ocean with features. Mint is so convoluted now with all their credit and loan features that it no longer is useful for its actual purpose of budgeting.
Personally, at least among the apps I have used, no, I don't think any parts of existing apps are done well. I think there are a lot of existing applications which /do/ a lot, Mint, YNAB, EveryDollar, etc., etc. But the core budgeting/transaction aspect of them is always just the same thing, and instead of fleshing that particular aspect out, they branch out into investment management, credit building, loan/credit card recommendations. All important things, given, but the end result is a weaker product which does a lot okay but nothing great. The one exception is actual budget's (https://actualbudget.com/) reporting. Really big fan of their reporting feature, as well as their FOSS approach.
