Yes, many budgeting / personal finance apps exist. Many are good, some are better than others. Mostly, though, every other small group of people have their own needs when it comes to this type of tool. Some need it to focus on budgeting, others need it to work well with investment tracking.
I began whipping up one that has more of a focus on credit cards and racking up rewards. There's not much to show yet and I'm still learning as I go. Was hoping to get some thoughts from fellow indie hackers as I continue!
This app will sort of come from ideas I implemented in this spreadsheet - https://www.indiehackers.com/product/the-game-of-chase.
What would you find useful in a new app like this? Any credit card rewards gurus out there that feel similar?
