The problem is we all want to make manage our money and spending habits. But we often failed to.
This app gives you choices of different planning styles to allow you to make financial plan and create scenarios whenever you want to adjust it or purchase impulsively.
It allows prompted reflection by asking how you feel when you purchase, and how you feel now to help users understand and empathize with their own decisions.
It's unclear to me how would the app work? Is it directly connected to the bank account, or should I manually enter each transaction I make and include the "purchase feeling" as well?
I don't think people are ready to invest so much time into every transaction.
You could however make a Physical Card that you send your customers and then use that to track their spending automatically, you can use Stripe for that:

I'm interested in hearing more about the "Planning styles" you're thinking of. I think @ybouane's idea of integrating this through an actual physical (or virtual) card would be great. But for things like Amazon purchases, it won't work because on the credit card statement it just says "Amazon" so you won't be able to determine in what category that purchase is. Is it a toy, is it laundry detergent?
Nobody wants to track money "consumer behaviour"
I like this idea, people don't take the time to think about what they are purchasing and how it effects their budget.
The only problem I see is that you will have to find a way for people to actually take the time and read/ answer question because most likely people will just ignore the alert.
