I have a side project slightly similar to the functionality your tool offers focused on expense tracking (or other measures) over time, adding date parsing to the equation in order to plot metrics into a graph and with tags and locations for filtering.
I'm (slowly) working on something that can eat up PSD2 data from banks and parse it into some usable data, but I'm bad at nicely presenting stuff. It would be great to see your tool and get some inspiration, or maybe even use it.
I've been thinking of ways to parser phone screenshots with payment data or use bank APIs to add data to my expense tracker, as opposed to adding everything manually, which is the best way I've found for consistency and to make sure everything is properly formatted.
I didn't know about PSD2. Do you have any links or references for me to look at?
