I made a simple app for budgeting (fun note - my wife still has it on her phone). It allowed me to categorize everything and set specific parameters around how money was flowing in and out of my accounts. It helped with budgeting and projecting my future net worth.
I liked it a lot! But since then I've used YNAB, and now Monarchy, and find them better tools that fit the bill. Nudge got me moving in the right direction, and Monarchy has the staying power of a great budget tool.
Goodbye Nudge, it was nice knowing you!
