<prompt> Human: Wife and I use YNAB at home and keep it updated weekly. Most of our spending goes through our credit cards and is easily tracked. Im looking for a fast iOS app to keep track of cash expenses. I dont necessarily want to install YNAB on both our phones. Any recommendations?Edit: Thanks for the suggestions, will try YNAB app after all.  <response>: Mint has an ISO app look into that its free.
