If you are looking for a way to keep track of your spending, I recommend the Spendstack app for iOS. You can organize by categories either thru tags or folders. You can add sales tax to individual items. You can set items to one-time or reoccurring on a yearly,monthly,weekly or daily basis. For groceries you can also input weight amounts. Once you set your payments up you can see how much you are spending weekly, monthly or yearly for various categories. I have found it incredibly helpful in determining where I am overspending.
