5. iXpenseIt. Instead of monthly or annual plans, iXpenseIt's iPhone app costs a flat fee of $4.99 for the full version. Users can also try iXpenseIt Lite for free. The app can store photo receipts, but, as with doxo, users need to manually enter data from the receipt. The app's real focus is on tracking daily expenses on the go and understanding how those expenses fit into a monthly budget. With that goal in mind, the app can generate a wide variety of reports and graphs to illustrate a user's spending habits. The app also sends reminders for users to enter daily expenses.
