Why would you spend $3 for an app that is just a Disneyfied version of most free budgeting apps? I'd rather save the money and live without the oixie dust.
Now, if Disney came out with an app that tracks your spend automatically, then that would be worth taking a look at. I could get on board with having an app that shows me what I've spend without me having to manually enter every little transaction. But an app that requires me to enter everything myself is just one step up from a calculator and not worth paying for.
