Pricing apps as non-digital goods is hopeless in the long run. If you’ve read the Internet at all, you’ve seen what I call “the latte rationalization,” which goes something like this:
If you spend $5 a day on coffee, why can’t you spend $5 one time on an app that benefits you every day?
The problem with “the latte rationalization” is that there isn’t another shop down the street that’s giving away cups of coffee for free. But, in the software market, you can find dozens of competing apps that will work well enough. And many of them are available at no cost.
