If the app is inaccessible, why did you put it in here?

Hi, I added the app to the directory so that other people would know it doesn't work and not to waste their money on it. I thought that was the whole point of having the AppleVIS sight--to provide information about both accessible--and inaccessible--apps?

The purpose of the App Directory is to gather information on both accessible and inaccessible apps, as it can be just as valuable to know that an app is inaccessible (particularly when it is a paid app, like this one.

One other potential benefit of posting inaccessible apps to this site is that developers might notice the negative comments and do something to correct the problems (I suspect many developers regularly search on Google to see what people are saying about their apps).
