What do iPhone user reviews have to do with the Mac community?
Get your iPhone.
Go to the App Store.
Search "a phone tracker spy"
Read the first 100 reviews.
yes they can be. There are far too many people who leave crappy reviews for developers because they can't read. They can't see that a certain OS is required, or a certain phone - or that the app only does x, y, or z or that a feature is COMING and is not yet on the app.
A lot (and I do mean a lot) of negative reviews I've see are what I call - operator error.
