I would rather typing each letter our than pay $5 for a Lorem Ipsum Generator haha
Even a small fee generally is enough to keep the person who created it interested in maintaining it and improving it.
The time taken to type out Lorem Ipsum would be worth more than $5. I know you have other options in this case, but why would you prefer to waste your time than spend money?
In fact this app seems very sketchy, since its website is dead, and its description states "And it’s completely free!" while it's not.
