For those interested in receiving at no cost 'paid' apps including games, utilities, etc then there is a business called 'Instant App Review' that provides reviews for different app companies.

To do this you need to send them an email showing your interest and they will put you on the list for reviewing new and upcoming apps that have been released. The only requirement however is that

You can flick them an email at
