Apple has allegedly changed its policy regarding iPhone apps carrying 17+ ratings, now allowing developers to issue promo codes to reviewers, according to SlashGear. The company previously had restricted use of promo codes to apps with lower age ratings.

The restrictions sparked criticism from a number of developers, as the criteria for a 17+ designation recently expanded to include a number of apps that are not outwardly offensive. Along with apps that include foul language, excessive violence or mature themes, the 17+ tag is also placed on any title that allows access to the Internet.

Many developers feel Apple has been unclear about terms for the App Store, while selectively choosing to enforce certain rules and ignore others. The company this week rejected an app that pretends to detect a user's sexuality, iGaydar, for "objectionable content." The app simply provides a random percentage and tongue-in-cheek statements.

Meanwhile, the reviewers approved Bruno, an app that allows users to undress Sacha Baron Cohen's character and touch various body parts to hear statements that could be considered offensive. iGaydar's developer suggests Bruno's studio backing and publicity are primary reasons for Apple's double standard.

The 17+ ratings for Internet access also appear to be placed inconsistently. The full-featured Journey browser carries a 4+ rating, while another browser app, Oceanus, is rated 17+ for frequent/intense violence, sexual content or nudity, drug use or references, profanity, simulated gambling "Horror/Fear" themes, realistic violence and mature/suggestive themes. Both titles, however, could be used to access the same objectionable content.

Under Apple's previous rules, the Journey developer would have been able to provide reviewers with promo codes as part of its marketing campaign. Oceanus, however, would have required the reviewer to pay for the app unless the developer provided direct monetary reimbursement.

Apple has not yet acknowledged changes to its 17+ promo code policy. It remains unclear if the company has reversed the rules for all developers, or simply allowed exceptions in particular cases.
