Rockstar launched a free iOS app that complements Grand Theft Auto 5 today, called Grand Theft Auto: iFruit. The app offers two activities that affect the main game's campaign.

The first is Los Santos Customs, which has players creating custom cars and license plates for use in GTA 5. Chop the Dog is the other activity offered by iFruit, in which players care for the pet of one of GTA 5's main characters, Franklin. The dog, Chop, will better assist players in GTA 5 if he's well-tended in the iFruit app by finding hidden items when being taken for walks by Franklin.

In our review of the game, we considered Franklin the standout character of the playable protagonists, so we'll happily spend more time with Chop through the app.
