A companion app for GTA V, where you can play with your dog, Chop from the game and customize your cars. It is useful at first, because you can create a custom license plate for your cars and also unlock new tricks for Chop by earning money to use for training and keeping him happy by buying food, drinks and going for walks to complete mini-games. You can even by different colored collars and stuff. After buying everything though and trying out the new tricks it just becomes annoying, because you can't use your tricks in GTA V unless you keep caring about your phone dog, which is just bad design in my opinion. Unlocked tricks should be accessible at all times.
