In the game, and the manual, players are informed that installing the iFruit app will allow for training Chop, and give the ability to customise vehicles.
While vehicle customisation is useful, it's nothing that can't, so far as I can tell as yet, be done in-game. Training Chop, however, is supposed to increase his in-game use to the player character(s). So: in the absence of an app at this time, does a player on iOS gain an advantage over those of us using Android?

Well, people with iFruit doesn't get an advantage, but they get a few more features.
When "taking care of Chop" on the app, you can teach him tricks, which you can get Chop to perform in-game. You can also get him another collar.
So the only thing android users are missing out on are a few small features.
