A real-world iPhone app has been created which allows players to control the in-game phone in GTA V, using your own iPhone!
It looks impressive and it’s a pretty neat technical achievement, if nothing else. There’s fairly minimal lag too which is all the more admirable. Inputs on the iPhone send a URL to an Arduino webserver, which then sends the inputs into the game via keybinding macros. It’s just how it works and I couldn’t possibly wrap my head around it.
Check it out for yourself now!
