Guide for GTA 5 is quite a comprehensive guide for Grand Theft Auto V with tips for solving difficult missions. The application is pretty simple: it shows the name of the missions and a short text with instructions to complete them. The app also has a series of interesting tips, as well as codes for tricks.
An interesting element in this Guide for GTA 5 is that it offers custom codes for the PlayStation 4 and Xbox One versions of the game. In other words, it doesn't matter which console you're playing on, the guide still shows you which codes are good for yours.
Guide for GTA 5 is a somewhat mediocre guide with quite an ugly interface, but at least it helps you beat Grand Theft Auto 5, which is what it aims to do anyway.
