NAG Helper is the official companion app to Next Action Guide (NAG), the World of Warcraft addon that shows you the next best spell to press. The app runs beside the game and keeps the addon working for you: it finds your WoW installs, installs NAG into each of them, and keeps it updated automatically. Pick your rotation per class and spec, or write your own in plain sentences with the built-in editor, and it reaches the game within minutes.

The built-in simulator runs your character through a hundred fights in one click, searches for the best talents and gear for your level, and replays a fight so you can see exactly where the damage came from. The Statistics tab shows what works for the players around you: the best spec per class and fight length, the best builds per race, and a "Sim this" button on anything you want to try yourself.

An in-app coach answers questions on your PC, looks things up in NAG's guides and community notes first, and tells you where each answer came from.

No ads, no overlays, nothing drives over your game. Sign in with Discord, keep your data private by default, and subscribe only if you want the premium rotations.
