Here's a run through a turn of combat in Helm's Slain using the GM companion. Note that the players roll their own dice, the GM companion takes care of that for the monsters.

Hits and misses appearing for the party and monsters

Our party faces off against a group of dark elves. After some combat you can see the hits and misses starting to appear for the party and the monsters.

Quick pics from one of our Helm's Slain sessions play testing the companion app for both the GM and players.

The player's companion auto calculates just about everything, keeps a list of spells handy and lets you focus on enjoying the game rather than record keeping.

When running the app on an iPhone, you'll have access to the player companion for tracking your character details.
