Do you ever lose track of dice math during a game? You are not alone. That is exactly why I built RollHelper. It is a clean, easy-to-use app designed for tabletop RPG players. With RollHelper, you can roll a wide range of dice types, apply modifiers, and review your roll history with ease. The app calculates everything instantly so you can stay focused on the game instead of the numbers. RollHelper is now live on Google Play.
