About this app
PegaSystem is a light-weight, unique take on Yu-Gi-Oh! dueling calculators. With its mirrored design, one device serves both players without having to pick it up or move it! One duel = one duel calculator. Each player can only modify their own life points, streamlining and simplifying the game. After all, time shouldn't be wasted fiddling with and synchronizing multiple duel calculators! PegaSystem features: • Mirrored design means 2 players share one device! • Quick access to the Yu-Gi-Oh! Wikia, official rulings, and official Forbidden/Limited lists! • Built-in calculator to easily figure out how many life points to add or subtract. With a simple touch of a button the calculation result can be applied directly to your life points! • Quick access buttons for subtracting and adding common amounts to your life points! • Built-in dice and coin! • Undo feature (tap to undo, press and hold to clear undo history between matches)! • Player names! • Win counters! • Beautiful flat UI!

What’s New
This app has been updated by Apple to prepare for watchOS 27 compatibility. No new features are included. Finally got around to updating the UI for the iPhone X... I hope (I don't own one; too poor). Added updated art for BEWD and REBD. Subtle yet profound tweaks to the UI. Stability fixes. As always, thank you all for your support, reviews, and continued use of Duel Calculator PegaSystem! Believe in the heart of the cards!
