Quantum gives you the best way to track your life points and counters for Yugioh duels.

Our features include:

• Change LP using gestures (panning or tapping)
• Multiple counters support.
• Dark mode.
• Match history and sharing.
• Roll virtual dice.
• Coin toss.
• Up to 6 players!
• Battery-friendly.
• Sleek design.

We're passionate about Yugioh! That's why we built the best Yugioh life points counter app, where every feature revolves around minimalist design and ease of use. 

This companion app follows a different approach as compared to a normal Yugioh calculator: instead of typing damage dealt or gained, you simply swipe your finger up or down (with options to toggle it left or right). To provide additional speed or precision, you can modify the increments of each tap or pan (by 1, 10, 100 or 500).

Need a die or coin? Don't worry, you can always roll dice or flip coins with wonderful animations.

Quantum provides a dark mode which helps you save battery life, so you will consume as little energy as possible. A simple long press offers a quick access to multiple counters and other options like doubling or halving your LP.

This LP calculator app is highly customizable, you can change colors and starting life totals. Toggle player tags, edit player names and use random pickers. Do you want to track Yugioh LP & counters just for yourself? We included a single player mode, where all the available screen space is just for you.

We love feedback. Our goal is to bring you the best, ad-free Yugioh Life Points Counter app, so don't hesitate to contact us if you have any suggestions!

I am thoroughly impressed with this App I tried anything I could to break it in the last 10 mins and no problems it’s light and fast. I like the simple design 10/10 I can press 2x as much as I want and that makes me happy.

Easier to use

Just found it and hope to use it but don’t know what the customization does or potential settings

Developer Response ,

Thanks for contacting me! The customization menu allows you to change the player's colors and names (instead of showing P1, P2, etc). The history menu keeps track of all the movements of the current match, with an option to export the data to a spreadsheet. Dark mode allows you to save battery life and prevent eye strain by using mono chromatic and dark colors.

I hope this clarifies your concern, but if you have any other questions feel free to contact me at
