Introduction

They see me rollin'

Dice by PCalc, is a physics-based simulation of polyhedral dice for use in tabletop role-playing games with dungeons and/or dragons.

It runs on an iPhone, iPad, Apple Watch, and Apple TV. A separate version is also available for the Mac.

Featuring near-photorealistic 3D graphics, it comes with a variety of gorgeous dice sets. Throw multiple dice with advantage or disadvantage, and any given modifier, and the app will automatically calculate the correct total.

You can save named presets to quickly roll the attack of your favorite sword, or figure out exactly how much damage your bard took from those seventeen giant rats. Flick dice to fire them across the screen when the numbers don't go your way.

Create custom dice with any text or emoji on the faces, or import your own images, and easily share your dice with friends.

Supports split screen and slide-over on the iPad, so you can put it alongside your other RPG apps, and speech synthesis that can read out the list of dice and the results.

The ideal app for every member of your party!

Purchasing for iOS / iPadOS / watchOS / tvOS

You can buy Dice by PCalc on the App Store by clicking the button below:

ios App Store

It costs $1.99 in the US, price varies in other countries. It's a (mostly) universal app - one purchase will work on iPad, iPhone, Apple Watch, and Apple TV.

It requires iOS / iPadOS / tvOS 12 or later, and watchOS 5 or later.

While it technically runs on an iPhone 5S, it definitely prefers the graphical prowess of a iPhone 6S or later. On the iPad side, an A9 processor or later is recommended. A Series 3 or, ideally, Series 4/5 watch or later is similarly recomended.

Purchasing for macOS

Dice by PCalc for the Mac is available on the Mac App Store by clicking the button below:

ios App Store

It requires macOS 11 Big Sur or later.

Currently, Apple does not allow developers to merge two existing apps together into a universal purchase, so this is a separate purchase of $1.99.
