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

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. Also comes with a companion Apple Watch app, so you'll never be without a D20 again. Even supports AR!

The ideal app for every member of your party!

Beautiful dice roller!

Lovely way to roll the dice. Nice having different dice colours available. Fun to find the bananas too!

Needs options for other games

Lovely looking application but as I can tell very focused on D&D type games.

It would be nice to have an option for games like Warhammer where you roll nD6 and can see/filter all rolls that are over a certain score.

A mixed bag. Beautiful dice, frustrating UI.

This app hides beautiful dice, physics, and lighting behind a tricky user interface. If you're rolling one dice at a time, get this app. If you're rolling multiple dice, I think there are better apps that deliver much better on the execution.

The lighting is really beautifully rendered, the skins for the dice are lovely (check out the detailing on carbon fibre, the texturing is beautiful) and it's great to have such fine control over so many aspects of the app.

But I find the app frustrating to actually use. I really don't like having the controls up the side in portrait orientation. It takes up too much space.

Rolling multiple dice at once is a common operation and I find doing so in this app frustrating and something competing dice apps execute better on. I dislike how there isn't an option to auto-remove die when you roll a new die/dice, so dice just pile up.

I really like having a lot of options for dice, their environment, and lighting, but again the UI really gets in the way. When I'm changing the dice, the environment, etc, I want to be able to see the dice, to see all the detail. Instead, I'm stuck in a menu and have to tap out to see the changes.

I don't enjoy the camera angles when rolling multiple dice—I never have a great shot of all the dice. Controlling the camera feels unresponsive on my iPhone Xs and I couldn't find a good way to tilt the lens how I wanted to tilt it.

I could go on. Particularly about the menus.

As you can see, I have a lot of complaints. But the actual rendering of the dice really is fantastic.
