Perfect D&D dice calculator

I use this all the time for D&D, especially for large dice rolls.

Best digital dice app

It just is. Check out the app its free!

Needs update for Split View

This app is really great and convenient. But it’d be even more convenient if it supported Split View.

Wonderful

Great little app, does exactly what it advertises and does it well

Best app in the ttrpg toolbox

This is dice roller app is the easiest to use and the best I’ve seen on the App Store. A must have for GMs and players.

frustratingly close to perfect

Presenting die rolling as a calculator is a great way to do it. I just wish it worked more like a calculator, where you could continue the calculation after pressing =.

Like, if you rolled d20+7, then remembered your check should have a -2 penalty, there should be a way to subtract two without rerolling the d20.

Cool

I like how it shows the Maximum number. Helps with crits

Wish It Would Sum (Easily)

It’s reasonably random—more rare than you’d think—and it can roll any combination I’ve run across in a game.

I do wish it could sum the individual rolls—keep a running total, if you will.

Also, a better display would be a major benefit, so I can see the series of rolls, not just the one just made—this goes along with my first “wish”.

There are several other dice bags that do summing and “show the tape”, but their randomness is nothing like as good as Lion’s Den.

Awesome app

Very easy to use great for rolling attacks with your bonus to hit and damage in 5e D&D.

Balanced for when your dice arent

I use this roller whenever i dont have dice on me or when a die i havent tested yet seems a bit off. It works great and id highly recommend it to those who need a die roller.

A must

Easy to use and preload frequent damage rolls.

Simple and capable

Straightforward and does everything I want. Intuitive interface and deep feature set. An essential for any DM.

Simply the best

I do a lot of dice rolling and I’ve looked at a lot of apps. I settled on this one years ago for its simplicity, power and elegance. Look no further if that is your goal.

The best

Honestly the best dice roller and calculator for gaming that I’ve ever used

Solid, but no Slide-over on iPad

This dice app is solid, fast, and doesn't have unnecessary features.

It does, however, require the full screen on an iPad and cannot be used in slide-over mode. Fine if you want to run it on a phone to the side, but it would be nice to have access to the smaller interface for quick rolls.

My Go-To TTRPG Dice tool

d20 Calc had been my go-to app for all my tabletop RPG needs for years now. I don’t need a pretty looking dice calculator, just one that works. This gives me everything I need.

My go-to

DM here. This has been my dice roller for years for anytime I need to roll irl and don’t have my dice handy, as well as big dice pools. Simple calculator format, you enter your dice formula and boom, fast result and you see the individual dice results. If you already think in dice formulas, this is for you. Also works as a simple calculator in a pinch

Absolute Gold

Such a sleek, simple little app, the UI feels clean and natural and the layout is great. This plus Complete Reference and the built-in Notes app makes my phone a literal portable DND Session. I most definitely recommend this to any aspiring DND player or DM.

The best

I've tried a number of dice-rolling apps, and this is easily the best one.

Power?!

Honestly really good I have a paladin that does a insane tone of dmg per turn so that helps me out cause I don’t have that much dice thanks a lot
