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.

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.

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.

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.
