Friend of mine made an android app for calculating dice probabilities that works really well with pathfinder.

Check it out.

And if you don't like knowing the probability of your dice roll when playing pathfinder, then don't use the app. This is for people who like to know dice probabilities only. So there.


The probability of my rolling a 6 on 5d10 was something less than 0.01%, but that didn't stop me from doing it anyway! :-P

App has been updated to include some stats for special things within pathfinder, e.g. dogslicer d6 buff, glaive reroll, etc.


Wow, he even added the Hermit Crab. You can't do polearm versus Hermit Crab, but I consider my feature requests to be fully satisfied. Also, bigger buttons should help. Thanks to your friend!

I've found this quite helpful when deciding which weapon to keep and some complicated fights.

Here's a clickable link to the app on the Google play store: PACG Probabilities

Here's a link to the Project Page in case you want to fiddle with the source code.

Will we get the ability to roll the dice?

Short answer: probably not unless someone with UI design or programming skills wants to contribute.

Long answer is posted at Board Game Geek

I ended up adding a very simple die roll feature. I just pushed it to the play store so it should be available within a few hours.

Forced an update so that I could check it out. Thanks!

Based on my initial investigations, this doesn't seem to handle needing to discard second chance weapons or the Dogslicer.

Not sure why I see two bars on the roll dialogue.


Maybe this will help.

If you add 1d6 and set the target to 4 your probability should be 50%. If you select the "force reroll" special your probability drops to 25%. This is the odds of rolling 1d6 >= 4 twice in a row.

The simulator just attempts to beat the final probability, it doesn't do all the intermediate rolls.

The top bar shows you the roll you have to beat and the second bar shows you the actual roll. If your odds are 25% then the top bar is 75% full. If you roll under that 75% you lose.

Does it make sense?

Robert.


If I have a 92% probability of success, the top bar will be orange for the first 8% (opposite of what I would expect). The confusing part is that the bottom bar never shows any orange.

Tested on two Nexus devices with different OS versions.

The top bar shows what you have to beat. If you have a 92% chance of success then you have to beat 8% in order to succeed. The bottom bar is just a random percentage. If it's bigger that the top bar you win.

The color for top bar is just the default android progress bar. (yellow-ish orange) The bottom bar is a gradient from red (low roll) to green (high roll) with yellow-ish orange in the middle.

The UI made sense to me when I wrote it. Can you describe a UI that would be more intuitive to you? Maybe there's a universally better UI design.

Creating an interface that actually rolls dice is more work that I want to put into this for a feature I won't use.

Robert.


The problem is that the bottom bar is always completely grey. The top bar works, it is just the reverse of what I would expect. When combined with a non-working bar, it is pretty confusing; I'm sure that it makes more sense on devices where the bottom bar works.

I would be happy to contribute a simple roller, but contractual obligations prevent me from doing so without involving lawyers.


Can you post a screenshot and let me know what devices and android OS version you're using? I may be able to reproduce it on an emulator.

It works for me on a Nexus 4, 5 and 7 with Android 4.4

Robert.


Ok, I see it too. Crap. Expect a patch soon.


A fixed version should be on the Google Play store in a couple hours.

Thanks for catching this so quickly!

Robert.


That's pretty cool. I wondered why there was a time delay when rolling :)


I just got the Pathfinder ACG, and am loving this app. Thanks for putting it up here.


I should note that the rolling feature isn't useful for combat checks since you can't determine how much damage to take if you fail the check.

Great app for evaluating alternative approaches to all types of checks, however.


Thanks for pointing out that the rolls don't show damage. I added an issue to the project page.
