Description
d20 Attack Calculator is a powerful combat calculator, optimization tool, and dice roller for d20 RPG systems such as Pathfinder RPG or D&D 3.0 / 3.5 / 5th Edition. Use this program to roll dice for your complex attack routines and evaluate your character build from visual graphs and dice roll statistics.
Features: * Attack calculator and dice roller / calculator * Plot key statistics for your dice rolls: - Expected (average) damages - Hit chances - Dice roll distribution and averages * Analyze your DPR (damage-per-round) and appropriate challenge rating * History data for your d20 attack rolls
The DPR analysis can be used to tell you how long it takes you to solo a monster of a given CR (or AC), on average, providing players a rough measuring tool to estimate their power level.
See more information on how the DPR calculations are done and a tutorial on "how to determine when to use Power Attack" at: http://www.hapero.fi/d20/
If you would like to test the program, check out the free Lite version. This full version includes all the features of the Lite version an in addition:
* Unlimited saving and loading of attack routines and plotted graphs * Hit chance graphs for attacks * Multiple buffs/debuffs to attacks * Export plotted data to other programs * More statistics and graph data from your past d20 rolls
What's New?
Ver. 1.9: Improved dice roller: compute powers, multiplications, divisions, and roll High/Low rolls. E.g.: 4d6H3 - roll 4d6 and keep the 3 highest dice. 2d20L - roll 2d20 and keep the lower dice.
Ver. 1.8: Support for 5th Edition rules and Advantage/Disadvantage buffs. Roll distributions can now be evaluated in the Stats dialog to get the chance of scoring more/less than a given dice roll. Customization: "Use Target AC" option can now be disabled from the Settings. Added an option to show chances for "all attacks miss" curve. Minor bug fixes. I'm still quite new to the 5th ed. rules, so all feedback is very welcome!
Ver. 1.7: Added a generic dice roller, which can also show stats such as averages and result distribution for the roll. Minor bug fixes.
Ver. 1.6: Added Quick Buffs to attacks for faster bonus controlling. The history of the past d20 rolls can now be monitored from the Data and Settings page.
Recent changes: Updated to support Android 13. Minor bug fixes.

Excellent app. Many options and incredibly useful for planning builds. Would be nice to see triple advantage as an option, but only Elves with the correct feat have this option so not too common.
★★★★☆Chris Depot· Jan 18, 2017
Extremely useful, a bit tiring on ones fingers (retyping the same things a lot) I love the app, but a few suggestions that would earn a 5star: 1) Shared data folders. I bought the full version to export, only to find they weren't shared. I had to reenter my numbers. 2) I often use the different attacks as different weapons, by enabling only one attack at a time when using plot to graph. Being able to rename each attack would be extremely nice. (Ie: Rapier instead of Attack1, and automatically showing up as Rapier when I use plot to graph, without having to rename it there every time)

Incredibly useful app Wonderful app for handling all the attacks of a 2 weapon fighter. Lots of flexibility for adjusting the attacks and damage per swing. Would love the option to save different attack sets for simpler access!
★☆☆☆☆Matthew McKee· Apr 20, 2015
Great App, but unusable without overflow menu I love the functionality of the application, but without the addition of an overflow menu, you can't access many of the features on devices without a physical menu key. If that was fixed, it would be 4 or 5 stars.
