Comments on d20 Attack Calculator for Android

★★★★★ Robby Wendel · Sep 22, 2021
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)
★★★★★ A Google User · Apr 23, 2014
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.
