Very good

This is one of the best ones out there. My only request would be to add a feature that allows the number after the modifier (plus, minus, or whatever) to be added only once, and not to each dice. For example, when you write 2d6+5, many RPGs assume that means a numerical range of 7-17, but with this roller its actually a range of 12-22 because the +5 is being added to each die. If there were a way to toggle or change so that the post-modifier number was only added once no matter how many dice were rolled, this would be hands-down the best, most powerful roller available and Id easily pay 10+ dollars for it.

UPDATE: Nevermind, I found out the app DOES have this feature! You just need to put spaces before and after the modifier. Thus, 2d6+5 is roll two six sided dice and add five to each, while 2d6 + 5 is roll two six sided dice and add five to the total. This could be stated more clearly in the help section, but thats my only complaint. Amazing app all around.
