I’ve only tried one other hangman app (Hangman by JamSoft) and MobilityWare’s Free Hangman is definitely superior in just about every way.
In single-player mode you get to choose from a bunch of themed word lists, one of which is Halloween of course, and in two-player mode one of the “players” can type in their own word for the other player to guess.
In keeping with the wildly popular Halloween theme of publicly executing people who look different from you, Free Hangman’s victim is a spooky little pumpkin-headed scarecrow guy who is accompanied by a buff Chippendale dancer wearing an executioner’s hood.
If the hanging Mr. Pumpkinhead creeps you out, there’s an option to change him to an innocuous stick figure. The Chippendale executioner stays, though.
When you’ve solved your word, you even get to see the definition by tapping a big blue question mark icon which opens an in-app Dictionary.com query to display the word’s meaning. Cool! Kudos to MobilityWare for thinking of everything.
Free Hangman is ad-supported but that shouldn’t scare you away from installing it. If ads bug you, just pay $.99 for the ad-free version. MobilityWare also makes a ton of other apps, most of which are either free or cost just $.99.
