Delta Touch, formerly known as D-Touch and Doom Touch, is an application for Android OS by Beloko/Open Touch Gaming. It combines GZDoom, LZDoom, Zandronum, Chocolate Doom, Doom Retro and PrBoom+ in one streamlined app. Delta Touch offers a highly customizable and intuitive touch screen interface and supports most, if not all, Bluetooth-enabled wireless controllers, along with mouse and keyboard functionality (Oreo 8.0+). It also includes downloads for Freedoom Phases I and II on its game selection menu, to allow its users to have a game to play without needing to supply their own WADs.
The engines support all IWADs, though some PWADs and PK3s are not supported on all engines. The GZDoom, LZDoom, Zandronum and PrBoom+ engines offer both software and OpenGL ES accelerated rendering. Zandronum's multiplayer server browser is found under the in-game options menu. Bots are available for offline gameplay.
