PocketZot — Dungeon Crawl Stone Soup in your pocket, on iOS and Android

PocketZot is an unofficial, mobile-first WebTiles client for Dungeon Crawl Stone Soup (DCSS). It connects to standard DCSS WebTiles servers with an ASCII-first, touch-friendly interface.

It is also a WebTiles server: a full build of DCSS runs on the device itself, so you can play with no network at all. There is no DCSS app on the iOS App Store. PocketZot lets you play DCSS on an iPhone or Android phone: it runs in the browser (Safari on iOS, Chrome on Android) and installs to your home screen as a Progressive Web App. JavaScript is required to play.
