Mexer is a web-based real-time price and volume aggrigator for Bitmex. It shares some of the same qualities as Bitcoin Battlefield, but is minimalistic and Bitmex-centric in nature. It works great on mobile and desktop.
A poorly named windows desktop application for Bitmex. Manage, place (bulk) and ladder orders with ease via the API. It also supports multiple accounts as well as the Testnet.
