Third-party applications supplement players' "Eve Online" experience. Some of these, such as automated applications designed to claim publicly available contracts accidentally put up without an associated cost, can result in a ban if discovered, while others are endorsed, tacitly or explicitly, by CCP. EVEMon, a .NET application that monitors and forecasts skill training times, is one example of an explicitly authorized external application. Another such application, Eve Fitting Tool or EFT, allows players to try different ship setups and see how certain skills and modules will affect that ship.
