FreeCost interprets the log files made by internet dialler programs (like FreeDial), and tells you how much the phone calls are going to cost you.
FreeCost comes with full instructions in its !Help file, you can download it from this site. This is version 0.43d, dated 22 June 1999.
FreeCost needs Acorn's ToolBox modules. If you do not have these modules (they are in the RISC OS 3.6 and later ROMs) you can download them too.
At the moment, FreeCost fully supports the FreeDial and SlipDial programs, and also, as far as I am aware, the ANT Internet Suite.
FreeCost is fully RISC OS 4 compatible.
