Rechnungs Checker 1.0

Deutsche Beschreibung weiter unten.
English
Analyses itemized phone bills by assigning each call to a person and giving sub-totals for each person. It is useful for splitting up a shared phone bill, say in student flats or families. It can also be (ab)used for analysing the total cost of internet access, calls to certain numbers etc.
In its current incarnation the application can read data files as generated by Skype Out, Deutsche Telekom, the German branch of O2, NetCologne, Arcor and British Telecom. However, in case you think a version that is able to read different file formats and that is localised to other languages may be of use, let us know and offer some help.
You can teach Rechnungs Checker which numbers are called by whom and enter the basic fee as well as the tax rate. Rechnungs Checker will then do its best to split up your phone bill. The result of this can then be printed or sent to the different persons directly as an e-mail.
