App to show you stats of your phone calls.
When you suddenly realize that your time is somewhere missing, this app can show you who you can attribute this missing time to :)
Also, app can create text version of call log, and you can import it to e.g. Excel, with daily updates (log is created on SD card, in DataLogs folder - so, even when your phone will be dead, you would have ability to recover this data from SD card).
