Miles & More (Lufthansa, Austrian, Swiss, and other partners) - Mileage Tracking

Does anybody here use a programm to track his miles? Is there any programm at all in germany or at least a german version? Thank you in advance for your help.

Meilensammler,

I use a simple xls. sheet and double check my xls. balance with M&Ms online balance. Its very simple but works perfectly fine for me.
