I have been using Mileage Manager for the past year. I find it to be a very convenient and inexpensive way to manage my airline, hotel, credit card and car rental miles in 1 place. It is very simple to use. You simply add the user name and password for each frequent flyer program you belong to. It then gives you a summary of all your frequent flyer programs as well as the points needed to get to the next status level. They also alert you of mileage bonuses.
