Apps are fun or useful applications built by third-party developers for Yahoo!, such as the Weather App that appears on the default Yahoo! My Telecom page. You can personalize your Yahoo! My Telecom page by adding many different apps. Other examples of apps are games, a calorie counter, and a money management tool such as Personal Finance Manager.
