From the developer:
LoLPing is a simple menu bar application that informs you about your current ping delay to the League of Legends servers. You can pick the server you are playing on from the menu, so you can learn about the lag you need for entering a game. The delay is expressed in terms of milliseconds, the time it takes for a network packet to travel from your computer to the server and back.
