Essential app for power users
I use prowl for all kinds of things: notification of new emails from important people, notifications of keywords in chat rooms, notifications of events on my computers, and more. It has a dead-simple API, So its very easy to set up notifications with all kinds of custom scripts and monitors. I use it multiple times daily to send notifications to multiple devices. Its wonderful.
