Prowler is a simple OS X widget interface lets you send messages to any iPhone or iPod Touch running Prowl, delivered immediately using push notifications. A fast and easy solution for posting URLs to your hand held, or any other info or notices you might want to push.
Enter your API key (readily available from prowl.weks.net after logging in) and you're ready to go! Sending a push notification requires title and/or message, along with a selectable urgency level. Any included links will automatically show up as clickable on your device.
