Pingbar is a small menu bar app, that constantly checks your connection to a server (and port).
- Let it check your internet connection in a public WiFi hotspot, like your favorite coffee shop. Visiting a bunch of links, that are apparently all dead and it's actually just the WiFi? Know immediately when your connection has a problem.
- Use it as a server/service monitor. Check if a certain service on your server is responding, like your webserver, mailserver or any other service that responds on a TCP port. Get instantaneous notifications on your desktop, when something's wrong on that port!
