Pinger is a simple networking tool that allows you to ping multiple addresses simultaneously.You can enter an IP address or site name and hit start. It will then ping the targets continuously all the while displaying the milliseconds needed to complete the trip. Pinger has no features to speak of other than the ability to add sites that you wish to ping often to the in-app address book, your machine and address are added by default. The UI is completely uncluttered and once you start pinging it just chugs along providing up-to-date info - simple.
