FreePing is a ICMP Ping Application. It is designed to have a simple and intuitive user experience.
With the help of a so called "ICMP Echo Request", you'll be able to test whether a host on the internet is alive or not. A host that is alive, responds with a "ICMP Echo Reply" and FreePing shows you the time this roundtrip took from your iPhone to the host and back.

This is a must have tool if you administer any networks!
Simple and effective

Does what is needed
