Ping+ (ICMP Ping Tool)

Use this app to send ICMP "Ping" packets with full control over payload size, TTL, timeout and ping speed. Based on a low level highly sensitive ICMP library, this app delivers the most accurate ping results on the App Store.

Customizable settings for:
• Payload size
• TTL
• Timeout
• Ping frequency

Key Features:
• Packet Loss
• Jitter
• Standard deviation
• Average RTT
• Minimum RTT
• Maximum RTT
• Intuitive and extremely easy to use user interface
• DNS lookup (so you can ping hostnames as well as IP addresses)

Unlike most other Ping apps in the app store, this app is not based on the Apple SimplePing sample code. This is built using a custom low level Ping library that gives extremely accurate round-trip timing results without being impacted by UI and other processing on the main thread. This is not the case with other apps as the normal SimplePing module is built as a single threaded class interleaved within the main thread of execution and as such suffers from all kinds of indeterministic errors. Our library is a multi-threaded class built on top of BSD sockets and GCD, delivering the best possible timing accuracy regardless of system state or device power.
