Telluric

"Telluric is a powerful, flexible, and convenient portable packet capture analyzer.

Whether you’re having a night on the town and just experienced a major network outage or you're a researcher who’d prefer to explore from the comforts of your couch, Telluric is the right tool for the job because it can decode and provide insightful analysis on everything from common network traffic such as HTTP, DNS, and ARP to obscure protocols like Bluetooth Low Energy. Telluric does all this while and more while still getting out of the way by putting a touch-friendly, uncompromising packet analysis engine right at your fingertips while allowing you to write directly on your captures so you can focus on the problem at hand rather than wielding the tool itself."
