HopCount, Serious Network Diagnostics on Android

HopCount is a network diagnostic application for Android, built for engineers, systems administrators, and developers who need a usable toolkit on a phone rather than a simplified one. It covers ping, traceroute, DNS lookups, path analysis, port scanning, certificate inspection, and BGP information, with results presented the way a terminal would print them rather than reduced to a status light. Continuous monitors record results over time, diagnostic playbooks run the sequence appropriate to a common scenario, and session history is searchable so a previous run can be repeated when the question is whether something changed. There are no accounts and no analytics, and network calls go only to the targets being tested. Read more
