HopCount is a focused network diagnostic app built for engineers, sysadmins, and developers who need real answers from a phone. It brings the discipline of terminal tooling to Android, ping, traceroute, MTR, DNS, SSL inspection, BGP analysis, and port scanning, all in one place with nothing else in the way.
The interface is deliberately minimal, type a target, pick an op, and results stream in the way a terminal would print them. Beyond the basics there are continuous monitors with historical graphs, diagnostic playbooks that run the right sequence for common scenarios, subnet and VLSM calculators, and a session history you can search and re-run. Distance-aware verdicts know that a distant link should read healthy, not degraded.
Privacy is a key consideration. HopCount has no accounts, no analytics, and no tracking, network calls only go to the targets you test, and everything else stays on the device. Backups export as an AES-256 encrypted file you can restore anywhere with a password.
A serious tool for those who follow the packets, not assumptions.
