Network Diagnotor: Speed Test

Network toolkit for engineers — Ping, Traceroute, MTR, DNS, port scan, Whois, and Speed Test in one app. Find where it slows down in 60 seconds. No sign-up.

Network Diagnotor is the on-the-go network Swiss army knife for engineers, ops, and developers — Ping, Traceroute, MTR, DNS, TCP port scan, Whois, and Speed Test in a single app. When something feels slow, choppy, or just plain broken, you can pinpoint whether it's Wi-Fi, the ISP, the target host, or your own app in 60 seconds.

No sign-up. No account. The diagnostics that matter run on-device.
