PingKit

PingKit is a set of network diagnostic tools for iPhone, iPad and Mac, built and maintained by one independent engineer.

See every device on your network, find out what is slowing your Wi-Fi down, and check whether a problem is your router, your provider or the site you are trying to reach. There are 19 tools: LAN scan, ping, traceroute, MTR, DNS and WHOIS lookups, HTTP and SSL inspection, speed test, Wake-on-LAN, a Bonjour browser, a subnet calculator, a connection monitor and more.

The PingKit Agent for Mac sits in your menu bar, keeps an eye on your network while your Mac is awake, and tells your iPhone when something changes.

Free to download. No ads, no account.
