NTP Inspector is an application that allows you to check servers running the NTP protocol over the Internet and report some basic information. It sends an NTP packet from your device to the server and reports backs almost everything included in the response, like the protocol version, mode, the server Stratum, its precision, reference time, as well as whether there is a leap second today or not. With this app you can troubleshoot NTP servers from anywhere, as seen from your device, and not a remote server, with complete privacy. The app was created when I received an alert for one of my NTP pool servers while outside and without laptop access, with no other option to query it to see what's wrong.
