Presents two prompts for you to split a duration into minutes and seconds, then calculates it all as total seconds – copies the number to your clipboard, then provides the original duration and total seconds so you can compare.
I built this to quickly convert a timestamp on a YouTube video into seconds so that I can append that information to a YouTube link, which requires total seconds to jump to a specific moment.
Siri may not properly speak back the unformatted duration you type in, but should pronounce “sec” as “seconds” as iOS can recognize the units of measurements.
