There are some apps that are giant, ugly processor hogs. They take up huge amounts of disc space, and are all around pains to use. PicoTimer is… different. It’s 132KB, and takes up less than 1500 square pixels. It can time things in hours, minutes, and seconds, and is overall extremely simple.
PicoTimer is entirely portable. It’s a single EXE (though preferences are saved in a separate INI file), and when you open it, you’re presented with the tiny black window shown above. Just click on it and type in a time to get going. It supports inputs in words (1 hour), abbreviations (1h 30m), and various forms of spacing (1 30 20, 1:30,20, etc). It does not support, however, using numbers as words (one hour, thirteen seconds), and when using words, it is a little prone to mess up (1 second gave me 1 minute). After the timer, it’ll play a beeping sound.
Even with the slight word input issues, PicoTimer is still great. It supports enough other types of input that you’ll probably never even notice that issue. It’s a great program for anyone who wants to have a tiny, simple timer available at a moment’s notice, and is entirely, 100% free.
