Once upon a time, a guy used random pomodoro timers he found on the internet.
Every day, he would run slightly over one of the time segments, want to check how long he went over, and then be annoyed when the random timers provided no means to do so. Also they loaded slow and had too many buttons.
Until one day, he realized "wait, instead of complaining, I could just solve my own problem".
So he solved it. Usable @ http://riwsky.github.io/mo-pomo/
