I made an implementation of Pomodoro on my website here: https://www.locserendipity.com/Pomodoro.html. I think this version works better for me than others. You write in the tasks and then mark off each 25 min chunk with a checkbox. Then, I screengrab the tab to see my productivity during the day. This aspect is missing from most other Pomodoro implementations. Also, you can right click and download the page to use offline. It will still work. Part of the problem is the actual Pomodoro method involves breaking down tasks into discrete chunks and checking off completions and most implementations ignore this crucial aspect.

I see a way to change this implementation with FlowTime where the duration of the interval is determined by how long the user spent on the give task.
