Focal is a pomodoro web app. I know there's a lot of productivity apps already, but I'm releasing this since I figure someone might find it useful. Focal was more of a short, 3 day project so it may be rough around the edges, but I think it does the job. In any case, Focal is open source and I would be happy to merge contributions.
Here's the github repository: https://github.com/aabiji/focal
