Calm Pomodoro

One of my design principles is that:

The product should adapt to you, not vice versa.

While writing my PhD thesis I found that all Pomodoro timers (Wikipedia) out there let you decide the rules but then held you to them strictly. I on the other hand wanted a tracker more than a timer, gently alerting you about the flow of time but not shouting at you to take a break if you were in a flow. The result was this app.
