I'd have to think about the pomodoro thing. Maybe, but I developed an almost unconscious reflex to hit the 'ok' button on the timer to make it go away. I would try very hard to not have it make me think about anything, just confirm which task I was in the middle of. The main thing it caught was when I hadn't re-started a timer after finishing something and stopping it, and when I switched tasks without telling the timer. I'd take a second to fix it, but not stop to reflect, nor break down my tasks. After the first reminder, I'd try to ignore them again.
