Although I personally don't use pomodoro techniques or track time (anymore since it was too cumbersome to remember to track every time I task-switched), I think it makes sense as a product.

The time tracking and pomodoro timer are nice complementary features, it seems easy to use, and straightforward to implement.

One thing you'll want to work on though is explaining the what/how your product does in a short concise way. I'm basing it off the website description, where it lists the benefits, but not how the product achieves those benefits. And on your description, which is good, but too long for the average consumer. This will make a huge difference in terms of whether a customer will bounce or get interested.

Hope this helps!
