Good and improvement
This is a good dictionary app to me. Ui is clear. Explanation is easy to understand. Words can be saved for future revisiting, which is very useful for me as a learner.
The improvement would be to synch up the saved with the web site. I still spend more time on a pc and a real browser than a phone. So it would be good to get a copy of the saved words on both places. I think people call this "cloud" these days.
