Voice Search Not Working
The voice search feature stopped working one day and I had to delete the app and re-download.
Other than that, I use this as a primary dictionary. Sometimes, it fails to explain the subtlety a word conveys but overall, its a good reference for non native speakers with a decent price. I wish they expand the vocabulary list and utilize the smart phone more. For instance, they can include sounds or even videos.
