Mediocre
The app works and translates as stated. However, the voice is too quiet to use and no one can hear it. The interface is complicated at first because its not intuitive. They have attempted to practice minimalism for a clean look but that has merely made it difficult to use. You have to press buttons to find out what they do - which is counter intuitive for UI design. So, increase the volume and clean up the UI. Also adding a repeat audio button next to each translation bubble will make it easier for the person that Im translating for to press and repeat the phrase.
