The Translate App launched in January 2010. In included basic functionality that mirrored the website. I was brought on soon afterwards to do a usability cleanup and to make sure the app matched the Android.
I redesigned the home screen to simplify the options. Most users were simply using the App to translate quick words on the go. I also changed the order of the page to reflect the natural hierarchy; users rarely changed the input/output languages, but would often run several queries in a session.
The translation process in the old App had a button to display what languages the user had set. Pressing button created a dialog box with two language dropdowns. Those dropdowns brought the user to another page where they could select a language.
My redesign put these dropdowns on the homepage to serve as the display and enable the user to change their selections up front.
This was just a basic style and hierarchy cleanup. However, this afforded us an opportunity to message the user about our new ‘Conversation Mode’ feature.
