Pacifica tries to determine the right language for each user based on the settings on your phone. If we end up getting that wrong, or if you'd like to change it, you can do so easily.
Tap on the cog in the upper-right corner of the home screen. Then tap on the row for "Languages" and select which language you would like. This setting is sticky so we won't change back to the original language for you, you'll have to repeat this process to change it back.
