Gallifreyan Translator is a free Android app developed by Travis Redpath. It is a lifestyle app that translates English input to Circular Gallifreyan, a fictional language from the popular TV series Doctor Who. The translated text can be shared with others and exported as a generic image file.

Circular Gallifreyan is a unique language that contains some letters with lines extending from them. The app ensures that the number of lines remains the same, but they point in semi-random directions. Therefore, the same text can appear slightly different in different translations, but both are always correct. The app is easy to use and a must-have for all Doctor Who fans.
