Pinyin on your screen, in any app

Tap the accessibility button, and Rubify writes the pinyin above the Chinese characters you are reading: in your browser, chats, PDFs or textbook pages.

你nǐ会huì读dú这zhè个ge字zì吗ma？

Tone marks, word-aware. Characters with several readings get the one their word needs: 银行 yín háng, 行人 xíng rén.
Stays out of the way. Your touches reach the app underneath; a small bubble refreshes the pinyin after you scroll, hides it or closes it.
Private. Everything happens on your device. Rubify has no internet access and collects nothing.
