Pinyiner Premium

Reading Chinese is extremely important, if you live in a Chinese speaking country, plus it's the best way to learn the language. But reading raw characters has always been difficult. Pinyiner makes it easy. It breaks the characters into words, shows Pinyin above and displays the English meaning if you click on a word. Just copy&paste some text, "Share" it from another app or open a file.
Perfect for reading messages from your friends, Chinese texts on the Web and even whole books. You can also use it as a Simplified/Traditional converter.
Check out the FREE version!

Note: on Android Oreo the Clipboard monitoring might not always work because of the "Battery optimization". In this case, go to Settings -> Apps & Notifications -> Advanced-> Special app access -> Battery optimization -> Select "All apps" at the top -> find Pinyiner, click on it and select "Don't optimize" -> Done.
