This app has been developed as part of a student dissertation. It is being put in the Play store so other people can have a chance to use it. It is anticipated that the app will generate some useful feedback, which can be used to help improve its functionality.
The app is essentially a tool to help people learn how to pronounce Chinese numbers between 0 and 1 quadrillion. Please download it and give it a try, it is free. I hope you enjoy using it.
Version 1.2 has implemented a subtle extra feature when the sound is being played in the number converter section of the app. Now, if you type in a number and press the listen button, you can then tap on the pin yin or Chinese characters that are on screen, to get a zoomed in view, whilst the number is being read out.
