This is an application to training listening and writing words.
The app selects a word, pronounces it and expects you to enter it correctly.
If app don't work properly, e.g. you don't listen any sound or you see permanent "Loading..." instead "Start"-button on first screen, it's means that your browser is obsolete.
Use Chrome to avoid troubles.
Minimal supported Android version is 4.1 with Chrome 69.
