Vyjmenovaná slova Android software

The app is designed for mobile devices with Android operating system and allows to display a list of words listed by the selected letter.
The app is for offline use, so you don't need to be connected to the internet and still have the list of words always available.
Instructions for use:
When you open the app, select an item marked with a certain letter, for example M m and confirm the selection. The item should then expand to show a list of words listed after M. Confirming the selection again will close the item and allow you to select another item from the list.
