Nice but with fatal problems

Overall a very nice app, but it has some fatal problems.

1. When the system language is set to anything other than French, "conjugaison" function does not work at all. The app always crashes when the button is tapped.
2. When the system language is not French, the explanations in the start-up screen becomes empty.
3. When the system language is not French, the buttons to switch the functions are unnecessarily translated into English. Who want them in English when this is a "Dictionnaire de français"?
4. There is no function to change the font size. Although the overall layout is beautiful and clear, the font appears too small to read longer texts.

For an app costing €5, these issues are rather embarrassing. Developers, please fix them as soon as possible.
