Hello,
I am a Czech translator with a degree directly in Translation Studies and Czech Language and Literature. That means that I have perfect knowledge of Czech and English and can create a translation that will be completely user-friendly, which is very important for your app.
Your file looks like auto-translated, but don't worry. I'll correct the funny translations of countries meaning in Czech "I have heard and McDonald he is" (col. DH) or "to go" instead of "Togo".
The job should take no more than an hour and a half. In case you need it quickly, I can work on your file right now or Wednesday morning.
Feel free to contact me in case you have any questions.
Have a nice day,
Veronika Friedrichová
