Translation of "concavity" to Italian

I understood how it works once i opened this app. Very good. My request to you for adding the language hindi-english in download page. I AM WORKING FOR A PROJECT. THANKING YOU IN ADVANCE.

Wonderful! It is hard to believe that it so accurately captures the essence of the original. I have both the English and Russian copies of the article so I can compare the translation with the original English. It is amazingly accurate. What a difference in these free translation programs from paid ones of 10 years ago. A grateful “Thank you”.

I am learning Russian and I will recommend this app to everyone I know that is learning a language

It is the one of the best text translators can you please add in it THE UZBEK LANGUAGE THEN I'LL PUT IT 5 STARS
