Hello Andrey,
Translation into spanish is for me not very good. If i can help, please feel free to send me the list of words or senteces, and I will give my opinion on how to best fit an spanish translation.
For exampla, there is a button stating “Hacer” which means DO, but should state “hecho” or “listo” to mean “Done”.
Good job with the application, I’m new, but enjoying very much its face recognition.
