You should have told us from the start that the app isn't even in English which makes it really not for everyone. Even the video you have created is I think is in Portuguese based on what you are trying to say in the video so you aren't really talking to the general audience here. And even basing to what I watched so far in the video I really don't understand what the purpose of the app is, even the app description for it is in Portuguese. I think you should move this on the proper local board until you have made an English version of the app.
Hello, dear member, thank you for the contact, she has in English yes, even when you make the account she is in English, the video you can use the youtube caption as an option for understanding.
