Compare BCrypt hash to Bcrypt hash PHP

Compare BCrypt hash to Bcrypt hash PHP

here's what I'm up against.
I have an app for iPhone that I am building that communicates with
password protected pages on my site. The app can get through the password
protection fine and can get the response from the page just fine. The
problem is that when I try to login to the site from my app it gets
rejected. I believe this is because I am hashing the password with Bcrypt
in the app before sending it to the site and then checking it with
password_verify(), which of course takes the plain text of the password
and then the hashed version, but I am giving it two hashed versions of the
same thing which it is not accepting.
My question is this: is it possible to compare the two encrypted passwords
using password_verify or some other function, or not? And if not, is it
secure enough to (dare I say it) send the password in plain text from the
app?
Thanks to everyone in advance!
