Not good
Just a google translate of polish to english, and a very bad one at that. Some words are translated wrong, some don't translate at all and just show the polish in the english spot. I would still give two stars in that case but even worse it is not even aimed at learning. the vocab are awful choices to learn with including many words a native pole could a years without saying and numbers are all written like 234 so if you do not already know them you will never learn how the change gender and are spoken.
