Not by itself, no. No methods can. Trully learning anything is an immersive, active, and consistent process. The app is only a scaffold, that can simulate this to some extent and only if you let it. On top of that, you have to start listening to contents in spanish. Try to repeat a few sentences that you've heard in a movie. You have to read books/articles, sometimes outloud to train the muscles involved in your mouth. Eventually, you want to graduate to having conversations. Each step challenges you and forces you to adapt. That's learning. When the app nudges you (through tips) to pronounce the words and sentences that you see, instead of (passively) just filling blank spaces, that's not meaningless. You'll get as much from it as you're willing to take.
