I'm stagnating with my Cyrillic progress.

I have an app that's pretty cool, it's like an interactive flash card, you hear a sound then click the matching Cyrillic character. I've been using the thing religiously, but still feel very challenged by Cyrillic.

I don't feel like I'm retaining much, and the few letters I do know aren't enough to read basic words. How can I or what resources can I use to step it up a notch?
