great but it needs more
This is by far the best English->Slovak teaching app that I've found, and I've tried most of them since I'm dating a Slovak woman now. :) I just wish there were more words and phrases included. There are some common phrases/questions that aren't in there, like "how are you doing today?", "you look pretty", or "I love you". There are a bunch of dictionaries and translation apps, but I would much rather learn by using an app like this.
