The interface is beautiful and easy to use. It has a feature to add images and voiceover. I like this because it can be used for multiple languages. The only thing I don't like about the app is that it's not very good at keeping track of my progress. Sometimes it will say something like "you haven't done anything yet" when it clearly knows I completed everything. However, other times it will tell me I've completed something when I haven't. I have no idea why this happens sometimes but I just have to keep trying until I get what I want. This is great if you are looking for an app to help learn multiple languages. You can create lessons with different types of exercises, such as reading or writing.
