Hi there,
I started learning German around 3 years ago. I'm also a busy student, so often found myself not having any time to expose myself to German most days. So I had an idea for an app that constantly shows you new words using your wallpaper. So every time you unlock your phone, you learn a new word, with the translation, plus an example on how to use it in a sentence.
I've been working on it for around a year now, and it's gotten fairly good at this point. It has 10 languages including German (most of the European languages are there, French, Italian and so on). I will be adding more features soon.
Let me know what you think:
