I'm looking for an app for learning German vocabulary. The app should be available for Android OS and have the following features:
- Vocabulary learning focused (not a mix of both vocabulary, grammar, etc.) or with a strong focus on vocabulary.
- Names must be presented with their article (der, die, das). This point is important, otherwise it pretty much makes little sense to learn the word in the first place.
- Plural forms of names must be displayed with each word.
- Flash card based learning systems are fine, other vocabulary learning systems are fine as well.
- Must be working offline.
- Free is a nice plus.
- Saves progress is a plus.
- Words are categorized by levels (for instance A1, A2, B1, etc.), a plus.
Please note that 2 and 3 are really important. If you are not given the gender (or the plural) of a German word, you can't really use it correctly and effectively.
