Okay but has some issues.

So, this app has probably the best dictionary for Russian in the store, but the app itself needs some work. The advanced search features dont work (for example, Id like to be able to search for words containing roots, which is handy because Russian has lots of prefixes). And Id really appreciate flashcards (the old Oxford app had them before this developer took over.) Not bad overall but could use more to make it worth $20.
