Ж - Russian Declensions

I am a Russian teacher and was testing this app. Right at the beginning, I found a mistake: “свое” and “обед” doesn’t go together because of a gender agreement (in this case disagreement). “обед”=lunch is masculine, “свое” is neutral. This in unacceptable neither for advanced, nor for beginners’ levels.

This app is helpful for practice if you’re an advanced learner. I like how you can bring up the translation with the touch of a finger. I just wish you could also hear the complete sentence in Russian.
