Very useful, but room for improvement.
I like this app, but I would suggest the following improvements: The voice is too low. This makes it difficult to discern details of the pronunciation. Conjugations are not provided for all verbs, including some very common verbs. Conjugations and declensions accents should be show in red. This is very important! Also, ё is sometimes entered as ё and sometimes as e. All should be ё. The transitions between screens should be faster. Also, there is no explanation that I can find for the several abbreviations used in Russian. Entries concerning prefixes would be good too. Also, here is little guidance on usage. For example, if a verb requires the instrumental case this should be noted.
