Hi Dmemme,
Do try out our application. We designed it for students who are serious about learning Russian. We do include translations, but that's really a bonus feature. The primary focus of our application is on displaying grammatical information and stress marks.
Hi Hana,
The full version of our application costs $69. You can get it here: Grammatica. You can try it out for free for a period of 20 days. If it suits your needs, you can purchase the full version.
We are planning to release a large update to our application in the next few weeks. It will make the application run quicker, be more stable and it will feature an updated database of Russian words.
I would recommend that you sign up to our facebook group if you're interested in our application:

Best regards,
