Not so long ago I have registered at XDA developers forum and started to participate in some community actions like beta testing and bug reporting. Then I found another nifty Android lockscreen notifications app called Notific, which didn’t have a Russian translation. I contacted the developer, Anand Bibek, and volunteered for it. Now, after some polishing, the translation is done and included in version 2.50 of the app.
If you want to try Notific, a free version with some restrictions can be found at XDA: http://forum.xda-developers.com/android/apps-games/app-notific-lockscreen-notification-t2804624
While you can download and install the free version, I am certainly encouraging you to purchase the full version from Google Play store and support the fellow developer Anand Bibek. Cheers.
