Stopwatch timer paid? Not worth it. This is not 2008, when there were no such applications. It was all before. Now this is not working. Big competition - big companies - lots of good apps + depending on which market you are targeting. You definitely shouldn't hope for Russian especially with the paid version. Above, you have already been advised that you can start doing, I agree, I will add just what else you can put in the localized version of English in SlideMe and you can try adding AdMob.
In addition, if you did not do this, then try: analyze the competitors of your application and add something special to your app. In short, here’s what it should be about: - It should have nice graphics and UI - As few bugs as possible and especially more beautiful - Application video - Beautiful screenshots - A feature that competitors don’t have - You can create a website / blog about the application and add a link everywhere on this site
And another great advice would be the technique of the guys from 37signals (the authors of the Rework book): make an application that you yourself will use. From here there will be a lot of useful information, because you will immediately understand your audience and the possible jambs or strengths of your application.
I think now that the application is more or less popular important idea + high-quality implementation + paid promotion in the special. sites (at least in the beginning).
