The best thing about this application is that it helps me to find out how popular my applications are among different countries with respect to their language preference. I can compare which one has more downloads than others. It is really helpful for getting the insights of what people like and dislike most within an application category. I have not come across any drawbacks so far regarding its use. We've just started using it recently but there's nothing much we would say as such. It does exactly what it says! There's no other better solution available in the market right now. A free analytics tool for Android apps. You can see where you're going wrong and make changes accordingly.
