Its not easy to be part of the top 10 apps in the App Store. You'll need at least 30,000 downloads a day! Research firm Distimo says they found that more people download apps on the weekend, and it takes considerably less apps to crack the top list in other countries.

Some developers on Quora say that depending on the day, those apps are doing 200,000-300,000 downloads. That's how they get to the top 10. But 30,000 alone won't cut it then!
