It’s no secret that most App Store sales success is reflected by consistent placing atop Apple’s top charts. To that end, analytics agency Distimo put together this little piece on how many downloads it actually takes to rise up the ranks. Unsurprisingly, the necessary numbers are pretty high. A little surprisingly, those same numbers aren’t constant country to country. Check out the stats (via Inside Mobile Apps):

United States – Top 10: 80,000; Top 25: 45,000; Top 50: 25,000
China — Top 10: 30,000; Top 25: 15,000; Top 50: 10,000
Canada – Top 10: 9,000; Top 25: 4,000; Top 50: 2,000
Japan – Top 10: 20,000; Top 25: 9,000; Top 50: 6,000
South Korea – Top 10: 20,000; Top 25: 9,000; Top 50: 5,000
United Kingdom – Top 10: 18,000; Top 25: 8,000; Top 50: 5,000
Germany – Top 10: 12,000; Top 25: 5,000; Top 50: 3,000
France – Top 10: 10,000; Top 25: 5,000; Top 50: 3,000
Italy – Top 10: 8,000; Top 25: 4,000; Top 50: 2,000
Australia – Top 10: 8,000; Top 25: 4,000; Top 50: 2,000

As you can see, it takes 25,000 downloads per day for an app in the US App Store to break into the top 50. To hit the top 10, it takes a staggering 80,000. That’s 2.4 million downloads a month, or almost 29 million downloads each year. Taking it to the opposite extreme, such bestsellers move almost one app every second of every minute of every hour of every day. That’s kind of nuts.

But there’s more.

Just as the figures differ across the globe, days of the week seem to matter, too. While each weekday accounts for 13-14 percent of an app’s weekly total, weekends matter even more. Big-time apps move 16 percent of their seven-day volume on Saturday, and that jumps to 17 percent on Sunday.

With all the casual titles out there, and iOS’ innate mobility making everything easier, it’s only natural that the day of rest would become the day of apps.
