We get a lot of questions about how long iPhone apps stay on the Top Charts. So we decided to dig into the data and find out if we noticed any patterns.
This post will show you what we discovered and how you can use this information to position your app in such a way that will give it the best chance of success. Some of our findings were very unexpected.
How We Calculated The Data
Before we show you the results, let’s take a quick look at how the data was calculated. We examined the apps in the top 10 and top 100 for all primary App Store categories. We didn’t examine subcategories like Newsstand > Automotive.
Next, we measured how many consecutive days each app stayed on the chart, over the last 365 days. Then we took the average consecutive days of all the apps on that chart.
For example, let’s say that an app stayed in the top 10 for a 30 day period, then it dropped out of the top 10. It then returned a few days later and stayed for 60 days.
We would add both 30 days and 60 days to the average consecutive periods calculation for apps in the top 10. If these were the only two periods that we used for a calculation, it would show as an average of 45 days, on the graph.
Using number of consecutive days gives us a much better indication of staying power. If we simply used the average total number of days on the Top Charts, an app could be on the charts every other day and have 182 total days on the Top Charts. But that wouldn’t be an accurate indication of the ability of the app to stay on the chart.
We will first give you the three biggest takeaways that we learned from these results. We will also give our reasons as to why we believe the results are the way they are. Then we will provide the graphs below in the Results section, so you can see the complete data for yourself.
