According to mobile analytics service Mobilewalla, Sunday is the best day to release a mobile app. However, they report that most developers tend to release on Wednesdays. To gather these findings, Mobilewalla studided apps released in the iTunes App Store and the Android Market over a 17 week period between May 16th and September 8th, 2011. During this timeframe, there were a total of 91,754 iOS apps released and 122,220 apps released via the Android Market.
Mobilewalla’s findings also showed a steady increase in the amount of published apps. Earlier in December the published app count rose to 987,863 across all four platforms (iOS, Android, Blackberry, Windows Phone) and is now growing at an average rate of 2,000 apps per day.
During the study, Mobilewalla sorted apps by the day of the week they were released. It should be noted, that Android developers can control the release date, while iOS app release is affected by the iTunes review cycle. Considering those factors, the report shows Sunday as the best day to launch apps on the mobile market.
“Even if Sunday was not always the developers’ chosen launch day, Mobilewalla found that apps released then statistically performed the best. That is, they made it into the list of the top 240 mobile applications. In this case, Mobilewalls is defining the “top 240″ apps as those that achieve the highest ranking in their respective stores. 42% of the iOS apps released on a Sunday made it into the top 240, while 11% of Android apps did the same.
Meanwhile, Thursdays were the worst day to release apps on Android, as only 7% of apps reached the top 240 then. On iOS, Fridays were the worst, as only 10% of apps reached the top 240.”
