The company's App Store index measures the average aggregate daily download volume of the top 200 free iPhone apps in the US.
For the month of April It shows app downloads continuing to fall to a daily average of 4.23 million after a considerable January boom and then a sharp drop last month following Apple banning bot farms.
Meanwhile, Fiksu posits that increased competition in the social networking and gaming categories caused mobile marketing costs to slightly increase in April, leading to a rise in the cost per loyal user rate to $1.46.
Downward trajectory
"April's continued downward trajectory of app downloads was expected, as no major events sparked discovery during the month," explained Fiksu CEO Micah Adler.
"Additionally, app marketers continued to scale back their use of robotic install tactics in response to Apple's policy on third-party marketing services," Adler continued, referring to Apple's crackdown on the use of bot farms to increase an app's standing in App Store rankings.
"However, we observed more aggressive advertising spending as marketers moved out of the first quarter lull and began to seek new opportunities to compete for rank especially in the dynamic social networking and games categories, which experienced volatility during the month."
