Brazil, Mexico, and the United States have the most competitive app markets in the world, based on a study of nine major regions analyzed in the 2016 App Olympics report by Cheetah Ad Platform.

The Cheetah Ad Platform, owned by Cheetah Mobile, analyzed data from 52 million Android smartphone users to see how people across the globe engage with their mobile devices and apps. There are 1.8 million apps in the iOS app store and 2.3 million apps in the Google Play store. Thousands are being introduced every day.

The app scorecard is broken down by country and looks at stats such as the average app usage per user per month. It also looks at engagement, or the average number of times apps are opened per user per month. According to global results, people use an average of 27 apps and engage with an average of 39 apps per month.

Brazil, Mexico, and the U.S. have the most competitive app markets, and Brazil has the highest user engagement and app competition, Cheetah said. Brazilian consumers use an average of 29.23 apps and engage with 53.62 average apps per month.

Nine countries were monitored, each with high engagement in gaming app categories, including education, action, trivia, simulation, sports, strategy, casino, word, and lifestyle app categories, which include productivity, shopping, social, and personalization.

The study notes app categories with low competition, which represent opportunities for app developers, as well as those with high competition, showcasing which apps are in demand for these specific countries.

The study showed that communication and social apps are used three to 10 times more than other apps.

In Mexico, communications apps are used most. France has the lowest average app usage compared to other countries, at 24.56 apps per person. India has a very strong gaming category, and Canada is most active with board game apps.

The U.S. favors communication apps, with 2.52 communication apps per person. And in the United Kingdom, shopping apps are most active. Germany shows the highest competition activity in casual games compared to other apps. And Russia’s competition activity is highest in arcade and action games.
