App intelligence firm Sensor Tower projects that Apple’s App Store will reach 5.06 million apps by 2020, making its catalog 73 percent larger than figures expected this year. The App Store debuted in 2008, reached 5,000 apps by the end of the year, and totaled 1.75 million apps by 2015. “New games fuel the App Store’s growth, because of both their popularity and because game makers have to release new titles often to keep users engaged,” reports TechCrunch. “48,231 new apps were released this May, with 43 percent of those being games.” Those were followed by apps for Education, Entertainment, Business and Lifestyle. Interface upgrades and search ads are expected to help with app discovery moving forward.
