The most downloaded non-game app worldwide for May 2019 was WhatsApp with more than 64.7 million installs. The full top 10 ranking of apps worldwide by downloads for May 2019 is above. App download estimates are from Sensor Tower’s Store Intelligence platform.
Messenger was the second most installed non-game app worldwide last month with more than 60.7 million downloads. Facebook, TikTok, and Snapchat made up the rest of the top five most installed non-game apps last month.
Snapchat’s dramatic ranking increase in May came as the result of a popular new gender swap filter added mid-month. The app’s first-time installs increased 2.5x month-over-month from 16.8 million in April to 41.5 million last month, bringing it into the top 10 for overall downloads at No. 5 and making it the most downloaded app on the App Store. It had ranked No. 11 overall and No. 13 on the App Store in April.
