Instagram's Dominance Grows as New Snapchat Installs Decline Nearly 22% Year-Over-Year

Sensor Tower data shows the divide between the two social apps growing in Instagram's favor.

Snapchat vs. Instagram quarterly downloads

Worldwide new installs of Snapchat across both the App Store and Google Play have declined for the fifth consecutive quarter, new Sensor Tower Store Intelligence data shows. Year-over-year installs for Q2 2017 were down about 21.6 percent to approximately 61.2 million, compared to 78.1 million for the year-ago quarter. Quarter-over-quarter downloads declined 7 percent from approximately 65.8 million in Q1 2017.

This was the second-largest QoQ decline in worldwide new installs for the app since they peaked at approximately 78 million in Q2 2016. Q3 2016 saw a QoQ decrease in downloads of about 10.6 percent and the number of users installing the app for the first time has been declining on a quarterly basis ever since.

At the same time, rival Instagram has grown its dominance over Snap's app, posting a YoY increase in new installs last quarter of 8.3 percent compared to Q2 2016, growing from 87.3 million worldwide to approximately 94.6 million. QoQ installs of Instagram were off by about 5 percent last quarter, in line with seasonal trends for the app. All told, we estimate that Instagram was installed by approximately 33 million more App Store and Google Play users for the first time last quarter compared to Snapchat.
