TikTok had another massively successful month on mobile in April, a Tuesday report by leading app analytics platform Sensor Tower claims.

According to the report, users spent more than $78 million, across both iOS and Android, on TikTok last month. TikTok ranked number one on the App Store’s list of Top Grossing apps for the month, followed by YouTube, and then Tinder. This list does not include games. TikTok’s user spending is up by 10x compared to April last year.

Sensor Tower points out that the overwhelming majority of TikTok’s revenue comes from China — representing 86.6% of overall user spending. The United States comes in second place, accounting for just 8.2% of revenue. (Although when you’re dealing with $78 million in a month, 8.2% still works out at a pretty impressive $6.4 million.)

Other notable apps on the App Store top 10 included Netflix and Disney+, both of which have most likely got a nice boost from people being stuck home during the coronavirus lockdown.

Another successful month for TikTok

TikTok’s triumph in April isn’t exactly unexpected. Another recent Sensor Tower report noted that it enjoyed the best quarter of any app ever in the first three months of 2020. TikTok has reportedly been downloaded more than 2 billion times globally across both the App Store and Google Play Store. This comes just five months after it passed the 1.5 billion downloads milestone.

As many predicted, lockdown has proven to be good news for some app makers. While lots of people are struggling in various ways right now, apps have a captive audience while people are stuck home. It’s by no means a universal rule, but if you make a streaming video service, social media app, or work video conferencing app, you may be doing very well right about now.
