Downloads and consumer spend on the App Store and Google Play reached record levels in Q3 2017, according to a report.

App Annie claims that combined downloads reached nearly 26 billion worldwide for the period, up 8% year-over-year. This figure only accounts for new downloads rather than reinstalls or app updates.

Combined consumer spend is said that have experienced more than three times the growth rate than seen for downloads. Revenues generated was up 28% year-over-year to $17 billion.

App usage was also up, with total time spent in apps worldwide by Android users growing 40% year-over-year, clocking up 325 billion hours.

Overall Google Play had 125% more downloads that the App Store in Q3.

Emerging markets impact

India was said to be the biggest growth contributor to downloads, twice as high as they were a year prior in Q3 2016. This sharp growth coincided with the launch of Reliance Jio’s cheap 4G services in September 2016.

Other key download drivers on Google Play were countries in Southeast Asia such as Vietnam and Indonesia, which both experienced double-digit growth rates.

App Store downloads meanwhile rose 8% over Q2 2017, the highest quarter-on-quarter increase since Q1 2016. Much of this growth was powered by China, with the US and Saudi Arabia also fast-growing markets.

App Annie reported that while emerging markets drove an increase in overall downloads, it was the mature markets that spurred an increase in consumer spend.

South Korea had a strong Q3 performance in large thanks to NCSoft’s hit mobile game Lineage M, which became that highest grossing app on both iOS and Google Play.

App Annie expects much of this growth in mobile to continue and forecasts consumer spend exceeding $100 billion in 2021 on the App Store and Google Play combined.
