Welcome back to This Week in Apps, the Extra Crunch series that recaps the latest OS news, the applications they support and the money that flows through it all.

The app industry saw a record 204 billion downloads and $120 billion in consumer spending in 2019, according to App Annie’s “State of Mobile” annual report. People are now spending 3 hours and 40 minutes per day using apps, rivaling TV. Apps aren’t just a way to pass idle hours — they’re a big business. In 2019, mobile-first companies had a combined $544 billion valuation, 6.5x higher than those without a mobile focus.

In this Extra Crunch series, we help you keep up with the latest news from the world of apps, delivered on a weekly basis.

This week, we’re continuing our special coverage of how the COVID-19 outbreak is impacting apps and the wider mobile app industry — or rather, the boost many apps are receiving as a result. In fact, the first quarter saw consumer spending hit record levels in Q1 as everyone was staying indoors. But as some apps shoot up the charts, scrutiny over their practices increases. This week saw No. 1 app Zoom defending itself against a host of complaints over security issues, for example, while social video app Houseparty defended itself against a possible smear campaign. There’s also a new app from the Pinterest CEO for tracking the spread of COVID-19.

Also this week: more leaks about the new version of iOS, Apple bought Dark Sky, Niantic pivoted, TikTok moved up the charts and more.
