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 is as hot as ever with a record 204 billion downloads in 2019 and $120 billion in consumer spending in 2019, according to App Annie's recently released "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.
