Alongside the physical health concerns during COVID-19, there’s been a massive uptick in mental health issues like anxiety. Those worries are highlighted by a big surge in mental wellness mobile app downloads, as noted in a new report from app analytics firm Sensor Tower.

The firm notes that the top 10 mental wellness apps experienced a big increase in downloads in April from the pre-lockdown January 2020. In all, apps like Calm, Headspace and Meditopia racked up a total of 10 million downloads last month.
