Earlier this year during its I/O conference, Google announced new tools to help users manage their screen time. Now, it's rolling out Digital Wellbeing to Google Pixel phones and Android One devices with Android 9 Pie. Digital Wellbeing gives Android users a look at how much time they've spent on apps as well as how often they've unlocked their phones and how many notifications they've received. It also offers the ability to set time limits on app usage. Additionally, with Wind Down users can limit what notifications come through during a certain time period and have the option of switching their screens to grayscale.
You can snag Digital Wellbeing 1.0 through the Play Store.
