ClassroomScreen.com

One of the cool tools (according to my in person students) has been ClassroomScreen.com. You open the site and display the screen on your full classroom screen. You can then drag in tools and widgets that work for your classroom.

Below I am including a timer, a stoplight (to help students know how much time they have left for group work), a poll, and other tools. You can manipulate the background image to any image you wish.

Two favorites were the QR code generator and the noise-level indicator in which an alarm goes off if the class volume gets too loud.
