Recording screen - best app?

Has anyone found a screen recording app that’s free, and does the job? We’ve tried several, they each have hurdles. Just wondering if anyone has a favorite. Thanks, jr

I use Microsoft PowerPoint to do screen recordings.

After you record, then right click on the video in PowerPoint and his “Save Media As”. I have found this to be a reasonable file size and allows for students to only record a portion of their screen, and not the whole thing. Makes it easier to not have personally identifying information.
