1st Generation. Allows you to control the amount of Internet time each day, the amount of time on specific apps (like social media) and set bedtimes. Also allows you to reward the kids with extra time if you want. https://support.meetcircle.com/hc/en-us/articles/115001380592-Setting-Up-Circle-1st-generation-and-Circle-Home Works great.
