If you have a one-to-one district, or use Google Suite, this program is an absolute must. Hapara allows teachers to monitor, limit, and facilitate student browsing. It is a game-changer and definitely worth it!
Remind is a great way to stay in touch with parents and students, AND stay safe. Students spend more time on their phone than anywhere else, so sending them notifications (like messages, scheduled announcements, etc.) and letting them ask for help via an app/text is incredibly helpful. Don't worry: you can set office hours to stop notifications at night!
